Okay, I'm laying out a track design for karts. As a driver, what features would you like to see? Here's my list: 1) 24' wide (is 18' wide enough for karts? 20'?) 2) a decreasing radius turn 3) an increasing radius turn 4) an uphill turn 5) a downhill, off-camber turn 6) a high-speed turn 7) a challenging turn leading onto a long straight (*2) 8) a series of linked turns, where its unclear which turns to setup for and which turns to take "wrong" in order to setup for the others 9) a double turn (2 90-degree turns slightly separated that can be linked into a long 180-degree, though maybe not the fastest way through) 10) a 180-degree turn 11) a high-speed chicane Am I missing anything? Any recommendations on the minimum radius turn for karts? Should I worry about paving run-off areas? Maybe do the track 18' wide, but extend run off areas at track-out to allow you a bit of room to save a miss? P.S. Which karts? I might go with Rotax Max; but I am tempted to go with the lowest-maintenance and quietest option... electric... I've seen some electric karts with damned-fast specs.
