So back in early 2017 I bought a STORM Bumper 3 from HeliPal. Who knows that almost 4 years later, ductless Cinewhoops have come back into fashion?

Some discussion on parts used

Motors: Flashhobby (DYS) 2004 3150kv
It's 2021 and hopefully no one is on 1408 motors for their cinewhoops anymore. 20xx-22xx sized pancake motors are similar in weight and stator volume yet offer dramatically increased torque and efficiency for swinging heavy 3 inch props. The only thing you give up is top end speed which is not really an issue for a cruising cinewhoop, anyway.

Frame: STORM Bumper 3
No ducts, just guards to protect the propellers, greatly decreases drag and makes this thing more like an overweight micro quad than a cinewhoop to fly. Furthermore, I love how this frame was designed in 2017 yet has many features that are still considered useful today - dual 20x20 stack mounting, ample space, battery strap holder, antenna holder, space for capacitor, etc

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..
