Need help with my Servonaut SMT module

[Snochaser]

I'm not an expert on this Mario, but in my experience there needs to be a "neutral" position.... the horn is in the opposite position of the starting. My models are set to cycle the "cranking" then flip back to neutral and it starts...if it's not "centered" when you power it on then all bets are off.

I use a rotary switch to start all of mine, you may try it on another channel to get the feel for it, then switch to a joystick after. Hope this helps some.
