It might be really good. What are You using for muffler- standard one or tuned??

Depends on the plane, if it's under 5 lbs AUW you're OK.

If you specified which plane it was, you would probably get more responses.

i am talking about giles 202 3d : http://www.chiefaircraft.com/cgi-bin...DGiles202.html

by the way, what prop should i use with this engine and this plane ?

Wow! that looks like a great deal- $99 bucks huh?

Based on the span and weight the MVVS-49 should give you awesome performance- if 3D is what you are going for, then I would recommend the 12x4 APC prop. Seems like a great combo there----

Keep us posted!
