The thing about the Macstar engines is- My mate and I thought they were really good (getting back into the hobby) untill we went up against some half decent engines.
You could play around with the glo-plugs as well to get a good tune. But now you have the Axial i probably wouldnt bother.
What you may want to do is have a go at modding the Macstar engine for giggles. I have found it responds tomodding really well as my mate got into modding some of the cheaper engines we had lying around.


And if you stuff up the mod ? Its just a Macstar.


you would be surprised at how hard we got a Vertex engine going...lol
