It could be. Piper1 just curious, are you using an aux channel where the ECU has you learn both the Throttle and the Aux channel in succession? versus single channel mode(Throttle and trim only).
I will say the Jetcat manual is not the greatest in this area of learn RC for single versus 2 channel. Kind of confusing since its in a couple different places in the manual. It deserves its own chapter or section really.
