Gentlemen :

I hate winter and all that comes with it . Winter makes for lousy conditions for flying except for multi rotors most times . Winter does afford more opportunities for building and researching new projects and ideas though .

Back in the 70s when my mate Franky and I were teen agers , Frank had this crazy idea to build up a snow sled based upon curved cutain rods with a COX TD049 as power . A non-RC rig for large fields operations , I guess . The succesful version that he built did , in fact work . Too well as it was never to be found again as it skated towards the center of town . So when I ran into a 3D print of a snow sled on Thingiverse.com , I had to check it out . The version I downloaded for its STL files was of a slick looking DF one . A great candidate for a simple 2 channel RC rig . I printed the first one of these for Frank .

I ended up making a few mods for the Thingiverse model that are included here . Copyright and proper crediting would not ethically allow me to repost the original model files , BUT I have included the screenshot for those for one to download for himself . My mods are for a motor mount with vertical extensions to mount an 1806 motor and 5 inch prop . Other mods are for a frontal LED lighting bracket and an antenna mast for the radio RX .

Since a recent heatwave has melted a lot of the snow around the shop , I resorted to testing this sled in the workshop . And 'Boy Howdy' , does it ever scoot along the shop floor ! The...Continue Reading

Gentlemen :

The Armadillo quadcopter I recently posted was sent to my mate Dennis (cynr100) in Cairns before I had the chance to fly it . Dennis has posted 3 videos of it in action since he completed the RC gear installations and performed a basic setup . He seems to like the way that this one flies and remarked that it was quite responsive although under powered with the DF units I sent with it . I believe that these fan units will be soon replaced with brushless motors instead . Very much looking forward to seeing the pix of that mod . Those would definitely give the Armadillo a boost in forward flight .

Seeing the video clips of this posted on Dennis' YouTube channel , I have decided to print off the Rotorbits compatible parts for one of my own . My quad will be using a newly purchased pair of AEO 50mm DF units which have 5700KV motors already installed . The specs boast a moderate 385 grams of thrust each on 12.3 volt power . Since the Armadillo's weight came in at around 670 grams , those DFs ought to make her skate !

The linx for Dennis' video clips posted on YouTube are :

Gentlemen :

A recent posting on Myminifactory.com by a fellow named Reg Taylor is of a 3D printed model of the Bubbleship in the movie Oblivion starring Tom Cruise . A Russian fellow by the name of Native18 posted a video of his Bubbleship on YT a couple of years ago .

Having seen that video prompted me to download the files for this model and begin its 100+ hours of printing . Note that the printing and finishing of the model itself is the EASY part of this project . Making space for the required RC gear IS the main challenge of this project .

With only the trim left to print off , I have accumulated just over 100 hours with the 3D printer . Countless other hours will be required to properly finish sand the parts for assembly as well as their modifications to be able to install the RC gear within . The drill press in the shop is being used extensively using hole saws and milling cutters to further hollow out the thick / heavy parts of this model . Without any modifications of the parts at all , the weight of them totalled 800 grams ! An extensive lightening is being employed during the mods .

The main body design of this model is very small in comparison to the canopy section . Fitting in a battery within these constructs is proving to be a major concern . If the canopy were to be enclosed with a translucent tinted color shere , placing the RC gear inside of the canopy would be no problem as its diameter is just under 5 1/2 inches . BUT , I want to do things a...Continue Reading

Gentlemen :

Finally completed the power mains wiring of the Armadillo quadcopter this morning . Ready to ship to my mate cynr100 in Australia a he spoke for this one quite early in its construction . Can't wait to see the videos when he completes this frame with the motors / ESCs installation .

As mensioned in the first construction blog , this project was based upon the Rotorbits construction system using parts that I designed in OpenScad and printed on the 3D printer in the shop . As the model sits in the pix , its weight is a shade over 570 grams . If it performs as well as the other variants of the V3 quadcopter , it will show 'punch outs' which will be ballistic in nature . This one should be a good performer as the other variants are .

