Any of you using the Mecoa or GMS engines? Are they any good?
Looking for new engine that will run, .25-.30 size.
Thanks

Not me personally, but another combat pilot in the club has one.

His comments are that the motor is heavier than average, and only puts out average power.

Try the Magnum .28 or MDS .28 both are very user friendly engines with a lot of power and a reasonable price tag.

If you want the fastest (and lightest) engine and don't mind fooling with it, get a Norvel. Very light and extreemely fast but they require a little patience to get used to them.

Irvine is also a very good engine. Some of the "Top Dogs" are running them.

The most expensive (and some say the best) is the O.S. .25 FX. They are a very strong engine.

Havn't tried the GMS .25. I have a .47 and it is a powerhouse but a little on the heavy side. Theyare available at a reasonable price.

The GMS.25 is a good running engine, but not quite as powerfull as some of the others. It also is a couple oz. heavier.

The Norvel and Mag.28 are the pic of the litter in the low price range.

os.25FP and Irvine.25 are the best regardless of price.

Thanks for your opinions, I have a magnum.25 and a os .25 fx, but really didn't want to run the os, and the magnum .25 has a broken con rod. I also did own a mvvs .26 but never could get it to run right. I have been thinking on the MDS but don't know how reliable they are.
Thanks

The Magnum.25 is not comparable to the .28. Their just different cats of the same litter.

That's true. The Magnum .28 is a whole lot more powerful. It'll turn a 9x5 prop at the same RPMs as a .25 will turn a 9x4. This equates to 25% more speed, in theory anyway.
