volfy,
heh, tiny tim was already there, since the bird is used.

i didnt wieght emboth, but i think the engine is about 5-5 1/2 lbs,but im not positive. it was during summer that i had it off.

as far as vibration, it doesnt shake as bad as i thought it would for a single. mostly at low idle wil the tail shake some. wings dont shake too bad. ive seen patty wagstaffs shake more IMOHO...
i still want to try my MSC 25-10, but ive been too lazy to change props..

thanks ken, i was going to ask you eventually if i could cut the pipes for power, and how much, but wouldnt the noise go up too?
