I have been called worse but certainly willing to help if someone cares to pose a detailed question. I glanced through the thread but could not determine exactly what is needed. We have been focusing on increasing our production capacity and my main attention needs to be there.

Don’t worry, I guess it was mainly a joke from DavidF.
And I have no detailed question yet.
Glad to see boardriding business increasing production. Keep going!

Yeah I just wanted to let know @Flexboardz you are the one to contact when it comes to PU , just that…

After f****g around with rubber/PU for days, I’m finally testing the suspensions…

Amazing job, love how the project is progressing keep it up

Love to read the progress on this !
The deck looks super flexy, it looks like your legs are really bent inwards, which I bet is quite bad for your knee and not the greatest ride position
Perhaps building some platform that compensate for the inward angle ?

The deck tip angle is increased by the low point of view. The legs and knees positions are very natural (we will talk about stance later).
The vertical stroke is mainly due to the compression of the PU bushings (not the flex of the deck).

After decades of attempts, I’m still unable to glass a board correctly.
However, I’m quite happy with some progresses on the structural/fonctionnal/production problems.
Sadly, my obsession about chasing screws and other mechanical stuff isn’t improving! But there are not much left…

Glad to see this project still rolling! Could you give us a rundown of the progress that was made? I’m having trouble identifying all the changes from those pics.

You are right, I’ve been f****g around for so long that it deserves a map!
someday I need to come to knock on your door and to try one of those boards, I love this project

I will try to summarize the last years of development.
My objective was to adapt a Flexboardz design to electric power, taking advantage of the deck thickness to install electric components and using swing arms as motor mount.
I wanted also to add 2 fonctions useful for E-boards : adjustable Return To Center (RTC) to fit all kind of ride and adjustable height to accomodate various wheels size (from 6" to 9")
More difficult, it has to be produced, in very small quantity, with few suppliers, at reasonable price, with low tech (no cnc). (the Flexboardz ventures failed due to lack of producers).
Not to mention my obsession to eliminate mechanical stuff from boards…
First prototype was just a mockup, using existing aluminium parts to see the composite deck dimensions, volume, etc. (deck was to thin to receive a battery)
2nd prototype is a rare hand made board, done with a saw, a drill, aluminium plates, resin, carbonfiber and lot of sweat.
As it seems more or less fonctional, I ordered electric components and installed them.

At this time, I was using an internal gear transmission…as if my task was not complicated enough…
Somehow, I managed to connect everything and make it running.
I tried various model of aluminium cover too…
So I decided to order water cut aluminium parts to make a new proto, more accurate.
Example of deck height adjustment.
I tried also various models of aluminium case, tryiing to maximize space to install electric components with limited success.
I also wasted time on the internal gear, making covers. I will decid to stop this option soon as it was to complicated to get suitable inner gear.
I also made few aluminium cases.
I also changed the central part from cut/folded alu to composite as it’s simple to make myself.
Then, I made a new deck, with more space and a larger central part, with more space for PU bushing to get more “suspension effect”
Then, I made folded aluminium motor mount to accomodate “normal transmission”, gears, chain, belt…
As usual, I made also few aluminium cover…
but it was still quite tight…
Finally, I gave up the composite deck + aluminium cover design and made a closed composite deck with an electrical drawer that slides into the deck.
It’s simpler (much less screws), stronger, easier to “seal” and save a lot of space into the deck.
So, the picture below summarizes the results of the different steps, not the time spent, not the questions, not the failures.
Thanks if you have read such a long post.

Heh so many editions… nice work and effort…
But did u manage to get a desirable result?
Or u are still after the right combo of shapes and materials to use?
Really love the sharp turning angle and the option to adjust height as demonstrated in one of the pictures 
Hi Okami762.
Sorry guys, my post was a bit factual, depressive with a touch of bitterness (I drunk too much wine while writing it).
But YES, I’m pretty happy with the result : it’s simple (very few parts), light, robust.
I’ve integrated the 2 fonctions (rtc and adjustable height).
And the board can be produced without too much pain in the a**.
Even my obsession against mechanic was satisfied as the whole board is held together by only 6 screws…

6 very important screws.

Yes, eventhough they work like locking pins (nuts is only for safety).
But, to summarize my work, yes, I think that it’s an interessant way to build boards.

I was trying to talk about board structure, transversal design vs longitudinal design, and so on but I was probably too mysterious…
