My favorite build yet. Runing the ImpulseRC Apex (Steele). Full Fettec stack (45a) running KISS. These KO motors are unbunbelievable, they use open cage bearings and require oil. Open cage bearings create less friction and heat (standard bearings are closed cage and use grease for lubrication). Crazy powerful and crazy smooth. After ripping HARD, these motors are still room temp. This build flies amazing, even on default kiss, just destroys any of my prior builds. 735g AUW with ImpulseRC Hero8 mount, Talon 1150mah and light weight hardware. 799g with BMC3D adjustable hero 8 mount, steel hardware and CNHL 1100mah.

I will upload some video ASAP!

Does the FETTec FC have an OSD or did you need a separate board for that?

I just ordered a set of these motors, did you have to purchase oil for the bearings seperate or did the motors come pre filled?

It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
