Question Vertical 90° arm okay?

Hi all!

i'm currently building a 2 DOF motion sim based on the compact sim from noor beast, and also Scruck's sim. But i have encountered a "small" problem.

My lever arms cant go down the much
Honestly i didn't even think about that when designing. Oops!

So i'm wondering if it's okay to use the arms in a vertical "0" position? so that would be 90°
i could also shorten them up some, but still wanna se if 90° would give problems

i tried to look for other build to see if they do it, but it doesn't seem to be a common thing

Looking forward to some advise!

Yeah i was wondering that. that makes sense. Thanks!

i think i will shorten the lever arm, should give me 50° instead of 20°

Do you use 360 or 180 hall sensor?

Unfortunately, you need to improve the design, the arms for proper operation must be horizontal as the starting position and +/- 45 degrees up or down.
I have another question, did you laser cut the motor mount ( marked with a red arrow ) ? do you have a file with a template ?

Second question did you cut the motor arms from ordinary steel or some special alloy ?

i used a 360 degree sensor

Yeah ur right, i messed up by making the motor mount to low, i sort of corrected it now. by cutting down the motor arm at an angle. Still not perfect but it seems to work.

No it wasn't cut on a plasma or laser, i have a small cnc mill at home. i used that to make it. i dont know how to share the file but i would love to, wasn't that easy to get right and if it can help someone i would love to share it.
It should work well with a laser cutter to, plasma im not sure because of the 8.5 mil hole

i used just ordinary mild steel, that being said it is 40x20 mil so quite beefy.

You can easily share the file by packing it into a .zip format and posting it as an attachment ( Upload File).

Regarding the creation of a simulator for driving and flying, there is one obstacle: for driving the TL is very useful as it simulates the loss of grip of the rear axle which is rather unnecessary in flying. Of course it is possible to combine these two pleasures at the expense of complicating the platform.

A nice project is here

Based on it I made my 2DOF for flying without a third motor for the TL.
The main obstacle in such projects is the necessity of welding for which not everyone has the space and skills .

Yeah i understand that, i want to re design it out of regular 4040 profile instead of welded steel. i had the steel laying around and it's cheaper so that's why i did it that way.

Here are the mount files for the MY1016Z motors.

Good luck with you're build!
