Hi, not sure if I should be posting this question here or under the engine forums, but here goes...
Has anyone used ASP (Magnum / SC) engines for pattern flying? I have a 70-inch pattern model with an OS 140 RX on it but just cant get this engine to run properly, so I want to use a 4-stroke. Being on a bit of a budget, I cant go for YS or OS (and Ihave heard too many gripes about YS anyway). The ASP engines seem to be the same engines as Magnum and SC, both of which seem to get good reviews. I am thinking of the ASP180 four-stroke.
Thanks everyone.
