Calmato trainer 40
 

I want to replace my prop because while idle the plane is still moving forward. My prop is 12x6 as the manual recommends. Should i replace it with a 10x6 for example? Some opinions by some owners?

No, not if you're happy with the performance in the air. The prop is selected for what suits the airplane and engine in the air not on the ground.

Your idle might simply be set a little too high...

Exactly, the prop should make the plane fly how you want in the air. Do you like the way it flys?

If so, try adjusting your idle speed. If the plane still wants to roll when the idle speed is correct then maybe look at adding some friction to the wheels with something like fuel tubing between the wheel and collar. Be careful not to add too much resistance or you'll just create a new set of problems.
