I think the 46AX is more than enough to get you started, but the problem I had with it was too much torque roll. So I switched to the 55AX with a 13x4 Zoar prop. Now I have better pull out power, quicker spool up and less torque roll. So if you can afford the 55AX go for it, but if not, 46 will be good. Also I never tried a 12x4 Xoar on the 46AX, it might be a good combo.
