Doppler by Rotaro, with the new Mjölnir 2308-2600KV motors. Beastly motors with loads of punch if you let them loose, but also very effective if you are.
The Kombini FC handles up to 5S, even if I dont.
I got the 6" version, running 5" props at the moment. Kit comes with some spare hardware aswell as a spare arm.

Flown this frame for a while as you can see by the pictures and it has handled all the beating I`ve been able to throw at it so far.

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..
