Thanks for the reply Frank

I know that a will need a new mount I will be using a great planes adjustable mount thats not really a big problem is not the first time i put a bigger than the recomended size engine in a plane(I build planes for a friend) but thanks for the advice.

I see that you are at a high altitud but I am nearly at sea level (100 or 150 meters) so i don't think i need as much power as you to 3D but I want to have a better performance than my actual 3D bird buecause it is to heavy (2 small hits and 1 hard crash) so i don't have the performance I like to go DOD so i want more power in the Showtime to have enough pull out to feel comfortable when i am doing low hovers, hariers, etc.

Do you guys think I am going to big with a Saito 115? or should I stay with a 100?
