Setting up a 2Fiddy Ultralight with a 6s and some beefy motors (I just had extra supply :)), feels like a race quad toothpick.

  • Update one: Changed the standoff and some screws to teal, trying out the 4024 props and swapped to a TPU Mount for the 4+ antenna.

Nice! I've built 2 of these 4" versions on 6s so far. They are so damn much fun. I didn't even think about throwing a Nebula Pro Nano in there.. I guess it would be just about as good as any other 120fps cam. I also have a regular 5" 2fiddy built up too, but run 4.5" props on it, and it's just about as good as the 4" versions.

Those flow motors are the toughest 2004 motors availble. I bought 4 or 5 different 2004 motors and all of them were damaged way to easily. the NBD ones are great, but for 4" I use 1804s which are better for power to weight, and swapped my 5in 2Fiddys to 2104 or 2105.5s.

Have you tried the 4.5" props on your 5" 2fiddy? If not, you gotta try it out. Super fun!

I've tried quite a few props and motor combos on 4-5in 2fiddy frames. I find the Pb&j props the best for my preferences. Insane thrust and efficient cruising.

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..
