It's really a shame you have chosen this engine for a trainer. This not a trainer engine, but a performance engine that requires some skill in set up. One thing you can do is replace it with a more suitable engine (Magnum 46 XLS, for example) and come back to this engine for a future project that can benefit from the additional power at a time when you are more comfortable with running engines. You haven't said what prop, fuel, glow plug you are using or if the engine is new or fully broken in. You can start trouble shooting glow plug, fuel, etc now, but I can sense your frustration with it. You want to be flying, not fussing!
