Default Russian MAC 60 opinion

Hi people, anybody can give me al opinion about this low price engine?

http://www.hobbyclub.com/product_inf...roducts_id=291

Is it a high RPM engine? for a speed plane?

Thanks.

I watched the attached you tube video and read some of the info on it. It sounds good, I wonder what it would do on an actual speed plane platform, apparently the crankshaft has a big fuel passageway hence the higher RPM's, but that means the crank wall is thin so they recommend light wood props, they have had some cranks fail. But for that price its worth farting around with I think.

No such thing as a "MAC" engine, it is an MDS. MDS in Cyrillic looks like "MAC".

The best thing going for them is the price IMHO. Power is decent but nothing to get all worked up about, carbs have a reputation for being crappy, weak cranks. It is not a speed engine, it is a rear exhaust sport/pattern engine.

Here's an extensive thread: http://www.rcuniverse.com/forum/fb.asp?m=7044163

On page 5 he finally gets to the bench runs and comments on performance, then there is more later.

Good cheap fun I guess.
