Magnum Engines in RC Combat

I've been using Magnum engines in RC Combat since the 2002 season. I find that they are generally powerful and reliable engines, however, the carbs require some specific fixes to make the engines run reliably. Not surprisingly, the fixes are almost exactly the same for both the .15 size engines used in A class and SSC, and the .25 and .28 engines used in 2610 and B class. The carb designs are very similar. The carbs are actually designed fairly well, however they are not built as well as they could be. As a result, they will leak air, and shed parts in the air if nothing is done to prevent these problems.

Good luck!
