RE: GP RV-4 Engine Selection
i recently completed construction of my RV-4 and am very anxious and scared at the same time to fly it. haven't had too much luck with the take off part yet (can't keep them in a straight line)...landings are beautiful though. i also have the o.s. 40 FX and was curious if it is going to be enough power to do any nice stunts or just enough to keep it in the air for a nice days flying? also, how does it do as far as aerobatics? i'm not looking for mad 3D, but i would like to learn rolling harriers and torque rolls at about the most. i never saw a review on it 'til after i bought it and i don't like the tail on the cap. can't get into tricycle's though.[:'(]
