The YS 120 is also an excellent choice! Probably the best b/c it is as powerful as the Saito 150, but lighter, and much lighter than the 1.80. Not to mention the incredible throttle responce! I'm working on an idea to make the YS smoke without adding any weight other than the smoke tank! What a site this plane is when its in the air!

Hmmm... Soft mounting the motor mount? Would that be good or bad in this plane?
