Hey everyone. Thanks for all the help i got with building my first DIY board, the Kushboard.
I’m back again with another build as my Leafboard, a $299 kickstarter priced board has broken down after 9 months of heavy use (daily). Yea, i tried. The support team didn’t help much either so i figured it’s time.
Installing the pulley, As i’m going for a 10S3p, the top speed will probably be around 40km/h or so. Hence i went with a 44T 15mm pulley. I have a 14T and 16T motor pulley so i will be playing around with the gearing ratios. Any gear experts able to advise on the difference between 14/16T? I know that 14 will have a lower top speed and 16 for a higher top speed. What will the torque performance be like?
I purchased the Jet Spud enclosure from @Eboosted, and after staring it for a long time it seems that the long enclosure will mean that there will not be enough room for a ‘traditional’ mount.
Great Men that you also went for the Spud. You are gonna love it. As short deck it’s almost perfect. The only improvement would have been a usable kicktail. Looking forward to see how it turns out!
Yea I’m really liking the look of the deck with the black Abecs. It’s like a monster truck! Imagine if I went with 107s. I didn’t because that’ll increase the top speed even more and I don’t want to go that fast.
I can speak from my experience. My hub drives goes 40kmh and I feel pretty stable on the spud, even with quite loose trucks for better carving. I agree that on a short board it’s already quite fast
So the other day i met up with @ervinelin because i wanted to get a remote from him. It’s a modified version of the mini remote and surprise surprise, he lives just 10 floors above me. Do check out his remote build thread if you’d like to DIY one!
We met up downstairs the carpark and got a chance to test his remote as well as his board.
Here comes the crazy part, i wanted to cut the wires from the battery shorter, and after cutting the red wire, no problem. But as i was cutting the black one halfway, i think the plier touched the red wire as well, and i guess the plier connected the two together and fireworks came out.
Enclosure arrived! Here i’m cutting and drilling the holes for the charging port, power switch and battery % indicator.
Barely able to fit. Maybe i shouldn’t have wired the batteries like that.
Unfortunately i wasn’t able to mount the motor in front as the mount was long and would hit the enclosure. I had to reverse mount it, no biggie.
Now the problem is that the mount is already angled as best as it can, but the motor is too low to the ground. A speed bump would eat it up. I’m going to get a longer mount and have it custom CNCed so it can be angled a lot more so it’s nearer to the deck.
Other than that, i assembled everything together and it’s done!, well once i get the custom motor arm that is. Here’s how the ‘almost’ final product is, the Kushboard Jr.
For now, i’ll ride it on flat ground only, i used the gradient calculator app and it could only go 15 degree before the mount touches the ground. Oh well.
Nice! @Eboosted 's enclosure is really low porfile, love it! He mounted the motor in front, but I think he used a custom one or TB motor mount. Other than that let we know how it rides! Spud rules
New mount came, it has a longer length and the adjustment holes were rotated so i could angle the mount higher. To work!
Much better.
I also printed a front riser out of TPU with 90% infill. Modified the model courtesy of @rey8801 to have a more rectangular nose.
Maybe it’s a bit too long
The previous battery arrangement took up too much space so i got it rewired and also a smaller BMS at the top. Looks a lot better now and not cramped.
Also changed the stock pivot cups to Riptide. Tbh i have not felt the difference from changing pivot cups. Bushings yes but pivot cups feel oddly similar despite changing em.
So yea, that’s about it for the Kushboard Jr, what’s left is to get the DIY remote from Ervine set up and call it done! Currently i’m using a mini remote but i can’t wait to use the DIY one.
Time for an upgrade, or design change. My Jet spud deck’s paint started to crack and chip, so i stripped the paint and painted a new coat with car paint.
Also switched to 107mm Reflys
Think i’ll do some rearrangement on the inside as well.
Metallic green!
switched to XT60 connectors so it’s not so cramped. I also got a Flipsky 4.12 so i can run FOC.
In preparation for @nuttyjeff’s gear drive, i had to cut the hangar to fit the mount and bearings precisely.
I also stripped and repainted the enclosure with a 2 component truck bed liner spray for more durability.
