I must have had one of the early ones because with an OS 91 it needed a lot of nose weight even with a large airborne battery in the fuel tank compartment. I talked to Fai about this and I suggested that the wing should be moved forward if possible. Apparently something changed - maybe that was it. I'm glad I heard about the one-piece wing design on the Spot-On. I prefer 2-piece, plug-in wings so I guess I'll stay with the Groovy.
