Greetings Frank,

I also fly a CH601XL. It is hangared at KBRG (Belen). I would be interested in communicating with you on a variety of issues surrounding our planes. My email address is wolfcub1945@gmail.com/

Frank, check rigging first.  Next my issue was when I built it I did a difference of about 5MM on one wing.  Builder error.  I called Roger and he basically said fly the plane it will be fine.  I do have a very heavy left wing and first flight my arm hurt for days.   Checking rigging helped and after much research I found a video about heavy wings.  As our planes have a "radiused " trailing edge you need to lightly squeeze the trailing edge of the light wing.  Do a small amount at a time and test fly.  Took me two squeezes to make it right.  Now I can trim it hands off unless I fly with one tank near empty.  You are not flatting the trailing edge, just reducing the radius.
