RE: 100cc engine choices
Tony this is largest plane I've had.I've had 2 33%s and 2 30%s and it's by far a lighter feeling aircraft than any of them.It does not feel heavy.Very responsive and stops and soon as you release the controls.It will do 3 point landings at a crawl without a hint of stalling.It is truly a fantastic flying plane.I haven't seen or flown a composite plane.They claim to be a couple LBS lighter but you won't be dissapointed with this.As far as cannisters,there is all kinds of room and I have 2 KS 70cc in mine with no problems with room.They sound absolutely awesome when you fly by yourself and roll.
P.S. I'm not a 3 D flyer yet but this plane will knife edge straight as the sky is long with very little rudder.
