hey guys i got a little fun fly plane thats got a 32 inch wingspan...

im at 6500MSL..

and have a 40 LA on the plane..

which prop would be the best for 3d/ fun fly flight?

10x4
11x4
or what should i get??

Felix

I don't know if an LA will pull an 11-4. If it does that would be ideal.

Andy

An LA .40 will pull an 11X4 just fine, (try a thin TopFlite wood) more so if you take out the baffle inside the muffler, and use 15% nitro.
These engines are not the little weakling a lot of people think they are, I've got one flying my 6 lb. Spacewalker II.

Doesn't that engine seem a bit too large for a 32-span plane? I'd guess something around .25 would be much more apt.
