I am finishing up a Mig 29 from Top Gun (www.TGAJETS.com). I am not sure of its exact scale (it has a wingspan of 53" and a length of 76"). I am also using their scale struts for the retracts. Their retract setup is very good (the nose wheel has dual wheels), but I do not believe the mains are exactly scale (in the full scale Mig 29's, I am pretty sure that the main wheels rotate flat/90 degrees just before they retract into the fuse). I hope that helps. Bob
