DB the saito 150 will be a fine engine, the ys 120 is just my preference for a plane that you may spend some money on. if you were to run the 6965's all around i would be putting at least a 6v 1400mah nicd or nimh in,it is you choice on what type you use in the end OR you could put a 2600 mah lithium in and fly all day with a constant 6v powering your radio gear with the added benefit of being lighter than the nicd or nimh[X(][X(][X(][X(].

What is it you don't like about the lithiums. they are excellent!!!
