Default Shrike .10 with OS .15CVA. Need perfect prop.

Any suggestions for propellors with this engine would be appreciated. I"m currently running a MAS 8x6. Please share your reasoning behind your suggestion as well. Thank You.

APC 7x6 or 7x7. I think APC is a more efficient and better suited for speed applications, than MAS. 8x6 seems too big for a 15. What are your rpm's? I participate in local pylon racing with la 15's, and the common props are APC 7x6 sport, APC 6.5x6.5 pylon, and Graupner 7x7 CAM Speed (a nice but obscure prop). Paul

John I flew my shrike 10 las weekend and have the same engine on mine - I was flying a 7x5 MAS on it because it was about all I had in the right range. I was running 20% fuel on a cool day.

Wasn't able to tach it, but it seemed a little under propped, I'm planning on experimenting with a APC 7x5 , 7x6, and 7x7 see what pulls it around the best.

I'll give you a lead on CF props, STEVE WILK at ELIMINATOR PROPS. Do a GOOGLE. Something in the 6x8 range should get that thing moving.
