RE: Please help me get started
Or,
There has been some good Nelson .40 Q500 motors sold at that auction site lately. Nelson came out with a Long Stroke motor and some of the top guys are selling off their Short Stroke stuff. There is one listed on their now that would be a great fit for your Scat Cat.
Check this item # at the auction site: 300113449591
The person selling it is a racing friend of mine and a reputable guy.
Most of the Nelson Stuff has been selling for a little over $200, so you can find a good buy if you keep your eyes open.
