This little guy I must say is simply a flying powerhouse. Now that it is winter I sit inside and fly it FPV around my trees in front yard. Simply a flying blast. To get it flying at its absolute finest there were several routes I had to take in order to accomplish this. First off, applying Betaflight 3.2 was an improvement until I got hot motors when using Dynamic Filtering, which I have working on all my builds with great results. Four things I done to eliminate the hot motor issue. First, soft mount motors, next was to get rid of the VTX mounted directly on top of the F3 flight controller. Not good. In order to separate the VTX from flight controller a 3d print was made to apply the VTX. The next thing was to reduce the height of the stack now that it was too high. In order to accomplish this while soft mounting the flight controller, all eight standoffs had to be modified. They were shortened by approximately 2 mm. Once all this was done, took it out for a test flight without hot motors, now it simply scoots when the throttle is applied. No messing around getting around those trees now. Flies incredible, almost like my 5" builds. Thanks for looking at my build.

Been messing around with the Betaflight tunes, was not getting that locked in precision feel on the sticks. I adjusted the SetPoint Weight to .05 and whoa what a difference it made. Simply incredilble, now I can fly at speed merely inches off the ground with ease. No oscillations whatsoever. Flies nearly perfect. I loved this 120 mm racer so much I built another with two backup frames just in case. Using a 3s 70c 650 mAh battery easily get 6 mins of hard flying flight times. Extremely efficient setup
