This build originally started out using the 5" Skike wheels from Alien drive. Didn't work out. All the wheels I received were not true. The board would wobble like crazy. At first I thought the wheel was not centered on the wheel but that was not the case. I placed the bare wheel on the trucks, spun the wheel and one can clearly see the wheel was not true. I really wanted a board that ran on pneumatic tires. So back to using Abec11 flywheels. Parts for this build using Torqueboard 12s esc, HV switch, motor mount and pulleys, Caliber trucks, Abec 11 97mm flywheels, sk6374 192kv, 4s 10000mah Multistar, 36 to18 ratio, 15mm belt.
