Martian IV build with legacy parts from my realacc ultra 215.

This is my first 6" build and I'm super happy how it feels to fly and extra weight from hd cam doesn't seem to affect as much as it affects 5" quads.

Only thing I might change are the motors, but not because they're racerstars but because 2205 feels little too small for 6", maybe 2207 or 2306 would be better.
Graphene Square batteries fit nicely behind the camera, I really like the shape of these batteries.

Tried to practise 3D-flying with this thing.

I like your cap holder. I'm totally gonna steal it and adopt it to my next build, a Martian IV 220.

Go with 2207 with 6". I tried 2306 but I was not too happy about them. Depending on battery I would choose around 2200kv on 4s/5s or something around 1800kv for 5s/6s.

Yeah my next 6" build will be with 2207 motors for sure.

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..
