Hi All,

Well now with a little over 40 hours on our Grey Headed 582 Model 2 Kitfox, I have most of the initial problems licked.

The scariest was full on wing flutter - YIKES! But that seems to have been taken care of by tightening all control linkages and shoulder bearings.

I am still having trouble with temperatures. Eliminating air leakage around the shrouded radiator and moving to distilled water seems to have helped sufficiently for days cooler than 85. But those days are becoming few here in central CA.

Anyone have experience with larger radiators for better water cooling?


Another issue is the tiny tail. The plane is squirrelly - but much more of an issue is losing sufficient elevator authority under 45 mph to comfortably push low speed landing performance.

Any suggestions for retrofitting larger rudder and elevator control surfaces?
