RE: Clipping LT-40 Wings
I clipped a single bay off each panel on an LT-40 after an accident damaged a wing tip. I didn't like the way it flew afterward, much to my surprise. While it did make it easier to land, it lost the effortlessness of flight in simple acrobatics. Where the stock version could easily do outside loops, it struggled with less wing area.
My suggestion is to move the CG to the back of the position shown on the plans, crank up the throws, and put on a large diameter low pitch prop. You can also decrease the decalage (wing incidence and down thrust), but re-balancing it gains the most bang for the effort.
