The Ford Flivver has walls that are extremely rigid. But! All was well gluing together the frame formers. And all was well gluing down the 1/64 thick plywood foward sides.

The 1/32 sides needed glue and all that wetness began to bow everything. It was so bad it popped the sides of two plywood cross-beams. And it kept on bowing. I went into action and pulled everything out of the middle except for the side formers.

I threw the sides on a Formica counter and starting piling on the heaviest books I owned. The side panels began flattening out under the weight. When I removed the books 15 hours later, the glue was dry and the sides were flat.

Too much drama.

I may have mentioned I picked up some bargains just before Christmas and the WLtoys A303 buggy was one of them .

Remote Distance: 50m
Type: RC Off-road Electric Car
Speed: About 35km/h
Charging Time: About 3 hours
Playing Time: 10mins
Car Battery: 6.4V 1000mAh Rechargeable Battery
Motor: 390 brushed motor
Brand: WLtoys
Material: Electronic components, Plastic, Metal
Remote Control: 2.4GHz Wireless Radio Control
Transmitter Power: 3 x 1.5V AA battery

The transmitter looks to be the same as the one bundled with the 12428 4x4 buggy from WLtoys .

The A303 is perhaps a little on the chunky side @ 938 Grams wet .

The A303 is almost as big as the 12428 ( Wheel base )

The 303 does sit a little low to the ground to be a true off road'er . I found the 303 was really dragging itself over the grass in our back yard . I would imagine this would really load up the motor / esc possibly creating heat and other issues . I would suggest this buggy might be ideal for flat dirt tracks / roads and such where the ground clearance would not be an issue .

I really like the turning circle on this one , much tighter than the 12428 . In fact I found it a little disconcerting at times as I over corrected ( having got used to the 12428 ) You can move the control rods so as to make steering less sensitive ( larger turning circle .

In fact there is a reasonable amount of tuning that can be done to the A303 to change its handling ( See Pictures )

I don't know that the A303 is in...Continue Reading

Happy Holidays! While staying over at my parent’s house in Cali during my Christmas Vacation, I received a wonderful Christmas present – the Eflite UMX P-51D BL Mustang. This is a perfect go-to UMX plane to keep at my parent’s place while vacationing so that I could have something to fly at their local grass park whenever I visit them. I had also brought my trusty Spektrum DX6 (now my secondary transmitter) on my trip to Cali, just in case flying RC during my vacation became an option. Here is the Maiden Flight of my new Eflite UMX P-51D BL Mustang.

Eflite UMX P-51D BL Mustang Maiden Flight - 2017 Cali Christmas Vacation Plane (2 min 57 sec)

I had challenged my Mom to record this on my iPhone 6. Please keep in mind that she does not know anything about RC and has never seen me fly an RC aircraft in person before, so recording this very small plane was very difficult for her (I actually had to edit out a good portion of the footage as at one point she had lost sight of the plane completely, lol). Overall, I think she did a wonderful job! And the Mustang (as most Mustangs do) flew beautifully and predictably out of the box with no surprises.. just a sweetheart of a plane, perfect for vacations. All recorded and edited during my Christmas Vacation with my iPhone 6, using the app Videoshop.

MODIFICATIONS:

1) Clear Tape Protective Film on Leading Edges of Main Wing, Nose Undercarriage, and Intake Undercarriage

TRANSMITTER, RECEIVER, & SETUP:

Transmitter: Spektrum DX6
Rates Used: 100%-Aileron / 0% Expo, 100%-Elevator / 3% Expo, 100%-Rudder, 0% Expo
Battery: E flite 280mAh 2S 7.4V 30C LiPo
Throttle Timer: 5 Minutes

ADDITIONAL INFO:

Camera: iPhone 6 at 1080P / 60 FPS

I have been an Amateur Radio operator, AL7AK, for a long time and I have done some really fun projects in HAM radio -Talking through an orbiting satellite, being part of a world wide contest station, and doing emergency tests in below zero remote locations in Alaska.

I have had the idea for a while to see if i could make an emergency VHF radio repeater drone. VHF handie talkies are used in emergencies for rescue coordination and aid delivery during disasters and HAM radio operators have a fine tradition of stepping up the plate during such events. For an active civic minded radio club it is not uncommon for them to provide for emergency backup power for their mountain top repeaters that allow the hand held radios to communicate over much farther range.

But disasters don't often conveniently happen in places where HAMs have prepared for such events and instead can happen in remote and difficult areas.

The idea behind this project is to see if I can build a tethered multirotor that can carry aloft an amateur radio emergency repeater that could be deployed anywhere and stay in the air for an extended period of time.

