RE: Mecoa .46 specs?

Suggest you read my response (post #62) to your initial inquiry posted in the thread "What is the best kept engine secret in RC?".
It is a reliable and reasonably robust .46SF clone in every way. It is not the power equal of contemporary .46's like the TT PRo 46, 46FX or AX. It is however sufficiently powerful to fly most .46 sports class models with ease, and an absolute bargain buy - in this country at least. In the US, you'd be silly not to buy a TT Pro instead unless you could get the Mecoa for considerably less.
The key to "will it have enough power for my model?" is in interpreting ARF manufacturer's suggested engine size ranges for their models. Most contemporary ARFs suggesting a . 46 are in reality suggesting it as a minimum powerplant suitable to the design IME. If they state ie: 46. to 52, that means it NEEDS a .52 if you want aerobatic performance in the vertical. The Megatech/Mecoa .46 is best suited to designs which state .40 - 46 required and have a suggested dry weight of < or = 2.5kg. Stick a 10x7 APC on it, add 10% nitro and it will sing. eg: 10x7 APC -> 13900 RPM
