FunMark HD

This is another iteration of my FunMark. I've basically removed LED's and analog vtx and replaced it with DJI O4 Pro. The GPS went from the back to the location above the camera (where the gopro mount used to seat). I've also used the Mark 5 O4 upgrade kit to be able to install the O4 Pro camera. Most likely, I'll replace currently used Gemfan 5042 props with HQ R36.
Motors I use are 2450kV version.

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..
