I have to say I really enjoyed this airframe albeit very slippery! I also heard of the Rev Pro's fuselages cracking right at the wing t/e hence my earlier comment suggesting taking the crotch past this point which should introduce greater fuselage stability for only a couple of grammes of weight. I really want you to enjoy this airframe and am only trying to extend your pleasurable experience, not bashing or anything ,I'm past that long since and recovered from the insults fired at me by a certain company owner

Hope the link helps you somewhat!
