Yeah, at WDWAHO Raceway we have a "Foam Forest" to slow em down if all else fails. Since I have switches to power up the shutdown and we can drive each car back to the starting line the Foam Forest comes in handy when we forget and leave the switches in the wrong position! The forest is a 4" tall hunk of green foam from Jo Ann Fabrics cut to fit with the front in a curved shape so they bounce to the return lane side. We then took a dark green marker to it to make pine trees. Doesn't look too realistic, but does keep car damage to just about none.

Our track has a timed section of 16' with a shutdown area of 6'. Length was decided on by the amount of space we have and nothing else but that. If we had the space we'd of went with a 1/64 scale quarter mile 20'7.5". Our shutdown area rails gradually raise from the start to the end by .010". We also have a bath towel folded in half to catch faster cars . We have never damaged a car with this set up as long as you reset the towel once somebody has hit it. We did have a car running high 50 mph run past the towel and hit the 3" insulated wall with unfavorable results. That happen because the towel wasn't set up right. On our first track we tried running a separate power source to the shut down area with reverse polarity running on a adjustable 1 to 12 volts supply. We kept the volts low around 3 and also tried running a little higher. After running a series of test with and without the power source we decided to remove it because it wasn't helping the cars slow to much at all and we're sure it wasn't the best thing for the cars. Also if you make a pass and don't get your car right away, it'll sit there and hum or actually sit there and spin the tires in reverse because of the higher rails in the shutdown area which is not good for the motor brushes. We don't do that anymore since we built our new track. We did short between both rails which seems to help some. BTW Chuck did make a 76mph pass on Saturday night. Not fast to some of the Pro guys but the fastest we've ever seen a car go. That car will need a few towels ;D  |

Tim also uses loose towels at the finnish not exactly the 1 to 1 look but no damaged cars as well (foam bounces them back not pretty)

Loose towels are what I have used in the past. T jets on the whole are pretty stout little machines. Probably the most easily damaged parts now are the wheelie bars and the bodies themselves.
True Story: My then to be future brother in law, working on a tjet hop-up, was trying to reseat the top plate after increasing the brush tension a great deal. As you know it can be a finicky operation. Afrer many tries the brushes would not stay put. On yet another try, he aligned things perfectly, but when he snapped the top clamp in place,the brushes had hopped out of the mounts again. In frustration he THREW the t jet against the wall. It bounced straight back and nearly hit him in the face on its way past his head. He recovered the car, without a mark on it. The only thing he could see altered was....................you guessed it.......the brushes were perfectly seated.

I have the AW set also. I took two 15" straights, removed the rails and put a large mound of pillow stuffing at the end. The in-line cars get to the middle of the stuffing. The AW 4 gears barely get a couple of inches into it. I have 16 feet of powered track with an older AFX 22 vdc wall wort.
