I want to start a thread for the pixracer as a RACER.
My personal background: I started flying with a self-build APM aluminum - wood frame quadcopter (diameter about 70cm) about 5 years ago. Then moved on to small helis and larger (600class) helis with commercial fbl. For about a year and a half I am now flying 250 class quadcopter with naze32 on them. Pure acro through gates, through trees, around obstacles and abandoned houses with loopings, flips etc. Nothing like the big shots on youtube. I would say medium flyer.
Setup: ZMR250, 12a ESC with BLHELI 14.3, 1806 2300kv DYS Motors, 5040 DAL Props. Pure FPV flying. No LOS. This rig flew with the NAZE32 with betaflight just fine. Airmode was a dream.
No GPS, no OSD, no nothing. Just a pure racer
Changes: pixracer with the latest (from 11.2.16) px4 stack. ACSP4 underneath, but just as BEC for the pixracer. The esc are soldered on the diatone pdb. I didn´t want to change this. The wifi module on top.
Impressions and wishes in the next comments.
