Thanks guys it is indeed 12mm, for some reason I thought it was some weird imperial thread lol

Any idea why spring trucks always seem to use a linear spring? I have a feeling that’s why I prefer urethane blocks to spring trucks. I like the more exponential shaped rebound I get perhaps.

I’ve seen egg shaped damps, why no non linear springs? Or have they been hiding :thinking:

Would make sense, if you also prefer egg blocks.

Today’s featured cowboy CAD . . . Its a “no moving parts” remote design:

The plan with this is to test out a couple ideas I have been thinking about:
1 - Can i print good flexure joints?
2 - Are these reliable enough to be used in esk8 remote design?
3 - What is the best layout for magnet and hall sensors. I have included 2 different options to see which is better (hopefully more linear).
4 - Can retrofit the hall sensor in place of the cheep pot joystick on a production remote’s electronics for low effort but reliable remote prototyping solution.

looks to me like one giant moving part :thinking: :man_shrugging:

Wonder how a squeezy remote would handle fall/impact.

hand strain from using it?

It should produce a rocking motion similar to an earlier size model i made previously.

The idea here being that its easier to switch between forward and backwards quickly and accurately.

I dont think it will cause any more strain than using a standard trigger remote so it should be fine.

With regards to falls and impacts im not sure. How robust is it? how much can it twist of axis? does this cause any control weirdness? will i need to add additional bearings to constrain it further? These are all things im trying to work out.

Got it on print now and if all is good im going to try and build it up tomorrow, maybe have it rideable by mid week.

oh I missed that early model, makes a lot more sense.

Seems much easier to use than a lot of remotes while wearing gloves.

So far it’s looking like a success. Just have to wire it up today and give it a test tonight :slight_smile:

Since I smashed up my bottom mount enclosure this week:

I decided its probably time to move to a top-mount style setup. That means i need a top mount battery as well as some sort of enclosure for my Unity.

Decided the ESC enclosure was the best place to start as its probably more difficult than the battery problem. I am planning for the cables to enter from below to keep the clean look. This was my first go at designing something:


After surveying material I have spare in my Garage and sleeping on it i realised that i could probably cut a lot of height out of the design so went back and took another stab at it.

Happy with it so far. Next step is to print one out and see if the size is about right.

Looks very sexy! Cant wait to see the final product. Guess you will make use of the workbee for this? :ok_hand:

Going to give it a try

Looks cool ! but I don’t really see the point, I personally never go backward so having an easier switch from forward to backward doesn’t seem that important to me

Decided to give this a go from some scrap plastic before cutting into a fresh piece of aluminium.

Looks about the right size. Some tool-path improvements to be made but i guess that is why we do these tests

Its not for going backwards, its for smoother and more predictable switching from throttle to breaks. If your racing this is a transition you need to make into and out of every corner.

new crazy idea im looking for feedback on.

I was going to try and narrow the middle section of a trampa deck but im concerned about the strength. Im wondering if bolting an aluminum plate onto the thin section will help me get some of the strength back or not.

Has anyone tried this? Or have any ideas what the limits are? @NoWind maybe?

I am pretty sure it would work. Ive got a trampa deck which was modified and slimmed down in width, when I bought it the guy had a trampa carying handle attached, the deck was stiffer than when I took the handle off.

Also trampa mentions their handle stiffens the deck slightly.

Go go go !
@Norules ride it some yrs like that :

if you bolt it it will help for sure, your deck gonna be more flexy and twisty.

Nice. Do you know what width that’s down to in the middle?
