i have read several positive reports on the Mecoa .46 that it is equal if not superior to the common .46 engines. For some reason the co. wont print the technical info on it. Anybody out there have the specs for it and your experience with the engine. Contacting a live person is nearly impossible, nor have they responded to my queries. Is that an indication of the product?

I'm thinking that it is because most, if not all, .46 sport engines are so close to one another performance wise there isn't any reason to throw specs around as they can be VERY misleading. As long as MECOA stands behind it with a warranty I wouldn't worry about it.

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

Yes, I have read most of it and agree that most .46 are similar, but some are more troublesome than others. I was trying to figure out the weight and compare to the "standard" 46 engine. Most manufacturers will list product performance and was wondering why Mecoa does not on the 46.

Any way, thank you for the information.
