over rev/run

[Bumpaous]

Last time I went out the motor sounded like it was over revving too high for the speed, any idea what to look at

Test with a new prop ?

 

[Bumpaous]

Is there a way to test the prop that's on there now because those are kinda spendy if that's not what it is

 

[racerone]

Mark the prop and hub.----Test run.----See if marks have moved.-----I do not believe a prop is a " spendy " item.

Thanks I'll try that, and so if it has then it would be a bad prop correct ?
