Hello, it's my approach to build a TinyTrainer drone. I find out about this drone about year ago, but don't have acces to frame kit.
Now I buy ready to fly TinyTrainer from second hand.
I changed a few things to myself needs: AIO with better ESC 20A against 13A, receiver switched to TBS Tracer and camera mount with handler for insta360 Go1.
During rebuild I have to extend motor cables, to give some slack for AIO antivibration. Added bigger capacitor 470uF 35V, longer m2 stack screews and isolation between AIO and carbon frame. The hole in the frame has to small clearance for USB and neded small enlargement to prevent broke on crash.
Motors with 3800KV on 3S needs throttle about 50% to cruise and don't have much punch (even without additional weight), but I will try with 4S in future.
AIO is flashed with Betaflight 4.3.2 with bidirectional DShot and ESC with Bluejay 0.18 48kHz.
With Tattu R-Line 3S 550mAh flies about 4minutes with average agressive flying and battery ends with 3.8V per cell. AUW with this battery is about 170grams.
Flying with 3S have some advantages to give more time to find better trajectory and gives me another aspect of flying.
