I have an OS50 Hyper in a Caliber 5 and I am using a Futaba 9C. I set the end points to match the throw of the carb horn.
I can't get it to idle until I raise the bottom number on the throttle curve to 45. That is almost half way! I have the servo horn and the carb horn parallel with each other at half stick so they move together. I also tried to adjust it with the sub trim. No matter what I try it won't idle unless the throttle curve starts at 45. That only leaves me 46 to 100 for entire curve.
How do I get it to idle at a lower setting on the curve?
