For the last several months, I’ve been working on taking a 450 size TwinRex and converting it to fit a HUP retriever fuselage. This mostly involved extending the rear shaft to a greater height. I also fitted Blade 360 Trio heads and used the Rotormast V-22 Swashplates to allow for a 4-servo configuration with V-links.
Components:
Blade 360 Trio 3 blade heads
CopterX thin chord 325mm blades
Rotormast V-22 Swashplates
Garrt 1800kv motor
HobbyWing 60A ESC
2700mah 4S Battery
HC3SX FBL
Video of the first 2 flight below:
During these first 2 flights, I’ve experienced some issues as seen in the video. Multiple times now, I’ve seen a sudden drop in in power, accompanied by a yaw kick. In all cases, the motor was cool to the touch and seemed to work fine, ESC operation was also uninterrupted. I’m really not sure what’s been going on. I am also troubleshooting a building pitch vibration that’s begun building the last few runs. I will be doing some close inspections of the bearings and the gears to see what I can figure out. Any suggestions or feedback from those experienced with tandems is appreciated.