So the Armadillo is on a long range flight at the moment . An endurance one to Australia ! Lots of batteries for this flight . LOL Dennis will be completing this one soon and possibly renaming her . The videos ought to be good ones to see . Best of luck with this prototype Denny ! Seeing how well this project turned out , I will have to print one off for myself methinks .

Check out the pix and post any comments or suggestions as you wish . Regards to my mates , readers and everyone who tends to push the construction envelope . RickC_RCAV8R

Gentlemen :

Too hot to be working on the shop expansion this afternoon so I spent a couple of hours working on a design variant of the V3 quadcopter frame which I have been flying . The V3 frame has proven to be very agile due to its ample power combination and light weight . Although I have not flown it in the ACRO flight mode yet , I am sure that it will have the power as standard 'punch outs' are insane . Ballistic !

The 3D printer has been going full bore making parts for this frame design . I am becoming more proficient with OpenSCAD as the part designs are coming to fruition is short order .

The Armadillo (tentative name) is a variant of the V3 frame with the added twist of a pair of 50mm ducted fan units . The strut mount shown in the pictures was the first attempt at this vital part and is now modified with longer length struts . The question of using this part in the design has to do with its configuration . Up or down . The lower configurated fans would present a look like the standard 'Century Series' fighter jets while the upper configuration presents an A10 Warthog look . If I use the lower configuration , a mounting slot in the DF units could be used as forward LG mounts and greatly simplify the design and overall weight by a considerable amount . I see no airflow problems with the 4 quadcopter motors in either configuration as the DF units are centrally placed .

The 4S battery clamps are fully adjustable for correct CG placement . Having these mounted opposing the DF unit mounts makes the CG offset by these parts negligable . Also , the clamps can adjust for a wide range of battery capacity sizes .

The early construction pix shown of the Armadillo show the early , first attempt , shorter DF struts . Any suggestions for this design would be appreciated as it is easy to modify and reprint parts should they be required .

As usual , regards to my mates and readers . Special regard to those who love to push the theory envelope on occasion . Cheers RickC_RCAV8R

Gentlemen :

Last weekend saw a day trip with my mate Frank (Mountainrider) to a local hydro transmission corridor east of Castlegar . I hadn't visited this area in quite a few years and was anxious to go . This trip , I decided to take along the Chaotic quadcopter which I had rigged with a DVR camcorder .

Most of the morning was spent looking for an old trail I hadn't travelled since 1974 when I was in high school . Although , we did find some segments of this original trail , Frank's idea of visiting an alpine lake appealed more . The trip into the mountain side to get to this lake only saw one minor obstacle of a fallen tree which we had to winch ourselves over . The Polaris RAZOR has ample power for performing these types of operations , blazing new trails or going thru mud bogs which we found later on .

The alpine lake has very impressive scenery in my opinion . After a quick lunch at this small camp spot , I grabbed the Chaotic and stuffed in a fresh battery . I noted that I had a chipped prop from the trip but decided to fly anyway , IF I would take it easy using the throttle . It was a nice uneventful flight over the lake . My thoughts were to weigh the risks of flying over this frigid water temp glacial lake without any floatation installed on the quad and any possibility of having to go swimming for any wreckage .

Frank shot these pix shown here . The flight video did not turn out at all as the memory card in the DVR was toast ! A major...Continue Reading

Gentlemen :

I found some time to spend with OpenSCAD in the past few days to work on the previous 3D print of a Rotorbits Vtail adapter . The files presented here are all printable .STL files . All of the examples here are still under improvement but may work as testing parts . Included with the Vtail adapter construct that fits the standard 10mm square CF tubing , is an ESC mounting plate .

Files included are for : 10mm square tubing main spar connection to the 10mm square Vtail construct ,
12mm OD round tubing main spar connection to the 10mm square Vtail construct , and
14mm OD round tubing main spar connection to the 10mm square Vtail construct .

