Electronic Motorized Longboard - 11th grade

During 11th grade, my brother exposed me to a YouTube Vlogger Casey Neistat. Casey Neistat can often be seen driving around town on his "Boosted Board." My friend, Hunter, told me he didn't think it would be hard to build one of these of our own. For the next few months we designed models, prototyped designs, and researched models to base our build off of. Unfortunately, there is not much documentation to build one of these by hand without using an overprice "DIY kit." So this meant we needed to triple check all of our numbers prior to ordering the $80 high-torque RC airplane motor, $200 lithium-polymer batteries, $50 board, and $50 electronic speed controller.

Four months passed and summer came and we had a working electrical longboard. My board was flawed because the wheels couldn't handle the torque of the motor and instead the screws ripped a circular hole through the rubber injected wheels. Luckily we had only bought one set of parts, so my friend just took the parts for himself. My friends board is running flawlessly and though I didn't contribute to the mechanical design of it, I did help with the electrical setup of it.