The problem with tethered multirotors is the current required to power a multirotor. A 6s octocopter can pull 20 amps or more and the power cable needed from the ground to the multirotor would be too big and heavy for the multirotor to lift. So most people solve this problem by feeding the multirotor with a higher voltage, which allows lower current for the...Continue Reading

so I've finished my chassis and have decided on the electronics for my build according to ecalc it should work however I was hoping some of you could give me your opinion ?
chassis weight 300g
propeller :size 6"
motors x4 : Multistar V spec 22205 2350KV 420w

ESC x4: Turnigy multistar 32bit 20A race spec 2~6s (opto)

receiver: comes with mode 2 controller hobby king 4 channel 2.4ghz Tx Rx v2

battery: multistar racer series 1600mah 3S 40c lipo pack

flight board: Matek PDB-XPW w current sensor 140A and BEC (5v and 12v)

in case your interested ill post a picture of my chassis here somewhere. Also I was wondering if ecalc add the weight of the parts themselves as you chose them as I entered in the weight of my chassis (300g). But I didn't include the weight of all my parts which in total is 700g approximately.
again any help at all would be much appreciated I think this will work but as it is my first time attempting to build a drone your feed back would be invaluable.

Review of EX1 from Eachine - Brushless GPS WIFI FPV With 1080P HD Camera RC Drone RTF Quadcopter



In great looking and compact box came EX1, my newest quad from Eachine. Never the less, the box was so small that it passed DHL customs process without any expenses. It was delivered to my door in very short time even holiday season is in full swing.

Quad feels nicely build, looks great with black glossy finish and there's no weird sound from motors etc. Quad and transmitter are small in size but transmitter feels nice in hand and I can fly it without strap.

My new VTX finally showed up. It took 18days to get from NJ to CO. What the heck, BG??? With this final component, I stripped her down and rebuilt it. The horrible horrible horrible FPV rig from Full Speed was yanked. So was the beeper. In went an Eachine VTX03, Foxeer Arrow Micro v2, a traditional button style beeper, and since I was in there anyways, I salvaged the 4-LED strip from my Eachine QX95 to help me with my LOS flying.

The cam was mounted into some new holes that I drilled forward of the existing cam holes. I gained about 1.5mm by scootching the camera forward. The power for the cam comes straight from the lipo, since it has a huge input voltage range. The VTX03 is powered from the original camera pads. The VTX lays down on top of the FC, and then the XM+ receiver lays down on top of the VTX.

The Delta IV heavy was a fascinating rocket, when it 1st came out. It looked like a classic giant movie spaceship when it lifted off & pitched over, revealing a row of 3 widely spaced engines. The space shuttle & Ariane 5 didn't look like classic movie spaceships, because they were obscured by solid rocket exhaust or mostly seen with just center engines after booster separation.


The Delta IV heavy never achieved its goal of economic, scalable capacity. Rather than repurposing the same cheap cores from smaller rockets, it probably matched SpaceX's experience of having to completely redesign the center core just for a handful of missions. Hopefully, making the boosters reusable will achieve better results.


Falcon Heavy will look even more massive when it pitches over. 27 engines making a rectangle of light will look like the rear end of a battlestar or a star destroyer only seen in movies until now. Then, when the side boosters separate & the opposing plumes of 3 engine burns interact, it should be a spectacular airshow.


Despite not coming close to the size of the rockets we once had, these triple core rockets are somewhat fascinating because of the potential to be affordable.

Synergy is a unique plane, and my long search for a good enough 3-views to start modeling and building was not successful. I finally was able to get a very good one (Special thanks to John, hope he reads this one day!) and the uniqueness of this one put everything else on hold (Sorry BV-208!).

Not the easiest thing to model but hey, that will only make it more fun!

I think I mentioned I picked up some Bargains before Christmas ( The last of them came today ) ..
One of those bargains was a WL Toys A303 Buggy .. ( We are talking bargain )

Anyhow , the battery does appear to be a 2s 3.3v per cell ( Life ? ) ..
Well , there is no balance lead .. And checking after installing said balance lead , yeah ! There is a need for it ...

A) I unwrapped the battery just enough to expose the contacts ..
B) With your Multi Meter find the contact for the back or front of the batteries where they are joined for series .. On the MM this will show the individual voltage of each cell
C) Once you find the contact for the middle wire , solder in your balance lead
D) Make sure your solder joints are good
E) Re wrap the battery

I really like balance charging ( really I do ) . Not doing so can lead to all sorts of possible issues ..


Its not hard ! Positive and negative contacts are already a given .. Simply solder your Balance lead wires to these contacts ...
What is just a fraction challenging is finding a contact point for the series connection . ( Thats why you own a Multi Meter ? - Right ? )
So there you have it , another bush league mod !

2s Balance lead :

A lot of these have a black wire in the middle and a yellow wire on the outside ...
Just remember the middle wire goes to where the battery pack is connected in series ( no mater its color ) and the outside wires go to positive and negative where your power lead is connected . ( At least they use Red for the positive wire )
