For plow disks, you can find them at http://www.agrisupply.com/plain-disc...des/c/4500011/

The bigger the diameter, the less concave typically. We use the 14" ones and they work well. Sometimes they might flip a car over, but it usually "turtles" them. Only when hit at high speed will they launch cars, but again, hits at this speed with a board or curbs will either launch your car too or simply destroy it from impact.

The other thing that works well are "basketball spot markers". They are about 1/4" thick silicone circles. They are good to mark lanes, but don't provide much of a barrier.

Agreed. I hit a plow disc at the end of a straight and my F103 hit the wall at about head height. The wall was only 4 metres from the plow disc, and the car was about 40cm from the marshalls head

This has turned into a good discussion. Currently my club is using the Road Domes corner discs and they've been great but I'm getting pressure to use plow discs as that's what most of the bigger outdoor tracks use with their PVC tracks.
So what's the answer on corner pieces?? Seems nobody really likes what they use for the most part. After thinking about it, I'm wondering if a smaller corner dot isn't a better bet. Maybe 5-7 inches round, fairly flat and definitely having flush edges so theirs nothing for the car to catch or hop over.
Anybody think that sometimes we try to hard to make our tracks more like bumpers on a bowling lane ?? It's like we want our cars to bounce off everything we hit and keep going.

Thick, flat, flexible plastic can be made to create "flappers" that can be affixed to the end of straight pipe, or boards. These work extremely well, by giving a car that hits them a time penalty, without actually breaking anything, or launching the car.

At the Indoor Champs we use Teflon flappers, but they are generally very cost prohibitive. We got a serious deal on the Teflon we use, as it was in the scrap bin at our local plastic retailer......

Flappers are pretty common at the bigger indoor clubs in the UK, and the only track marking allowed at the bigger 1/12th scale meetings, due to the danger from flying cars with any sort of bot dot or plow disc - avoids dealing with insurance claims when someone gets hit at head height by a high flying 1/12th! With a flapper a car cutting the corner gets thrown off line so loses time, but doesn't get flipped or launched so doesn't get damaged.

Flappers are usually made using 4mm thick polypropylene or nylon strips bent around, as can be seen below. A large flat disc that cars can drive over can be placed under the flapper as they are easier to see. The disc marks the apex, with the flapper preventing the cars from cutting the corner over the disc.

There is no easy answer. Someone will always bitch. We just started using the road rail locally. I think they work great. Don't want your car flying across the track? Learn do drive around them not over them. Simple as that. Road Rail is much softer on my car than the PVC pipe we were using before.
