@RunPlayBack pushed me to share my Vanguard build, so here it is!
I started this build 2 years ago and have learned a ton from it. This board is responsible for destroying many components (2 Flier ESCs, 2 VESCs, original APS mounts) but it is finally at a robust & reliable state.
Top speed = unknown
I start getting nervous at ~30 mph and back off, still has a bunch of torque & throttle remaining though.
I ride some rough pavement at times and fatigued the original stainless steel mounting bolts causing one to break in half. Fun fact, stainless steel fasteners are typically only half the strength of other non-stainless steel fasteners. Replaced the bolts with high-strength alloy steel and covered in silicone to prevent corrosion.
Enclosure is held on with a 2-part silicone. This allows for flex in the deck without placing stress on the enclosure.
dual high output VESCs from @chaka. These things are amazing and really bring the board to life. I have never once had a cut-out (knock on wood).
simple charging setup. Red wire has an anti-spark built in. I like to keep things simple so there are less failure points.
I use a velcro strap to store the remote
