The Y Knot

Well I built a Flynoceros Y Knot! This thing looked awesome on the Flyno site and is even cooler in person! I'm still tuning a bit but after lowering the stock Betaflight 3.5.6 PIDs and adding a notch filter it flies pretty good with the 6" Gemfan props. The 6" props come very close to the ground in the rear so I have tried a mixed setup of 6" bi-blades in the front and 5" tri-blades in the back, because Y Knot?

The SpeedyBee Bluetooth adapter seems awesome as I can change any settings by just disarming and opening the phone app!

From my 1500mAh 100C batteries I was able to hit over 140 amps. My flights range from 7 minutes to about 4 minutes depending on the throttle. Could probably fly longer if I flew nicer.

This was a fun build and it turned out great!

One mile out and back flight:

Some max amperage information:
110 amps mixed (Gemfan Flash 6042 front and Gemfan Flash 5152-S Props rear)

108 amps 5" only tri-blades (Gemfan Flash 5152-S Props)

136 amps 6" only bi-blades (Gemfan Flash 6042)

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..
