I am new to the game and am learning on a electric glider and have built and flown an LT 40 with OS 46FX. I have a new in box OS 32 (older ball bearing model) that I would like to use on the LT and move the 46 to another plane. The LT trainer is supposed to fly with a .30 in it but I am concerned about the lighter weight affecting the balance since it is already tail heavy w/o added weight. Can the smaller engine be moved forward considerably to balance the plane? Will the .32 be enough for a trainer?
