I won a set of T-motor F40III 2750kv 'Lets Champion' special edition motors, and picked up an X-hover Win5 from a friend who got it on a quad box boost. I literally tore the insides out of my other Racer X build because I wanted to see how these fly. so FC/VTX/Receiver combo just got hot swapped. I'll add details below.

Edit 1: I've had the maiden flights + 4 batteries of a pid tune session, and in my opinion this prop/motor combo does work. it feels aaaaalmost as tight in corners as triblade cyclones but you really have to rev the throttle up a ton to keep a tight corner. not a super difficult motor to tune, but according to miniquadtestbench they also test closer to a true 2600. the emax 2750kv were a bitch to tune by comparison. having flown and tuned both I would take these any day. as an added bonus, these motors stay veeeery cool. I would call them luke warm after a full pack with a good pid tune. even when they had bad oscillations they were cool to the touch. All in all a solid motor.

I'm not sure this prop combo is for me. Might try a slightly lower pitch. it's fast enough staying below 80% throttle the entire flight.

final note: these motors are not soft mounted, but FC is. it was impossible to tune the emax without soft mounting motors.

edit: testing micro cam on here with TPU mounts, also added TPU gopro mount. surprisingly ESC did not burst into flames with this setup.
