What motor are you planning upon installing? Also I think I'm going with 4 HS-5625mg servos in the wings and elevator/stab.
I thought about wing mods but it would be very extensive surgery beyond what I buy an ARF for. I know the Manufacturers read these forums as I've had several refer me to them in such regards as recommended engines etc.... so it is good to provide feedback that would be appropriate to the manufacturer as well as people considering a purchase. I do have to say at this point I am quite pleased with what I received vs. the price I paid. I feel I received good value and then some. However, a wing mod is something that I feel Sig /World should strongly consider. Something like the bottom fairing attached to one wing, two bolts through front into joiner, rear alignment pin etc... though a standard fuse with plug in wings would have been best, I think, on a plane this size. Most likely the design is an all out effort to keep it as light as possible. The wheel pants were probably off the shelf and are still ugly, I'm not going to bother trying to dress them up. When/if they break I'll get some cool ones or fab some up.
Most Sig kits/ARF's are very stout and hence heavy designs but in looking at this one closely they have really gone the mile and lightened this one up. even the shear webs in the wings have holes. That is why I'm hesitant to go the 180 route, even with the obvious advantages of a bigger diameter prop. Anybody have one of these in the air yet? Anybody from Sig reading this?
