RE: OS 140 RX...what prop?
I have tried the 18x12 and it's too much for the motor. I ran a 17x13 and it was my favorite until..................
15.5x12 4 blade. What great downline speed now. I have so much time in between manuevers. I'm running mine with a greve's pipe which give's it a little extra ummmpppphhh. I am going to try a 15x11 4 blade this weekend as I just got one to try from Central. I'm running magnum 1 fuel. I'll tach it with both blades this weekend. I love this motor, pipe, 4 blade combo.
