I built this quad to prove I could build a 4 inch quad with a good size battery (4s 850mah) under 250grams. I originally bought an Avant Leggero loved the combination of the HQ 4X4.3X3V1S with 3600kv motors. I listed all the parts in a spreadsheet and looked for places to save weight. I heard good reviews of the RG motors, and they were only 14g each. I found working with the HGLRC XJB F428 stack a lot easier than most builds, the two boards have pins for power and signal. I went with the Grvdigr frame as it was 42g, I could have gone with another Avant frame, but the price was right, and it's Canadian. The Caddx F1 cam was a surprise how good it was, I originally put a Runcam MicroSwift but wanted to black out the frame.

I love it! I was able to get the same frame under 250g, but only because I used a 650mAh 3S pack. Super impressed! Love the Tombstone frames. :)

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..
