RE: Venus II
Hobbico reccomends 13x8, 13x9
I am using a 13x9 on a Lttle Tni right now and not sure i'm happy with that.
the manual calls for 14x8~10.
with a 14x10 APC I got 8500 rpm, a bit on the low side for that engine.
If i were doing it for the Venus i would start with 14x8 myself.
Clearance is not problem with a 14 inch prop as I am using a 15x10 on my Venus with no problems at all. (os ax120)
