I have a LT-40, and it is a very very docile aircraft. Maybe a little too docile, but it is a great trainer! Want to make it a bit less docile? Remove the tricycle gear and convert it to a taildragger (there is a thread on here somwhere that deals with this mod), hang a Saito .56 on the nose swinging an 11x7 prop, change up the CG, and this docile trainer can spice things up a little. I saw one modified like this last weekend, and it was pretty cool. Granted, it wont burn up the skys, or win any aerobatics contests, but it WILL get rid of the image of the LT-40 being TOO docile!
