xxxgrumpxxx: My first 1/12th car was the CK. I raced it during the winter on our local indoor carpeted track, and it was an enjoyable experience for me. Although, I didn't expect to do well just starting out in 1/12th I surprised myself and actually won a couple of races, and had a lot of fun. I will be racing 1/12th again this year (after a 1.5 year layoff), and I bought another CK simply because I found the car easy to drive and maintain.
Concerning the servo, I went with the Airtronics 94145Z.
Have Fun!
