I took the heat sinks off the controllers and replaced them with some U channel.  That let me mount them to the side rails and tilt them via a screw I threaded into the channel.

This will let me to adjust the ride angle as I can now change where the hoverboard controllers thinks level is.

This also lets me fine-tune both sides so they are providing the same RPM to the now physically coupled hubs.  I'm just going to go for greatest RPM, while close to the same angle.

This is an extreme example.  I'll probably tilt the controller boards about 5 degrees to start.

My top front decking is going to be rather springy given it is basically a 3/16" suspension bridge of two layers of acrylic/poly carbonate.  I need the area metal free to detect the rider via cap-sense, but I could just as easily fall back to a micro-switch.  I wanna try cap-sense.

Taking advantage of the flexibility of the deck, I mounted the headlight on rubber.

Pressure on the front deck will now aim the headlight up.

I think this will translate to the headlight giving you a look further down the trail when you are going fast.  Or it just may stay 'level'.  Either way, still cooler than a static mount.
