I have the modeltech J-3 25 and havent flown it yet though it is almost ready. I decided to get creative and am in the process of building functional shock landing gear out of the bent aluminum gear included with the plane, have only finished one shock and hope that it will give me some smooth easy landings. Anyway i love the plane but really know nothing about how it does in the air, hopefully i will find out this weekend. The pics I'm adding will give anyone interested some reference on how to build functional shocks for their cubs.
