Have had my GB-Y for over a year and have maybe 30 flights. Only problem I had was the gear mounting blocks were very open grain mahogany and very thin. I replaced with thicker machined poplar slotted to lock over ribs, epoxyed in place and haven't had any problems since. Easy to fly plane, I use Saito 180 and classic Master Airscrew prop, the combo seems OK by me....... Covering is a little thin, like econo-kote. I would have prefered Ora cover or Ultra cote.
