Atom Mini 83 - Sub 100g 3s [RETIRED]

Crashed the sh** out of the FliteTest Gremlin; broke a motor and the frame. Bought the Atom frame with the thought to transplant the electronics.

Emax props were too big for the Atom83 and smaller props don't fit the proprietary Emax bullsh** mounting pattern. I could have cut down the Emax props but I'm lazy.

Weight w/o Battery: 52g
AUW: 94g

Super impressive weight! Seems like you may get thrust to weight ratios similar to much bigger mini quads? How does it feel?

Btw, seems like you listed a vrx instead of a camera and vtx?

The batteries in particular were a weak point of this build and I wish I'd used higher KV motors, as the 5400kv didn't give me the power I was looking for. This quad has been gutted and parts have been used elsewhere.

The links seem to change occasionally on this site, not sure why. I've updated it.

Which links changed? That shouldn't be happening. I'll look into it.

How did you wire the femto to the 4 in 1 esc

LawnDart   Aug 12, 2017 

The 4in1 has a breakout cable. The wires from that are soldered directly to the FC. If you look at the FT Gremlin build I have, there is a wiring diagram that shows how to wire it up. Motor 4 has to be remapped to a different spot. There is info on how to do that on that build page.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. 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..
