Prop Question
 

I'm currently running a Saito 45 with an 11-6 prop I would like to switch to a 10" prop for more ground clearance but I'm not sure what pitch to use. Does anyone have any ideas?

Prop Question
 

Try a 10x7.

yup
 

Go down in diameter (1) and go up (1) in pitch
11x6, 10x7, 9x8 etc. :eek:

Whaddya flyin'?

Have fun-

Wrong!
 

If you want to retain the same propeller load on the engine, which as I understand is your basic question, you must add 2 to the pitch for each inch you subtract in diameter.

An 11x6 will be equal in load to a 10x8, or to a 12x4.

You can use the Reivers thrust calculator to demonstrate it to yourself. All three props will spin around the same RPM, on a given output (HP) level.
