Tram? Whaddayoudoin'here?(I won't tell anyone...) Mine is bone-stock, except for the Fox .40 on the nose. The structure can definitely handle the extra weight and power. Were I to build another LT-25, here's what I'd do:

-Build the wing flat--no dihedral
-Set up the ailerons to allow 45* of throw(I've maxed out the throws as built stock at both horns and it still rolls too slow for me)
-Enlarge the rudder about 20%
-Install a good .40BB 2-stroke or a .50 class 4-stroke

It's a great plane built stock, but it's so forgiving i wind up fighting it a lot, so my goals are to neutralize it a little and speed up the reponse. I suppose if you made the modifications listed above, you'd have something resembling a kit-built .40 ultra stick. Maybe that's what you're looking for, maybe not.
