Sinergy,
I fly [2] Giant Aeromasters on the Arf I use a 3.2 Sachs and the built one I fly a 4.2 Sachs. Both fly well. For really hot dogging it the 4.2 is the way to go. For sundays flying the 3.2 does the trick very well. Any good 50cc engine will fly it well. One I crashed
had a US 41 in it, flew ok but not to much verticle. I have had [3] of the Giant Aeromasters. Really my all time favorite plane, and I have 13 Giant planes, from 70" Yak to a 35% Extra 330L.
