To get younger drivers and more drivers you need a reasonably priced or cheap car. But, it has to be very durable. In my experience with junior/middle school kids, the only TC type car that meets those standards the 4Tec 2.0. We have run TT01E's and TC4's in the past.. We ran the 4Tec class like the Euro Truck Class except we didn't care what body they had and we ran Jaco Blues, which were donated, on grey carpet. The 4Tecs we bought came without a body. There were basically two issues with the car and that was an occasional dog bone would pop out and because of the design and tightness of the servo saver we had to replace a few servos. We bought cheap metal geared servos for about $12 from Value hobby and they held up well. If you want to get more people involved and have fun I suggest the 4tec 2.0. The people making decisions should consider such a class. In todays world the fact that the 4Tec is RTR is important. Two years ago we ran a Euro Truck Class and they did not hold up as well. Unlike many years ago the students had less help at home and there were problems with them building their cars. It could be called USGT Sportsman or whatever you like.
