So the other weekend I took the mountain board out on the beach here in Washington state (Long Beach if you happen to be local). The nice thing about this beach is that cars are allowed to drive on it, so nobody even notices if you’re racing up the beach on a skateboard (actually a lot of people noticed, but in a good way)
The downside to the mountainboard is the motors are not sealed, it’s chain drive and the wheels are 8" but way too skinny to be of much use in sand. It worked, but it took a lot of battery to keep going. Also, by the time I got done riding it was starting to sound funny, so we’ll see how much damage I did
Anyway, it was enough fun that I’m going to build a task specific board - a sand runner (caveat, wet sand). It will need to have large diameter wide but lightweight wheels, sealed gearboxes and some sort of covers for the motors. Basically the whole thing has to be sand-proofed.
This is currently in the planning stages, but I have started to assemble some parts.
I’ll be running 10S5P of 4k Ah 2170’s and, unfortunately due to budgetary constraints (and because you can’t get FOCBox Unity’s anymore) will be running some old VESC 4.12’s driving 6374’s that I have kicking around.
This is going to be physically a much longer board than your usual longboard - I’m thinking 4 1/2 feet long. The trucks are 16" wide so should piece together pretty nicely.
First up, building my own gearbox (since I can’t afford the eToxx). This thread will start with that and since this is my first build on this forum I’ll talk a little bit about the frame and batteries later.
