Shemp, the Magnum XL1.08A is an ABC engine. It runs strong and reliably. The only thing I can find fault with it is that because they put a huge carb on it for great top end power, throttle response is not very linear -easily fixed with throttle curve mixing on my Futab 9C.

The one I have belongs to the current or previous generation depending on how you look at it. The bolt spacing is 34mm. Just Engines is already selling the newer 1.08 under the ASP brand name, which has 42mm muffler bolt spacing. It seems that Magnum/ASP is standardizing on this bolt spacing for the .75-1.20 2stroke. The Magnum XLS series belong to this new generation.

Curiously, Magnum does not currently have a .75 2stroke. I bet when they do come out with one, it'll be identical to the ASP .75 I have.
