The Kicker 2. The kickening continues.

Barely managed to finish it this year!
Happy holidays!





Custom deck - Roarockit street kit.



Laminated in 3 steps - 3 + 2 + 2 layers

3D concave on tail and nose:



Avenue suspension baseplates + 12" hangers from DKP evolve-style truck.

3D printed enclosure, with a hinge and swappable batteries.
TPU77D and 6061 1.5mm aluminium:



I was afraid enclosure will be too flexible, but it turned out super rigid.
Highly recommend hard TPUs like Kexcelled TPU77D or CC3D 72D, impact resistance is amazing and it’s easy to print.

Molicell p45b 12s2p X 2
My custom 5 inch pneumatics with 3d printed rims.
Hardened noname 6354 motors with cooling turbines.
FSESC 6.7, I wanted to go with Spintend 100v100A lite, but decided to use them for another project.


And my custom ELRS remote:

Dually front and rear, on a short board?:eyes:

Cool build, love the custom 3D prints

This has got to be one of the most unique boards I have ever seen.

Great job on the build! How does it ride?

I love this build, super awesome.

Do you mean dual tires? :smiley: Yea, these are rollerblade tires, singles are too narrow. I got a puncture once and didn’t even notice it.

I’ll post the enclosure designs on my thingiverse later when I fix a couple of issues.

I’ll try making a video tomorrow, didn’t have a chance to push it yet.

The deck feels great, shallower kicktail is more comfortable for my foot, normally short decks have 20-25 degree tails, this is 10 degree. Getting a slight issue with motor mounts hitting the deck because of that though. And previously I’ve used these wheels with 25mm risers, and now it has only 22mm. I might do a couple mm lift and grind some niches in the deck where the mounts hit.
Extended kicktail makes it super easy to manage the weight of the board.

And because of the bigger battery I can use way more amps compared to my previous board.

The deck feels great, probably best electric board feel I’ve ever experienced.
Didn’t mess with bushings settings, it just rips “out of the box”. Front - stock avenue bushings, back - 100a bushings from the DKP truck that I cut to match the avenue bushings height.

Motor mounts hitting the deck is not an issue when riding. I’ll keep riding at 22mm (+3mm TPU), don’t see the need for grinding motor niches.

No wheelbite so far. I’ve molded wheel wells into the deck, and additionally ground the well area deeper at the shaping step. Don’t want my board to look like it’s on stilts, like Onsra Challenger AT.

Forgot about the nose handle, it tries to rip your fingertips off if you try picking it by the nose.

The lower part of the enclosure is PETG, it cracked a bit on the edge cause it doesn’t conform to the concave close enough, and I didn’t account for deck flex (basically I cracked it deliberately while testing the flex jumping in the middle of the deck). Gonna reprint it with TPU 72D.

This thing looks like so much fun to ride.

How much does the kingpin deflect with that springy baseplate?

I’ve had a video on my previous board:

The front doesn’t deflect much side to side. Avenues suspension has very little travel as it is. But I think it still improves ride for shortboards or very rigid boards.

I suspect the back can flex quite a lot when you lift the front truck. I’ll probably make a video at some point, curious to see what it does.

This is such a cool build and I really like the riding videos.

Its really looks so fun to ride.

Can you do manuals at all? Or Will the motors drag,?

Can you do a long manual dragging the motors?

Also what does it weigh?

Do you mean clearance? There’s plenty of clearance to do manuals. The belts and pneumatics have a lot of resistance, but it’s possible with a bit of throttle.
I can do wheelies on this thing at lower speeds.

It can go this far before motors touch the ground:

The weight is 9.9kg.

600g heavier than my previous board. Hmm, the battery cells alone are 500g heavier. The enclosure is bigger, and the deck is slightly wider.

I could save around 100-200g by reprinting some of the parts with thinner walls and changing to titanium hardware.

Great clearance really and it’s not all that heavy.

I still haven’t managed to figure out how to manual using throttle… but you can do it. I have faith.

Do you have any little jumps or a kicker ramp to try to jump off of?

Also the fans are asking for more videos…

Very nice build! Does the FSESC 6.7 support 100hz ppm?

It uses 50Hz PWM

I think his elrs remote sends updates at 100hz

Ok, I’m gonna try filming my wheelie attempts and maybe try getting some air, once it gets dry again. I don’t have a ramp, I’ll look for speed bumps or some curbs.
The town look like this now:

I’ve looked at the code, it doesn’t look like it’s locked to 50HZ in any way.
It processes PWM input on hardware interrupts, as long as there’s more than 1ms between pulses:

But I could be wrong.
I’ve been running 100HZ PWM, it seems to work fine.

ELRS PWM is cofigurable, you can set 50/100/200…
It’s just how I set it up.

Noice, will try it soon. You have to update the can hz too because the default is 50hz .I think we need to capture some can packets
