This is the least favorite frame design I have encountered in a long time. There is this delicate balancing act you will need to do if you plan on building this thing in any normal way. The FC screws are recessed between the arms and there are no tool openings. This means you either need to somehow build your stack before you put the arms on, or you need to install the stack hardware and assemble the frame then solder everything up and hope you can get it all tightened up without access to the bottom of the bolts. Just not my favorite, I like access to all the components without a lot of fiddling.

Once built, the build has been really fun. I started out with some 2004s and they were just too heavy for what they were putting out. I ended up with these 1404 3800kv motors and am pretty happy with this setup. I might try a smaller action cam to see if that gives it a little more oomph. EIther way, a fun rig to fly.

Do you remember what length screws you used for the stack and where you bought? The ones that came with the frame are too short.

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..
