New Engine System (Way better than slidars)

If there is not one video on YouTube of this, Then it is new my friends.
A wheel may have been around for thousands of years but it only came into use when one guy showed it to another guy.

Behold my friends the Sliderless Slider system
Invented by XXXmags and brought to you by me.

No more will you have cranks that shift around like crazy
No more will you be worried about spazzing or have to put on ropes to stop shifting

One constraint per piston, Two if you count the rope.

Don’t forget to like!

I just use ACF…

The point is to build and engine, Why don’t I just use propeller tool and thrusters on my planes while I am at it.

Very old method.
