MAC Engines

[Cadillac]

I've heard a few good things about them. Anyone here run one?

Maybe try contacting Rich Reid at ReidRC for more detailed information. I'm sure he can either direct you to Andy Brown (the designer, I believe) or maybe some satisfied customers. It's worth a shot.

I've got the stock MAC. Running it in a Lightning Pro. Fantastic engine no problems runing against a K2 with a Rody C5. Would highly recommend this engine. Very smooth power band.
