Hi! What KV did you choose for the motors? Btw 5400, 6500 and 7000? With 3s battery, 6500 is too high in your opinion?

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..
