I flew one in the 80's. Absolutely wonderful airplane. I built mine with 52" swept top and 48" straight bottom wing and would do the same if I were to build it today. I agree with R8893, mine flew on the old K&B 61 with a 12X6 prop, and it would do most anything (flying, not the H-word). There are 46's today that put out about the same power as that old .61. I'm sure you will enjoy your Aeromaster.
