I am trying to set up my classic trex fiberglass heli to get extra options stabilize and loiter mode. It is very useful when mosquito attack or some unexpected visitors come when You are in the air
Matek f405-std FC
Futaba T8J with oryginal futaba s-bus receiver
So in my setup on the Futaba radio channels are as follows:
1 - roll
2 - pitch
3 - engine
4 - yaw, tail control
5 - gyro sensitivity - this one is connected directly omitting FC
6 - collective pitch
7 - unused for now
8 - arming
so my parameters are:
According to the manual with this settings RSC shoud take engine value from engine_interlock which is set to channel 3 and passhtru to ESC. Unfortunately my heli doesn’t turn engine on. When I set RCIN3 as function for engine control then it works, but I know it is not correct way for auto modes. FC is arming when I press switch and no errors are shown.
It is also a bit confusing for me, that arducopter seams to expect to have constant rpm on rotor, while in my manual setup my rpm is controlled by channel 3 according to flight mode: normal, idle1, idle2 and throttle stick position. I would like to leave it this way, but ardu manual says that for automatic altitude hold RSC_MODE cannot be set to passthru. It can be set to follow collective pitch, but this wont do the job as in idle 1 for the same collective pitch I have different rpm than in idle2.
My goal is to preserve acro capability of my heli when it was fully manual (without FC) and to add loiter or stabilize option as an extra feature. Nothing more
Can anyone help with engine throttle issue?
I have seen movies about configuration and so on, but can’t figure it out in my case.
My config is:
