I am thinking about moving into gassers and have found a Mac 32 ready to bolt on for $65. The person selling states that the weight is 4 lbs & 5 oz and that it turns a 16/6 prop at 8850 rpm's. Is this a decent engine to get started with (I've been into nitro 40 size planes for awhile and am ready to ditch nitro for gas if I can find deals like this)? What would be a good size plane for this engine? A 120 size? A 25%? I would appreciate any information anyone can provide to me about this engine (I already ran a search for this engine and did not find much useful information so I'm asking in here) and recommendations surrounding this engine (planes, props, things to look for, etc). Thanks!!

Mike
