Scrub Psycho II mountainboard build

Post by vlaca2 » Jan 19 2015 12:00pm

Hi!

This is my secont build(first was an longboard). Planned to 2 motor, but only 1 implemented. Maybe i will update if necessary.

Components:

Board: Scrub Psycho II (8” wheel, 6,1kg weight, max 80kg load!!)
Motor: Turnigy SK3 6374 192kv
ESC: HK 150A Car
Battery: Turnigy 6s 3000mAh 20c
Control: HK GT2
Transmission: 6mm ISO04 chain, 10T/45T sprockets (from Conrad webshop)

Calculated max speed 35km/h. Not measured the real speed, but enought for me :)
Always push start, very light throttle manage, onroad usage, no cogs.
Lipo enclouser in progress :)

Awesome, well done! No welding? That appeals to me :)

Is it just clamped with the u-bolts? Is there anything to stop the whole thing twisting round?

Looks great! Awesome. I have no doubt that will hold indefinitely. The Ubolts and Ubracket will help with strengthening it.

Thanks!

I saw a broken welded scrub truck( maybe in french forum) so i chose this solution.

One motor, street usage, no jumps, its ok :)

Thanks for updating the pictures. Very inspiring build, I've been wanting to convert a board like this and I might have to take the plunge!

All we need now is some video of you in action :)

I have a similar mountain board that I picked up on the cheap.

Love the motor mount. I'm going to try to do that with mine.

Thanks for posting. Great ideas!

What's the weight on your board? Those brackets and mounts look hefty!!

Hefty? Maybe, not measured. But the motor 850g (x2 when i install second), i think no problem 2stk 6mm alu and L bracket :)

Hey mate

First off, awesome board! Just out of curiosity how far or long do you ride on a charge ? Are you still running on the one battery ?
