I built a Jet Spud commuter board last year in June, and was just recently upgraded to 107mm wheels and a gear drive. It was a 10s3p with a 190kv 6374 single drive. Total weight of the board is around 10 kilos, and range was quite a lot, for a commuter board.
This board is too heavy to carry around when i’m in a mall or in places where i have to carry it and walk. So hence, its time to build a lightweight Kushboard
The goal is to have a low powered board with a weight of maybe 4~6 kilos. I went with a 7s2p 30Q battery, so it’s pretty tiny.
For this build, i went with @nuttyjeff’s Avio gear drive, and it involves cutting the hangar for it to fit the gear drive.
Went to Jeff’s place to set it up
I put way more grease when i was home. Set up with 97mm Abec Reflys. This was the smallest wheel size to use with this gear drive.
Installed it to a 121c Orbiter Carbon fiber deck. Honestly i laughed a bit after installing both trucks because it looks so goofy haha
Here’s the insides, 7s2p 30Q battery, Flipsky 4.12 ESC, Lunacycle Antispark switch. Surprisingly with everything except the enclosure, it weighs right smack at 5 kilos. I figured it’ll be 6 kilos from the 97mm abecs.
I’m not a tall dude, so something like this is nice for me.
Tiny! Not as small as a Penny. It’s 25" in length.
Now comes a problem… The battery is a bit too wide for the deck, and i did not want to go for a double stack. There’s only about 10mm of space if the battery is in the middle, so the enclosure can’t have a flange coming at the sides.
Thinking of an enclosure design.
@nuttyjeff came through and helped me design an enclosure so that it fully utilizes the full width of the deck’s space. Here’s some CAD porn.
The enclosure will be sent in to be printed in Nylon. I was planning to have it printed in a cheaper filament and then mold it in fiberglass but just this time, i figured outsourcing it to get printed would be the better option.
One issue is that the side edges of the enclosure protrude out by about 2mm from the deck, so might have to heat form it a bit if its possible. If not i’ll have to bust out the fiberglass body filler again haha
If my back foot is near the end of the kicktail, the board will flex but very slightly. I’ll take a closer look at it when i collect it from Jeff this weekend.
The middle will flex up a bit if i stand really near the edge of the kicktail. The flex is really minimal, so i think the enclosure will stiffen it up a bit.
Nice. I love what @nuttyjeff did with the 121c Rover. Looking forward to seeing your finished Orbiter. I wish I had a 3D printer to make a sick little 121c build.
I put way more grease when i was home.
Set up with 97mm Abec Reflys. This was the smallest wheel size to use with this gear drive.
well done 
you do it well, it should be easy !
Is the deck flex ? a base / frame foam, seal, flexible could just fill and seal?
And of course i’ll spray truck bed liner over this enclosure
