On first test it spun around like a top before lift-off, I had to change the yaw gyro setting from 100 to -100.
Also fitted a battery/camera tray underneath to serve as landing gear as well. Just a 4mm balsa sheet mounted with some 0.8mm welding wire and hot glue.
Weight without battery is 134 grams.
Changed the wire and glue to foam and hot glue mounts. Green led on back for orientation.
P/R 70, 100, 10, 20
Yaw 50, 20, 5, 10
S/L 60,50, 0
S/S 70, 70, 80, 90
My main aim was KISS as I am not a very skilled pilot with RC, having flown planes and gliders for 46 years. So here is my tricopter which is my second homebuild after a similar sized quad. FPV gear is really low resolution 5 GHz Fat Shark setup with the 433mHz pan tilt system removed.
Unfortunately my eyes are not so young so I don't think that even HD goggles would help, so this is just a dip into FPV for me.
The tricopter weighs only 278 grams with 1000mAh 3s battery and flies for 10 minutes on a charge.
