I am not even close to flying mine, but I learned a few things that some of you may find helpful.

First, forget about my last posting on the Robart fill valve. It seems that you cannot use it like a regular tire filler. The needle valve must be "seated" deep into the tube. You have to use the adaptor and the small air line to fill the system. A freind of mine showed me how to modify a 12 volt tire compressor to work. This has to be much easier than using the Robart hand pump.

Second, is the Robart tail wheel retract mechanism. I was having problems with retracting the gear. The weight of the plane pushed the wire gear up. This interferred with the lever/toggle system of the retract. I solved this by grinding another flat spot on the wire and putting a small wheel collar under the mechanism.

Am I the only one having these problems?
