 We decided to use wood for the main frame supported by some aluminum elements. We started with a rectangular plate and cut out everything which did not fit into the mate crate. We decided to use wood for the main frame supported by some aluminum elements.

 Unlike the original concept of the Hoverboard we didn't want to balance the crate, as it would make controlling the vehicle much more complicated and was found unnecessary anyway. Unlike the original concept of the Hoverboard we didn't want to balance the crate, as it would make controlling the vehicle much more complicated and was found unnecessary anyway.
 The supporting wheels are castor wheels usually used for furniture transport. They have a diameter of 50mm and can carry a load of 80kg each. The supporting wheels are castor wheels usually used for furniture transport. They have a diameter of 50mm and can carry a load of 80kg each.

 The motor will be held onto the frame by the metal clamp in front of the picture, unfortunately this clamp has an inner diameter of 20mm whereas the motor axle is 16mm in diameter. To fill the 4mm radial gap we used aluminum tubing which was cut once to allow it to shrink. The tubing had an outer diameter of 20mm and a wall-thickness of 1mm. The motor will be held onto the frame by the metal clamp in front of the picture, unfortunately this clamp has an inner diameter of 20mm whereas the motor axle is 16mm in diameter.

 Unfortunately we did not take pictures of the step showing the marking and cutting out of the first slot for the left motor. So the next step is the mounting of one of the castor wheels. Unfortunately we did not take pictures of the step showing the marking and cutting out of the first slot for the left motor.

 After everything was put together provisional we burrowed a lead-acid battery pack from an e-pocket-bike to run preliminary driving tests. As you might have noticed in the picture, only one VESC is wired to the contraption, the other one is some generic ESC from Hobbyking. After everything was put together provisional we burrowed a lead-acid battery pack from an e-pocket-bike to run preliminary driving tests.

 We quickly taped everything in place, wired up one rc-receiver and off it goes. Happy with the basic concept working (more or less), we began adjusting the outer contour to fit perfectly into the mate crate. We quickly taped everything in place, wired up one rc-receiver and off it goes.

 To conceal most of electronics (including the motors) we decided to give the finally assembled crate 25mm clearance. This should be enough to drive around on mostly flat ground (inside buildings we had no problems except on stairs). To conceal most of electronics (including the motors) we decided to give the finally assembled crate 25mm clearance.

 To prevent dust from entering the crate we built wheelhouses. The wheelhouses have a height of 60mm, which allows to add a "lid" that is below the cutouts in the crate. To prevent dust from entering the crate we built wheelhouses.

 The harness for our daisy-chain is a row of XT-60 sockets mounted to the chassis ending in a XT-90 anti-spark plug. (The anti-spark plug has two contact points, the one you would reach first when plugging it in has an internal resistor to limit the current. This is helpful when connecting the battery pack to the VESCs as their capacitor-bays act like a short-circuit when empty, which would normally cause a large spark and contact corrosion. Once the plug is fully inserted, the second contact points provides the normal characteristics of the XT-90 plug.) The harness for our daisy-chain is a row of XT-60 sockets mounted to the chassis ending in a XT-90 anti-spark plug.
