RE: Evolution .46 NT Engine
I put a new .46NT on a plane that previously flew with a TT Pro .46 and a .46 FX. The NT had a lot more power on the first tank of fuel using the same APC 11x6. Mine was not tuned perfectly, but that isn't a real problem. It was a little ragged going to full throttle, but smoothed out after a few flights. Easy to start and always has a lot of power.
My next plane will have another .46 NT. My Evo .45 trainer engine will go on something else later. That is a fantastic engine, also with a lot of power.
