Hi Wayne!

About 4 1/2 years ago, I bought my first GMS Engine. I broke it in on an 11X5 APC and have since been running it with an 11X3 APC on a Something Extra. She had been turning that prop in the 15,500 RPM range, and continuing to get better. This year she broke the 16,200 RPM mark. Pretty impressive! It has hundreds of flights on it, and is still blowing the doors off of all the O.S. .46 FX's at the field. The AX, well, it is still too early to tell. But for the price, it is the biggest bang for the buck. As you can imagine, I have been trying to get people to jump on the GMS bandwagon for a long time. Every time I think I have someone sold on the GMS, they come out to the field with a new O.S.. Well, in brief, a friend finally got a GMS .47, and it does just what you guy's are talking about, dies at full throttle. I have taken a little ribbing over it, thus my interest in this thread. The guy has shelved the engine, and I am trying to get him to look at it to see if it has the offset hole. So,... I don't know if I am going to get the opportunity to play with it to help solve this mystery. I really want a crack at it!

For the record, I have the GMS .76 also, and it too is a beautiful engine. I bought a second one for a friend and ditto on that one. The power compares to many .91's and the idle is incredibly smooth and low. I have been running a 14X6 Zinger on it, on a Dragon Lady. It pulls that big plane through the biggest, prettiest loops you ever saw,... with authority. I am in the process of moving it to another plane, or I would tach it for you.

In short, I believe GMS is the biggest bang for the buck, and am anxious for this problem to be solved at the manufacturing level. Has anyone contacted MECOA about it?
