Don't feel duped. The Robart gear for the GB are quality and I would recommend them to anybody with confidence. It is inconvenient that the stock wheels don't fit, though. 4" Dubro Treaded Lite Wheels wheels may fit http://www3.towerhobbies.com/cgi-bin...?&I=LXD783&P=C . The Dubro wheels are a tiny bit narrower, but if they are too square, they will rub the same as the stock wheels do. I did sand down the stock GB wheels to get them to fit in. I may have fitted in a tight fitting drill bit or dowel (I don't remember which) and chucked it up in my drill. The foam rubber doesn't sand easily but I found that coarse grits worked better than fine. I didn't try anything coarser than 80 grit, but I'd suspect coarser is better.

If I remember correctly, the trick to reaching the pin is to install the fork without the wheel. It has been a while since I have used the stock Robart setup, so I could be wrong about that. I would recommend that you use my "non-stock" setup for the Robart gear that allows the pants to telescope with the gear. Telescoping pants eliminates any possibility of them contacting the ground when the gear bottoms out on a hard landing. The real GB and all planes that have wheel pants (Stuka etc.) had telescoping pants for the same reason I'm sure. They are not too difficult to do either. If you have any questions that are not covered in the below thread, let me know. (PS. the first video in the thread was lost when RCU's video site crashed. It was just a closeup of the finished setup in action)
