Hi DP, yep, I am interested if it doesn't work out for you. Not sure how much I will really gain from that change because you will still need to add some kind of wood plugs into the tube so you can properly secure the stabs, and CF alone doesn't provide enough meat for threading and screws.
All my weights listed is everything out of the box. Nothing was omitted in the weighing process, so this is my baseline.

Anyone have a preference for a company that supplies the CF wing tube? Has anyone replaced the main L/G yet? If so, where did you get it?
Regarding a rudder pull-pull, could you use ChipHyde horns (1") on both sides of the rudder, or would a Dubro system be better?
