New AMAXinno motors in size 2207.5 with 2500kv are great, lightweight XBEE-SR 220mm frame, powerful T-Motor F55A Pro esc, reliable Matek F722-Mini flight controller - this drone is a beast! All components was chosen to handle up to 6s batteries without any issues, so to be sure that 6s batteries will do no harm decided to install bigger additional 50v 2200muf capacitor. Total weight with props is about 330 grams, so power to weight ratio is really mad!

Holly crap batman! 2500kv motors on 6s? Thats like 63,000 rpm theoreticly and at 330 grams it's got to a beast. I want to see a speed run.

I will add a link to flight video after testing this drone. Big question is to find propellers that won’t blow up in the air during a flight at a full speed...

Low pitch bi-blades? Thinking about it, I don't even know what i'd run. A lot of low pitch props are thin and would flatten out at that speed. I have a friend that built a Catalyst Merica running 2400kv 6s using a bolt v2, the bolt burned up on the third run.
He started out full throttle, it was fun to watch while it lasted but i'd start about 60% and put my amp draw right in the middle of my osd. Good luck, can't wait for the flight video.

Love the look of this thing, especially the stubby antenna for the VTX and how you've mounted it :D

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..
