yep 2 failsafes using the tbs crossfire, Still not sure what the cause was since it happened on two diff rigs, and also my buddy corndog had one as well. Fpv signal never went out, But zero damage done to either copter except a antenna getting knocked off, most this video was made with the mb epic 2299 v2 with 2207 2450kv primos, 5552 gemfans 5s, and the mb epic 262 v2 2208 2350kv primos 5s and dal tj 6.45 tri props, both rigs running betaflight 3.2.5