Comments and suggestions for these types of parts would be greatly appreciated . Current idea for printing include a 50mm DF fan unit mount to fit the 10mm Rotorbits square tubing , LED lighting fittings , control surface mounting tabs , etc.

Please feel free to let me know how these printed parts worked for you . Any pix of their application would help my future motivations for these sorts of parts . Thanx for your interest in them .

Gentlemen :

As there are not any level areas around my work shop where I tend to do most of my multi-rotor flying , I gradually became distressed with that fact . Looking in the scrap pile of freezer panel cutoffs from the shop expansion project , I spied a panel that could be used as the basis for an RC Helipad .

This simple project only took about an hour to complete and consists mostly of the 2 X 6 inch spruce frame and 2 X 4 inch tapered legs . Having these stake like legs aids in the levelling of the platform over nearly any ground . I drove the legs into the turf with a sledge hammer and scrap block (as to not damage the finish) until the platform was totally level .

With this helipad installed , I will no longer have to endure the previously unlevelled calibrations which led to tilted hovering in flight and subsequent drift . Another benefit of having this stable and level pad to land on is that it aids my concentration while trying to negotiate a 4 foot square pad .

Gentlemen :

Since I have the 3D printer upgraded with printed parts and tweaked out , it was time to try my hand at OpenScad for designing my own parts . This Work In Progress is my first attempt at this exercise and will have to be improved upon . A basic Rotorbits Vtail connector is shown here .

The specs decided upon for this part was to include it as a 'parametric' module so that any parameter of its size may be altered . Having this capabilty allows for the anhedral sweep angle , tubing sizes , fitting allowances , arm lengths and mounting screw holes to be changed at will . As of this printing , I have to figure out the Hull and Polyhedron commands to be able to fill in the vacant spaces between the 3 arms . I believe that the hull commend will be the key to solving this infill problem . As this part sits now , it uses about 16M of PLA filament and weighs about 48 grams . With its 5mm wall thicknesses , it proved to be very strong when tested with a pair of pliers . Only some minor sanding with 220 grit sandpaper and some inside filing of the square tubes was all that was necessary to make this part fit the Rotorbits 10mm tubing . I set the fitting allowance to be .3mm (point 3mm) in both directions . It worx well .

If there is sufficient interest in this sort of thing of 3D printing of Rotorbits parts , I will post further as I go . In the mean-time , I have included the current early version of the printable STL file .

Gentlemen :

Some of my readers and friends have wondered why I have been silent in the last couple of months . Well , it is quite simple really ; the shop expansion project .

This expansion project uses a lot of salvaged materials like the beer cooler / freezer I salvaged along with my mate Frank (Mountainrider) when a local business went south . The original cooler was some 30 feet by 16 feet in size with a large freezer type door and a pair of triple glazed reach-in door sets . Other goodies with this unit was the heavier grade of electrical wiring , boxes and vapor proof fittings . Special product display wiring for lighting is also a part of the display door frames . The plan for this expansion is to provide storage for the tools and motorcycle restorations of my old shop that has to be torn down , and a proper greenhouse in the front , south facing side of the building . Construction of this building is pretty straight forward with its 'beam on post' type / 'post on peir' techniques . An above ground deck , for lack of better terminology . My part of the cooler will make a building which is 20 feet by 16 feet in size . Frank's hunting game storage building will be much smaller .

To date , the materials to construct the deck itself has totalled just under $1000 . Not bad for the size of it really . The main central post and beam structure is nearly complete to accept the roof panel mounting by gravity . I included a number of earthquake type strapping on each...Continue Reading

Gentlemen :

A whole new world opened for me in the RC hobby . This recent purchase is by far the most prolific one that I have made in RC modelling in 45 years . An Anet A8 3D Printer . I found this Prusa i3 knock off on a flash sale by Gearbest.com for $161 US . With the exchange and shipping by DHL , the final price landed at my door worked out to be just over $250 CDN . The A8 , in this form of a KIT , enables the lower price . This very quiet desktop printer is capable of printing the most common PLA and ABS plastic filaments with ease .

