As part of a build challenge that I participated in on the FT forums, I picked out the FT Tiny Trainer as one of my next builds. So here is the intro video to the FT Tiny Trainer. The FT Tiny Trainer is a versatile plane that can be used as a chuck glider or RC. It also has the ability to grow with the ability of the pilot by offering a polyhedral glider wing and a separate sport wing with ailerons. So you can go from 3 channel to 4 channel just by changing the wing. I'm going to start doing the plane as a 3 channel and see how it does.

Like most things CANbus Ardupilot is a little behind the game. We have come a long way on this project from setting up power, installing the ESC's, adding GPS and Mag, getting information from the Notify display and adding the rangefinder for more accurate altitude measurements. The SLCAN tool and the UAVCAN GUI software has given us a great way to monitor data on the CANbus and configure our can devices and troubleshoot. It still allows us to troubleshoot those devices even buttoned up inside the multirotor. We get an unprecedented view of what is going on inside the quad in real time instead of waiting until the flight is over to review the logs. With UC4H we know what the rpm of the motors are and what the temperature of the ESC's is at. We know how many satellites we have locked and that the EKF2 as initialized as examples.



But some of use grew up using Mission Planner and with all the benefits of UAVCAN GUI it would be nice to integrate Mission Planner and UAVCAN. So OlliW developed a way of linking Mission Planner to the CANBus and allow us to connect with CAN devices on our multirotor just like connecting to the flight controller and downloading the parameters. With the UC4H Mavlink Bridge we can get our CANbus information right in the Parameters with all the other aspects of the flight controller we configure.

The UC4H Mavlink Bridge sits on the CANbus and connects to the Pixhawk via a serial connection. It is created using our multipurpose General Node. So simple and so powerful.

EDIT 7/3/19
After a few flights I found that with the Eagle mounted so close to the nose on the pan servo it was very disorienting under head tracker control since I had no center reference. I also found that it kinda ruined the HD footage with it right in front so I removed the pan servo and mounted the cam in the foam - much better!


EDIT 3/28/19
A few items I didn't mention in the original post and my final AUW:
1) Current AUW is 4063gr. with a Turnigy 10k 12-24C 6S and 3995gr with a (no longer available) Multistar 10k 10C 6S
2) I used, for the first time, Goop hinges. They are MUCH more flexible than my usual "Z" hinge and tape or lam and I could not tear them off when I tried.
3) On my previous Drak Builds I have used a double layer of 5mil lam on the bottom and even that get's torn up from landings on the rough ground where I fly. For this build I went with 2 light coats of Goop. It remains to be seen if that is more effective...
4) With my new idea of putting the Vtx in the SIDE of the nose, rather than in the top, I discovered that in bench testing the large heat sink got HOT after 10-15 minutes. I didn't have this issue on other planes with the heat sink facing up and since I often will be powered up for 10-15 minutes while waiting for sat lock, calibrating the tracker, and general BS I decided to add a fan. I have several that come with my Hobbywing ESCs that I don't use. I cut a hole in the Main Bay corro and glued the fan to the underside and

I flew this guy several years ago. The engine would not idle and it was a bit of a pain. Recently I ran about a half gallon of fuel through the engine, trying to get it more broken in, It idles a little lower, but not enough. And it dies when idling. PITA. So I just started it on the runway and let it go from there. Flys really nicely and the motor does sound really good.

Order has been restored to the universe {at least in my hanger}

The day started with a inch or two of snow and temps around 25 but with bright sunshine and wind still 20 mph gusting to 30 .
I waited for the sun to raise the temps and melt the snow,they predicted 30's by early afternoon.

So out I went with my trusty glider retrieval system { old collapsible pool net handle ,a section from my roof snow rake ,a old coat hanger and of course duct tape }...".Remember guy's if you cannot be handsome you might as well be handy".....
might as well bring the Swift back out as well since I am going to walk back up the hill anyway.

I wondered if the wind might have blown it down but there she was where I "left her" still in the top of the tree on the back side no worse from the wear of a stormy night in the elements .
I taped the sections of handle together and the coat hanger as a hook at the top ,maneuvered it thru the brush and tree limbs and with a little shake and tug on the limbs down she came ,right into my hands .
I was tempted to try to fly her again but decided not to push my luck {when i got home I plunged the battery back in and everything is working fine }
Once back up on top of the hill {after a bit of a rest } I flew the Swift for around a hour,packed up and headed back down the hill and home.
A Good day !

