This is a pack of about fifteen "Carb-O's" silicone throttle return bands from GMK Supply. These small silicone bands are super stretchy and work awesome as throttle return springs for all nitro engines from .12 to .32 in size. Double them up if you need more strength, or wrap them multiple times. These bands stretch!

Its strange to see bad reviews. I use these without any issues at all. The only reason I use a lot of them is because all of my friends steal them :-)
Be sure to use 2 at a time. Put one on each side of the carb. This will reduce the chance of your slide binding and grinding. Simply use a button head screw instead of the set screw to add another anchor point.
