Hey Guys,
The Tiny Trainer is my first RC plane and I cannot get it to fly like the youtube videos show. I'm running a speed build kit with stock power-pack A. My first 17 flights with this craft have been an absolute disaster and I don't even have enough information to make any intelligent next-step choices, and I don't know how to debug this. Here is what happened:
1. Launched the tiny trainer. It went nose down right away and destroyed the propeller
2. Replaced prop, pushed electronics toward the tail. After launch, it went straight down into the ground and destroyed the second propeller
3. Went to hobby store and replaced stock propeller with one slightly larger, a 7x5. Realizing it was probably nose-heavy, I velcroed the heavy hardware inside the body so nothing in there moves, I used better wing bands, I balanced the prop with a balancing device like David Windestal uses, and I balanced the CG until it was perfect. The next morning I launched it. It went really fast about 200 feet in a few seconds right into the woods and smashed apart against the dead trees. This is my best flight so far, and I tried at the very end before impact to control the craft away from the obstacles, but it behaved too wildly to avoid the disaster.
4. I had to rebuild the powerpod, so I did that, and the next morning at 5am, with zero wind, it went nose down immediately and smashed all the skewers and deformed the fuselage, despite the care I took balancing the craft.
5-12. At this point I just took off the motor and threw it around from a hill using the the control surfaces and trying to steer it. it doesn't seem to work very well. It crashed every time straight down.
13. rebuilt the craft from scratch using much more sturdy foam board. same flight characteristics, but it didn't break as badly.
14-17. same thing, crash every time nose down.
Should I add mass to the tail section???