The kit required nearly 2 days of work to assemble properly and to set up for printing . Building a piece of equipment in this manner enables the user to have the necessary knowledge of dis-assembly and modifications of the printer , its proper setup and any troubleshooting to come . While the printer was in transit , I availed myself to extensive Inet research on the 3D printing subject . I downloaded several tutorial , tech tip , modification and general knowledge videos ; enough to fill some 4 DVDs for the shop reference library . I also downloaded some extra free software like OpenScad , Meshlab and CURA to have the necessary ones to perform complete designs to the printing stages . Popular 3D search engine websites like Thingiverse.com and Yeggi.com provide hundreds of thousands of FREE print files for nearly anything that can be imagined . Simply searching for subjects like Walkera or DJI yields a plethora of printable...Continue Reading

Gentlemen :

Since the original V3 Vtail tricopter is such a blast to fly , I decided to use up some of the ROTORBITS parts in my inventory to build up a second frame . This frame is yet un-named and I invite suggestions .

My love of the science fiction TV series prompted me to build this frame with a 'spacey' type of body over a simple CF frame . Extensive use of red and black colored PolyEthylene 1.5mm sheeting was used . An 18 inch sheet metal bar folder helped in bending some of the form pieces seen in the pictures was instrumental . I feel that I achieved a simply formed frame of these laminated sheets to form an acceptable body design . Note that these armor plate styled parts are bolted in place at strategic locations with the Rotorbits 2mm bolts and NYLOCK nuts . The addition of the latest installed plastix are glued in place and sealed with clear silicone .

The latest addition to this frame is with regard to the motor nacelle cutouts . When carefully cut out , they simply slip over the Rotorbits motor mounts as a friction fit and work well . A dummy motor helps with the design and installation of these nacelles .

The frame is completed as far as I can go at this point as I await the RacerStar BR2205 motors and 30 Amp ESCs in the mailbox . It will be an anxious 3 week wait to finish this one off . Including the installed KK mini FC , a 6 channel Walkera RX , Gen Ace 3S @ 2200mA battery and the power supply wiring bus , this frame's AUW at this point is...Continue Reading

Gentlemen :

It is with great pleasure that I can finally offer a video of the Yoni tricopter that was constructed last year . As I was finally able to scrounge up the remaining parts from a crash victim , this 'leftover' was realized . My rcgroups mates Sam (CO2X) , and Dennis (cynr100) were instrumental in their encouragement and advice with this project . Thanx mates ! Without their help . I doubt that this would have ever left the work bench .

YONI Tricopter Mar 2017 (2nd ever flight of my 1st tricopter) (4 min 32 sec)

As noted in an earlier blog posting of this model , its main frame construction is of Lite Ply , StyroFoam and some salvaged aluminum square tubing from an old handrail . The features of the Yoni include a KK2.1.5 flight controller running RC911 firmware , generic 30 Amp ESCs on Gen Ace 3S @ 2200mA power , Emax CF2822 motors twisting Gemfan 10 X 4.5s and my usual wiring hardware trix . This AUW of 950 grams in this configuration yields flight times of approximately 5 1/2 minutes on factory default settings .

The video included is of the Yoni's 2nd ever flight and is the raw footage of that . It is dedicated to my mates Dennis and Sam , of course as it would have never been possible without their input . The stock / default settings of the firmware yielded a flight that displayed exceptional yaw rates and decent lateral and fwd / back transitions . The 'punch outs' are a little weak but may be possibly solved with a different motor /...Continue Reading

Gentlemen :

A quick salvage project of a crash victim in this ZMR450 . I had a lot of fun with this one over the past couple of years but the 'battle damage' was becoming apparent . A quick , single afternoon salvage and clean up of the frame was involved here . I made a decision to upgrade the motors on this one to 3236s which are now ordered and to complete the wiring cleanup before rehanging it on the shop wall in wait . Besides , the wood stove is lit , the coffee is percolating and there is a snow flurry storm happening right now . Too windy to fly !

