I have a WH 28% Edge and flew it somewhere around 100 flights last year and it shows no signs of fatigue. The only problem I had is the tabs on the hatch broke off a few times. I emailed Tom and he emailed me back with a fix for it. No problems since then. The landing gear is sturdier than on some of the other models also. I just love the way it flies.... Most of my other planes collected dust while the bunny collected flight time.... Bill
