It's as I always say: bring out those pancars! Tell people about them, tell them about the low running cost compared to sedan racing, let them run one to get a feel, and in no time you will have a class again!
Most new racers don't know any other pancars than 1/12th scale, which requires more skill and budget to run competively than a 1/10th pan car. So let them know and feel what it is to slay nitro cars with an electric racer, and they'll be hooked, just as I was when I first drove one!
You really have some nice PRO10 pictures in your gallery.
Saw again the Composite Craft Lynx II which was one of my first PRO10 cars long time ago.
Regarding bodies I think the Protoform P35 still is used widely as could be seen from your pictures. Also saw a BBR Lotec which had tons of steering and downforce but I think this one isnīt available since long a time.
I have found some other bodies which I havenīt seen before.
Could you please have a look what brand/type they are?
