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 may try a mixed setup of 6" bi-blades in the front and 5" tri-blades in the back, because Y Knot?

Some basic around the house flight video below. 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!

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)

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum. I've never built such a plug-in-play quad! The flight controller has an integrated VTX and doesn't..
