An inch of elevator travel is a lot on a plane that size. My .40 size Cub is just barely over an inch of total throw, and it's over double the size. Does the manual have a recommended throw setting? I think you'll probably find that the plane is much more comfortable to fly down around 1/2 inch of total throw once it's trimmed to fly straight and level.

As for your motor, I'd call the manufacturer about that. If you have 100% throws set in the transmitter, you should get some prop movement at very low throttle settings.
