build the sport wing and use even less dihedril(sp) if your building skills are up to it. use rubber bands as stated in the previous post but go ahead and install the provisions for the bolts now and they can be drilled later. be sure to check the wing incedence (it's not perfict out of the box). I've built 2 PT 40s this year!! one for my son and one for me. rubber bands saved his fuselage in the tall grass. I split my fuselage in a simular situation using bolts.
