RE: Norvel's A6R AME .061 R/C vs similar sized engine
The Norvels are good running engines. I have had three of them and have had good luck with all three. However, if you don't mind spending the money, the VA .049 RC may be worth looking into. I am about to buy one and have heard nothing but good about it. They run about $70 from Kittingittogether.com.
