Tip on wheels.

If you want light, cheap, durable wheels. Go to yard sales and buy some toys. Alot of plastic toy cars have realy good wheels for RC. You can find them in in just about any size you want on one trip. My last trip to yard sales, I bought four toy cars. All for a total of $2.50. Got four main gear wheels and 12 tail wheels. They will fit most wheel hubs for RC.
