I have a SupaPup Mk 4, folding wings.
I bought it initially with the intention of keeping it in a trailer as there was ZERO hanger space, hence folding wing requirement. When we got the plane to The Oaks we found that there was a spot in the hanger, useless to anyone else, that it would go in nicely, with the wings folded.
Actually folding/unfolding the wings is not really a problem, less than 5 min a wing plus about 2 minutes for the turtle deck.
There are 2 main problems with storage with folded wings.
1. With wings folded the tail is very heavy and can be difficult to manoeuvre. I have to negotiate a 90 degree turn into the hanger to get to my spot which can be difficult depending which other aircraft are in the hanger at the time. A full castering tailwheel would probably fix this problem.
2. Perhaps not a problem with other aircraft, the position of the fuel tank vents is such that you cannot fold the wings with more than about half tanks without it slopping out the vents. If you have significant fuel in the tanks you have to drop it before folding and put it back next time you get the plane out. Apart from the pain in the proverbial transferring fuel back and forth I prefer to keep tanks full to minimise condensation, which is not possible on this plane.
There was a post to these forums quite a while back, I can't find it so it may have been before Ian ported the site over, where someone was questioning the advisability of having wings that are designed to fold. I said then and I'll repeat here that I also had some reservations about an aircraft with folding wings but when you look at it, my SupaPup has 3 bolts holding the wing at the fuselage - mainspar, rear spar and the bottom of the strut, the clubs Lightwing that I also fly has the same 3 bolts holding the wing on. The only difference is that on the Pup the rear spar and strut bolts are in line so they act as a hinge when you pull out the mainspar bolt and on the Pup all the bolts are very easy to see when you do your daily, on the Lightwing they are buried in the wing.
Oh, if you're still worried about the mainspar bolt coming adrift in flight, I can see the bolt, nut, the R clip through the castellated nut and the mainspar where the bolt goes through all without moving my head more than about 50mm, I could even jam something on the bolt to stop it moving if the R clip and castellated nut came off in flight . In the Lightwing, the first indication of an in flight problem with one of the bolts would be the wing peeling off.
Getting wings off and back on can be fiddly on a plane not designed for it, in my opinion a plane designed with folding or removable wings is well worth it even if it's only on the off chance you might need it, unless off course it necessitates major compromises in other areas.
