RE: anyone hear of a sig lil something extra?
The .074 puts out as much power as a 10, but the .15 flies it better than the .074, plus it's a cheaper motor to buy, the last time I checked the .074's are going for around 100 bucks, plus, the plugs are expensive, the cheap magnum .15 is like 60 bucks, and has 1.5x's the power.
