I can tell you exactly what expect, I have one with an original JC Rabbit that puts out 19lbs. Plane came is a just over 22 lbs. We have 700' of grass and with 15 degrees of flap and I seldom take 1/2 the runway to get up. Just got back from Louisiana Jets and it got off in about 150' from asphalt. I have Pro-Link trailing link struts from Dreamworks, they do a great job of absorbing the bumps.
