Foamy

Here's my bumper build. It's not light at ~125g AUW w/ a 650mAh 2s, but it lets me fly inside when the weather is bad and it is basically indestructible. I think I'm going to order some 450mAh 3s because the hover point is somewhere around 60% throttle. I'm getting 2 minute flight times on 2s, but it just feels weird being at the top of the throttle all the time.

Notes:
7000kV motors
I designed a custom battery strap bracket that worked out nicely. Here's a link: https://www.thingiverse.com/thing:2452224

I designed a little bracket for it. I'll put it on Thingiverse later this morning.

Build a 5" Long Range Drone - Transformer Ultralight

Mar 04, 2021

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..