One of the features I like to include with most of my models is the installation of a 'buck / boost' power supply module for LED lighting . This type of PSU is capable of providing a 'set point' adjusted voltage that is derived from a wide voltage range input battery source . It is possible to wire in LED / lighting arrays to operate at a different voltage than the battery input quite easily . A highly recommended addition to ANY model .

Other features of this MR is the KK Mini flight controller which will be running RC911 firmware . Also note the use of printed circuit type terminal blocks for the motor connections on each of the arms . These allow for a very quick change of polarity and motor replacement without having to unsolder anything .

Gentlemen :

I haven't posted in quite some time and appologize to my readers and mates globally . This winter has been harsh at times and I have been keeping up with the necessary chores . BUT , I do spend a fair amount of time in the worshop in front of the wood stove and a pot of coffee . Progress on the current VTOL / Quadcopter projects are going well and are nearing the point of being successful test platforms for the ongoing altimeter monitoring project .

A recent trip to my mate Frank's (Mountainrider) place saw him clearing out a storage area of a few RC models he was not flying . I intercepted them from the scrap bin in favor of salvaging something useful ; and I did with this EPO park flier B2 toy model .

A quick stripping of the small DF fan units and other RC gear from the EPO fuse saw that the initial construction for a viable 'Eflite Convergence' type model would be a matter of recutting the flying wing . As I cannot afford a real Convergence at this time , this model will be an attempt at something similar . The plan for the flight controlling firmware is the VTOL package found elsewhere on this website . This firmware takes care of the motor tilting and all of the motor / function mixes between the hover and full forward flight modes . (Happy Sundays found in VTOL section) This model will be based on a tricopter based framework with custom throttle mixes for the rear motor , front motors for YAW and the motor tilting itself . Elevons will be the...Continue Reading

Gentlemen :

My mate cynr100 sent along an older NAZA-M flight controller for one of my camera platform projects . Thanx Dennis ! His suggestion of using this flight controller along with a Quanum Venture quadcopter as a stable camera platform turns out to be an optimum choice of equipment . I am finding that the stability of the NAZA-M is far superior to others I have used to date . A marriage made in Heaven !

As I have been bashing around the Venture for over a year now , I have made some obvious mods which are worth noting . The LG of the original model was quickly skimmed off in a mildly violent sideways landing whilst correcting for a crosswind . I elected to build up a bit heavier aluminum skid type for the frame as seen in the pictures . This tubular aluminum skid is basically bullet-proof .

A commonly available 555 timer IC served as the basis of a typical flasher circuit fo the clear high intensity 5mm LEDs used on the Venture . The flash rate and duty cycle for the flashing is adjustable via a pair of 10K ohm pots . This circuit along with a Red and Green LED general lighting arrangement is distributed on 4 custom built circuit boards . The plan for these LEDs are for the upcoming altimeter monitoring project which is in the works now . I wish to turn on the Green LEDs for any climb rate greater than 1 meter / second , Red LEDs for dives greater than 1 meter / second and to FLASH ALL Leds when the model is over the legal height limit . Having these multi...Continue Reading

Gentlemen :

2017 has been very busy with the snow in my area , some quad flying in the snowbanks and my annual concentration on electronic projects . A recently completed project of an FPV and weather station has already proven to be a valuable addition to the work shop . Having an instrument grade wind direction indicator together with the current time , barometric pressure and ambient temperature married with FPV capabilities of viewing the video image on my computer screen is what I was aiming for in this project . And , its positive results made this worth while .