BTW - I remembered that last year the wind following a Noreaster behaved the same way,
first day great wind but also snow/rain or mix
Next day great wind Sunshine and dry -
Keep them in the air Boy's !

I got in another flight of the DC-3 today and included the usual video where the plane takes off, vanishes, camera moves around, plane jumps into view as it lands. It flies very smoothly now. I've kept the CG at 40mm and end up spending most of the flight at half throttle.
The C-47 version is getting paint now and will soon be done. It's only going to get Park 180 motors, but they might be perfect.

Project - "Glue & Fly Series" Nano Backyard/Indoor Plane Status #1



Here is a link to the Video:
https://www.youtube.com/watch?v=l2Uc4sxtJyg

OK, I decided to take on this side project as I have wanted an Nano/Micro Backyard/Indoor Plane for quite some time and I wanted to be sure it could carry a Micro FPV System so I decided to try and design one myself ;-)

This is Ground Zero, my Prototype of what I envision for this Plane.
It's much smaller that I had in mind so I think some upward scaling will be in order ;-)
I have already build this Airfram 90% so I'm going to complete this build and perform the Maiden Launch as a learning process.
I stated "Maiden Launch" and not "Maiden Flight" because I do not expect this Prototype to actually fly or at least not fly well.
Stay tuned as I work my way to, hopefully, designing, building, and flying a well behaved Nano Backyard/Indoor Plane ;-)


See you in the Air!

Iím always amazed when I read on RCGroups, that some people donít belong to an R/C club! Now, I realize that people can live in an area where there just arenít any clubs within a reasonable driving distance from home. So I get that they fly solo. My advice to anyone that doesnít have a club nearby, is to try and start your own club. Put up posters in prominent locations around your area, shopping malls, hobby shops etc. Who knows, there may be others who, just like you, are looking for an r/c club to join. I also realize that some people prefer to fly alone! And thatís okay too!

For those of you that do belong to an r/c club, what do you get out of it? Why do you belong to a club? As I look around the room at each of our members I can analyze each oneís involvement. Some members are content to show up at our general meetings and interact with like minded individuals. We might not ever see them at the flying field, special workshops or other functions. On the other hand, we have members who are involved in all aspects of the club and we see them at the field quite often as well. Each members gets what they want and I am okay with that. Our own club of some 30 members, might only have 10 -12 pilots that actively fly on a regular basis.

Personally, I enjoy the camaraderie! The lively exchange of ideas, whether it be at a meeting, workshop or on the field. There is such an amazing collections of building and flying knowledge from the members who come from all...Continue Reading

1/24 Scale ECX Barrage Belt Drive Mod (2 min 40 sec)


Please Like and Subscribe!

This is a belt drive mod for the 1/24 scale ECX barrage. The stock truck lacks the torque and low speed control to crawl. The stock gear ratio is 5:1, this mod will make it 10:1. Besides the 3D printed parts you will need a few #12 rubber bands and two bearings that have an OD of 8mm an ID of 3mm and a thickness of 4mm. This does not require any permanent mods to the truck.

Hobby shop Bob my flying buddy , asked me to have a look at his 120 Magnum FS cause it wouldn't even fire let alone run . What a disaster , jammed valves , cam followers , ring , bearings were dreadful . Rust everywhere. Took ages to get apart , the gudgeon being the hardest to get out , I thought it would be the inner cam bearing as usual but came out quite well. Had to rebush both ends of the rod, make a new pin , grind the crank pin , re profile the cams grind the ends of the cam followers to clean up , reseat the valves after grinding the faces . Had to be careful with the valves when grinding them as the stems below the heads were well pitted with rust , but they seem quite strong so refitted them . The ring was stuck in the groove so soaked it in Chemcarb overnite and after a deal of fiddling I got it out with out breaking it , but made a new one anyway . Put it all together and it's a very nice engine now , runs and pulls very well , little worried about the carb as the barrel had a lot of rust type build up on it , but cleaned and polished and it does all the right things on the bench . Ugh , I've written all this and now I've lost most of the pics I took !!!!
