The GMS 1.20 and the Evolution NX 1.00 are almost legendary as being the two most-impossible glow engines to get running reliably. Most folks who've had either of these engines won't have much nice to say about them.

I myself have had a very good experience with the GMS .47. I bought a non-remote needle valve model that ran quire well. I have found that remote needle valves and cheap engines aren't usually a good combination. My Magnum .52 XLS 2-stroke ran much more reliably when I abandoned the remote needle valve assembly on it.

If you're looking for a cheap engine that is actually good quality and will provide reliable service, you have plenty of good options:

> Super Tigre engines are powerful, reliable, and very well made. Parts availability can be spotty, and Great Planes may not be distributing them much longer
> Magnum/ASP engines are good performers and good values. Mine haven't always aged well, but I don't have any complaints for the price paid
> JBA and SK engines from KangkeUSA. If there is a true bargain still available in glow engines, this is it. Very high quality at very inexpensive prices

Hopefully the quest for a good, inexpensive glow engine will never fall too far from the front page of the Beginner's forum here at RCU.
