The motor fitted to the truck. This can be moved to adjust tension on the belt. With no welding involved this leaves the trucks intact if I ever want to just use the longboard normally. It also in my opinion looks a lot neater.
A 14T pulley for the motor with an 8mm bore and 2 of M4 grub screws to secure it to the motor shaft. 36T pulley for the wheel unmodified measuring about 67mm. The center of this needs to be drilled to allow it to turn around the truck.
The back axle set-up. This new synconflex timing belt is reinforced with steel wires and should be much more durable.
So I connected it all up after soldering all the bullet connectors onto the motor wires and esc. I turned it all on, set up the receiver. We have power! It works.
Here the motor shaft is ground twice at 90 degrees. This corresponds to the M4 grub screws on the 14T pulley so will hopefully have a much better grip. This is the turnigy SK3 at 213kv. Lo kv motors need to be used for electric skateboards as they have more torque.
The assembly is then attached with bolts directly into the core and through the wheel. There are 6 holes for the bolts which are secured with nuts on the other side. This holds up well so far...
1.2 mm aluminium sheet was marked out to give enough room for the components. It was then cut out and bent into shape. Carbon fiber vinyl, steel mesh and brushed aluminium top finishes it off. Reluctantly the case was screwed to the deck.
