You need to wedge out your trucks. That way you can have them tight but still turn sharp.

@lowGuido Can you suggest what angle to achieve? Im totally new to all of this truck adjusting thing… so some tips/suggestions are welcome 
Its a personal preference really. You are going to have to wedge them and try it and see. Then if its not enough add more wedge. You can buy them or you can make them from wood. But you will need longer hardware.
I’ve got emtb personally… so there’s actually a slight wedge already… and also a bit of an angle for the board in general (similar like, if you mounted trucks at the ends of regular skateboard)…
Though, it still seems not enough… I’ve got standard black bushings/urethane… and if I loosen the kingpin nut or rise the deck higher the board becomes too unstable 
I might try one day with wood… though Im not sure how close to that I am now lol… something made out of metal seems better… and if that swingarm idea would be feasible… I might as well contact a local welder, who would do something like that for me… without much cost… It just needs to be working… and for the idea itself I might consider doing it…
Making the wedge out of alumnium could also be an option (others have done it before anyways)… So I will definately keep this idea in my mind.

One idea on how the ‘‘swing arm’’ could be made:
At the end of the shaft/axle there should be a ‘‘moving’’ adapter…after that… there would be a rod connecting both of these plates… and then a ‘‘knob’’ or stick in the middle… for adjusting the direction

Dude had a kickstarter for his swing arm trucks. But you had to buy his complete board, he isn’t selling the trucks separate. And it looks like he’s had trouble delivering to his kickstarter backers.
I like the wheels…

Yep, I found the same board / guy a while ago… did not know about his kickstarter ‘‘backstage’’ but non the less - that is some awesome steering system… even the wheels looks really badass…
Too bad it probably costs quite a lot and there would also be trouble with mounting the motor… of course, unless someone would come up with a way on how to mount a hub motor onto these points where wheels attach to the arm mechanism.
To update the topic:
I tried to ‘‘switch out’’ the front wedge, I basically just turned it around (in opposite direction) and now instead of making the trucks more ‘‘straight/parallel to the road’’ they are now more ‘‘angled’’ and turn a lot better!
I can make ‘‘snappy’’ turns now… without any problems + I still got my stability since I did not switch out the rear end risers to the otherside…

I must confess that I had been riding with ‘‘too stable’’ wedge angle / position all the time!
I could post some pictures of the wedge angle I’ve got, if there is anyone who would be interested in seeing that!
[Edit]
Look what I found!
Someone has already done it before me, haha!
I bet his board turns way more ‘‘interesting’’ than our old / regular skate/spring trucks… Just not sure whenever this steering is firm enough… loose steering wouldnt be great either

I think that the standard truck design has stood the test of time because it works just fine without any fancy linkages or complications. You may need to tinker with the odd wedge here and there for specific setups, but if it aint broke don’t fix it.
It looks like ‘‘outback’’ / ‘‘frankenboards’’ also has such steering system.
I imagine they are quite turny… and in general, these 3 wheeled designs can achieve what is not possible easly for 4 wheel ones…
@lowGuido I agree with you that current trucks have been around a long time and they have already been refined pretty much not to search for something new and untested… but on the other hand, I think to achieve something new or what is not possible with them currently, someone indeed needs to come up (like it has already happened) with different steering systems…
They work quite okay as it is… and there are now more than one version of them - Other planet trucks, Roja’s, Gullwinger trucks… perhaps some more, I believe other planet does not use urethane but thought to mention it anyways.
So I assume there is a bit of choice anyways with what is currently available.
I can show you one more 3 wheeled board and it looks extreme what he can achieve with it… especially because he has made something like over 50 prototypes and his wheels tilt at an angle, too… but that’s for another time, since we focus more on 4 wheeled board anyways

Found this today:
I assume it is possible to find something new everyday…
Thanks for mentioning Flexboardz design…it can be maniable and stable at the same time
I wanted to post a pic of our new model but I don’t know how to do it…

@Flexboardz Bigger picture would be nice. I see that u have tried to ‘motorize’ the board in the picture… Any plans to do this for real in real life?
I think this might be a bit oh hurdle unless hubmotors are used for such ‘independant wheel’ designs. On the other hand - if u were able to come up with such steering system im sure u will be able to come up with how to attach a motor and belt there, if hub motors are not used… (or at least make direct drive with smaller wheel pulley and motor pulley)
This could be a big hit, if made and promoted correctly and wouldnt cost the same as Baja, since price factor is always important…
Your solution looks like would totally minimize the annoying shaking and bumping the whole board up when going over an obstacle with just one wheel or so.
Thanks Okami, I will try to find and post larger pictures of the Flex G2.
For the time being, we are concentrated on launching our electric scooters using the same wheel design (http://flexscoot.com/en/). If we are still alive after that, we will also produce boards for the mountainboard/powerkite market and the Eboards. Hubmotors are definitely an option but they are not yet available in the right dimension (as far as I know)…we are also looking for a closed sprocket reduction/transmission
Ideally, I would prefer to sell naked boards so customers can choose their own electric components (as they often know better than me about it) and keep the price low

You are right about the hubmotors… as of right now it seems it is hard to find one for 7-9inch tires. Unless it is custom made, of course.
Good to hear about your plans to launch them later on, after u have finished your scooters.
I assume someone will need to stay in touch / in-tune with you guys, to find out all the new info you put out.
Thanks for being on this forum @Flexboardz , non the less
Thanks for your welcome message…
I used to “read only” this forum to follow up the progresses about electric components (also hoping that , one day, someone will wonder about the board design ) as I was mainly concentrated on the scooters so I had no relevant news about boards…
Now, I will introduce myself to the forum members and I might open a post about boards design and stability if it interest the members
Btw, here are pictures of a E-Flexboardz made by a german rider few years ago (2011). It has a chain transmission but he made a real nice job to integrate it
