Custom True X Floss

I wanted an ultralight true x like the Minimalist from Armattan, but I wasn't in love with the arm design, so I got creative. I made a custom bottom plate for some spare floss arms I had laying around and this is what I ended up with. The Kakute is perfect for hard mounting because the IMU is soft mounted on top of the board, and I got it for free (prototype version). Could shed some serious grams if I went with a micro cam and tpu mounts, but I had this camera laying around too. At ~250g it should be pretty nimble with those 2205 2555kv Brother Hobby motors. I'm really liking the form factor of the Spedix escs. Also, this design is perfect for the Runcam Split because the camera is high enough above the props that you don't see them. Thanks for looking!

Ive been contemplating doing this exact frame setup. Did you follow the qav ulx idea with plates above and below the arms or just like the original floss?

I just have one plate like the original floss.

was the plate hand cut or did you use CNC?

Hand cut, very carefully.

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..