The weather station is based upon an Arduino 2560 Mega micro controller and runs the firmware needed for all of the instrument sampling and sensed quantities converted . A real time sensing of temperature and barometric pressure is done with a commonly available Bosch BMP180 sensor . This and an instrument grade weather direction vane provide the climate information viewed on a 16 X 2 character LCD display . FPV vide RX wiring and the physical RX mount are up on the mast attached to the work shop and are routed thru a video capture dongle straight into the shop computer . As I can't seem to get used to viewing video with goggles , having a 19 inch monitor suits me just fine .

All parts for this project totalled under $50 US and were mounted within some salvaged electrical enclosure boxes . So if you are looking for a simple addition to your shop such as this , this project sure fits the bill . I will be available for consultation and providing any advice and code should anyone care to try this project for himself .

Gentlemen :

This week saw the extensive body modifications of the RAD robot for the various equipment to be installed . The time consuming process of cleaning up the wiring harnesses had to be done before any of the mods could be started .

Arduino modules build over last winter were taken out from storage and re-tested for proper operation . These include the text-to-speech voice synthesizer and FPV camera / VTX systems . Other equipment such as LED lighting for general purposes had to be modified with cabling to be able to connect to the robot's system .

The construction of the current assemblies will be concentrated upon over the next week or so as I await electronic parts and proto circuit boards in the mail . This time could well be used to begin the rewriting and addition of custom coding to existing 'open source' Arduino program sketches for each particular module . These program modules require individual testing to verify the proper operation of each module before they can be assembled in the master 'main' robot operating program . It is a good thing that C++ allows for this while keeping the code easy to read .

Today's construction saw the installation of a pair of 1mWatt red LASER modules as the main eyes of the robot . These are set to provide a visible navigation aid and can be switched ON and OFF from the radio TX to protect my kitty's eyes from damage .

Since this robot must be assembled from the head down and the modifications have to be...Continue Reading

Gentlemen :

Season's Beatings ! It's Black Friday .

Rather than setting out for the local mall and having to fight the Zombies over saving $40 on a new TV , I decided to stay up in the shop and work on my main winter project of the RAD robot . This robot was a viable product in the mid 90s . I inherited this unit from a mate of mine who got it at a yard sale for a couple of bux . The NiCad battery pack was fried but everything else worked alright .

The RAD is a tracked unit that is capable of manouvers using a radio control TX on the 49MHZ surface / toy band . The other main feature of this robot is the operable arms which can pick objects off of the floor and lift them to about 14 inches high . The articulating torso does the lifting function .

The plan for this robot is to install the Arduino based modules that I constructed last year for operating in the house . Tested modules include a text-to-speech type voice synthesizer , FPV camera and VTX , 4 way ultrasonic distance sensors , various LED lighting and nav lasers . Ohter possible equipment may include a rudimentary LIDAR system modified from a working ultrasonic sensor board . I will have to use Java or Python to write a proper GUI as an overlay for operating from a laptop . The live TV picture would occupy most of the GUI with various instrumentation / telemetry values around its perimeter . Nothing really new here . My mate Donny will have to help out on the server and Inet stuff as I am an idiot in this area . Donny , however , is a genius with the I.T. stuff !

Check out these first destruction / construction pix of the early progress of the RAD's mods . Comments are welcome , as usual . I guess that I will be consulting the ROBOTIC section of this modeling website further to get some other ideas as well .

Gentlemen :

Knowing that I may receive some flak over this one , I decided to do it anyway . The work shop is in full winter mode right now . The firewood is in place and the little fridge in the shop is fully stocked with goodies . As I usually take my lunch in the shop , today's option was to try something a bit different in baked potatoes . Not an unusual choice for me during the winter days , but it was the first time for these this season .

As I was streaming the CFL Eastern final football game on the shop computer , I realized that those potatoes I threw in had to be retreived in about 45 minutes . I did not want to do a quick trip into town to BUY ? some tongs and opted to see what the metals scrap pile held instead . There was a nice piece of aluminum stock in that pile that could be quickly reworked to make a set of tongs . Got them finished just in time to get the potatoes out of the wood stove coals .
