hey, im planning out a scratch build of a chipmunk that has a 80" wingspan, and i would like to run an electronic igniton in order to keep wieght down. what engine would be suitable for this plane? i would like it to be able to do aerobatics (not 3D, but good vertical would be preferable). i was thinking of using a homelite 33cc engine b/c ive heard they're quite powerful.
Is there any other engine i should consider?
thx,
andrew
