This is an iteration of my 4 inch Twig Mutant with air unit. Wanted to have onboard recording and currently not switching to dji o3. I like 4 inch because it´s fast enough for the places i fly in, fits all electronics i want and it´s half the weight of a 5 inch freestyler. The true X with battery on bottom has a very small formfactor for a 4 inch, too! Plus the batteries are much cheaper - love it!
Since there was no one who fits the full air unit into a twig mutant, i had to design my own canopy. It´s devided in two parts to have access to the FC and to fit the air unit in. Maybe i´ll figure out how to integrate a place for the xt30 into the 3d print some day.
Motors are Betafpv 1506, 3000kV. They feel nice but a bit higher kV could make it a bit more aggressive on the throttle.
Flies on tattoo 750mAh 4S. Dry weight is 190g, with battery 280g.

i am looking at making a toothick 4 inch as well. not with DJI stuff but with walksnail. i already have a 3 inch toothpick that rips. was wondering how this is flying. i was looking at 1604 motors 3800kv. what flight time and does this feel like a boat or a racer?
Hi, of course it´s in between these two extremes. I think it has plenty of power to catch after dives and to freestyle it. I think your motor choice should be totally fine! The walksnail vtx is much lighter than the full airunit. I fly it on 2-bladed props and even with that it´s nimble enough for me. I´m getting around 4 mins with cruising / freestyle on 750mah 4s. I wouldn´t go much bigger on the motors on that frame.

i am getting them to make a unibody design of this frame, also i will be using the 1s walksnail vtx just like on my 3 inch.
Super clean! Would love it if you you could please share the file to print the canopy off! I have this frame lying around and would love to build it.
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..

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..
