Hi everybody,
I decided to build the slowing modification that Hai-Lee posted here: Looking for a slow, Park flyer FT build and figured I would catalog my experiences and share them, since this is the first time I've gone outside the bounds of the "standard" FT plans.
Started with the PDF that Hai-Lee posted, just using the tip plans, and attached them to posterboard like SP0NZ described in an article:
I only used the tip plans, and made the center section by using the inner end of the tip plan and drawing those lines all the way across a sheet of foamboard. It was pretty easy to make, but was hilariously long, at least given the scale of the Tiny Trainer:
Next, for electronics, I used the following:
The fuselage is pretty much a stock Tiny Trainer, except that the motor sticks out a bit, and the shaft sticks out even further:
As a result, the CG is off (which you'll see in the video below). So, I moved the battery back and added tail weight (those lead sticker things):
Here's the whole thing hanging on my wall:
I haven't yet built landing gear, though I probably should. Here's a video of my maiden flight(s). I was alone, so the plane gets pretty small in the wide field of view, but it hopefully gets the idea across:
Things I want to try:
I've had fun with the project so far. It's a good learning experience.

Next, for electronics, I used the following:
- Racerstar BR2212 1400kV motor
- 8x4.3 Props
- EMAX BLHeli 30A ESC (plus a XT60 to XT30 adapter to work with my small battery)
- FlySky FS-IA6B receiver
- EMAX 6g servos
- 800mAh 2S lipo

Things I want to try:
- Put a 3S battery on it and remove tail weight, then reduce the max throttle to compensate for the battery, just to see how that changes things
- Figure out a way to either reduce the throws at higher throttle (that thing is *super* sensitive at non-cruising throttle, as you can see from my first takeoff)
- Figure out a way to compensate further for the higher torque of the bigger prop. It was noticeably easier to turn left than right. The motor is angled at the stock TT angle.
- Fly a lot more and see just how slow I can get it
I've had fun with the project so far. It's a good learning experience.
