in theory, i think virtually unlimited. however, frame period (and response to a channel change) increases proportionally with the number of channels.

Re: Tricopter servo interfering with ppm signal

I have a similar problem (channels jittering) with that servo as well. My Rx is the frsky 4ch that is set up in cppm mode. Added a choke and I think the situation improved somewhat but still not good.

Changed the servo to a different type and it is well after that.

Re: Crius SE board does not register outputs or D8/D12 input

the fact that you are not getting consistent behaviour of your ide is quite a problem.

you don't need the board to be located at the frame geometric center or center of gravity.

perhaps the best approach now is to find a working setup local to you and compare notes.

for your debug2 problem, it may be the case that you are not using matching versions of the firmware and the gui. they need to match, otherwise the gui is misinterpreting the telemetry data coming from the crius.
