hey guys I was surfing the internet and i found some engine rpm figures.
i was just comparing the MOKI 135 with the 3M Mintor 140 and i found some interesting results;
the 3M Mintor 140 with tuned pipe and 15 percent nitro fuel turns an APC 16*12
at 8350 rpm.It costs with pipe $518

The Moki 135 on straight fuel with a standard silencer turns an APC 16*12 at 8300 rpm.
It costs with silencer $300.

We can see from these results that the Moki is a lot more powerful because it is only 50 rpm slower when on straight fuel without a pipe , unlike the mintor)
As you can also see the Moki 135 is also a hell of a lot cheaper(by $218!). One guy in my club has a Moki 135 and it seems to throttle brilliantly( as good as a YS engine).

On looks alone the 3M Mintor wins but if you are concealing the engine inside a cowl then it doesn't count for much.

It is clear that the MOKI 135 is cheaper,and more powerful, therefore better!
