Strengths:
Build quility and price. Very comprehensive instructions supplied with thier motors. . .
Weaknesses:
not yet run mine long enough to uncover any weaknesses, that said though, the 'port timing' is a little too low for proper grunt. . . .
Overall:
Would certainly recommend these motors for a beginner all the way to a seasoned flyer. . . .

Strengths:
Large torque for frame size allows use of a larger, hence slower prop, hence quieter. Runs on 5% nitro. . .
Weaknesses:
I personally do not like the pinch bolt method of carb mounting which seems all too prevalent these days. Use of Castor recommended. . .
Overall:
I run this in a 64" Black horse Extra, which is designed for a 60 sized engine. Because it is a 60 size frame it drops straight in, but allows me to use a larger prop. Because it is then running more slowly it is quieter. The excess power also means that the carb setting is not hyper critical, I can back it off peak quite significantly, and never need to adjust it at the field.
