I have an OS 40 LA on my Eagle 2. It provides plenty of power and balances perfectly without extra nose or tail weight. I think you would need tail weight with the TT Pro 46 or similar. No big deal really.
I use a O.S.40ts on my 16 year old Goldberg Eagle with a 11x6 nylon Prop. I only have a little Nose weight and she flys like a dream, I personally don't want anything more powerful than what I have. I have a wooden Master Airscrew 11x6 Prop that I put on the plane when I'm flying at a demonstration or show.
