Traction Loss only scn-5 with d-box

If SCN5 breaks, replace with SCN6 , or DC motor and JRK.

I'll get one of those tension weight pullers when it's all setup and pull it horizontally to see if the forces equate to 10kg.

The Castor's your after are 3" or larger and the Wider style wheel i feel is better suited for a larger load, So avoid the skinny soft wheels. You dont need any Crazy Chemical resistant wheel's but Dont cheap out on "roller blade" wheels like i tried the first time, lol They worked but added a tiny bit of friction due to "squishing" under load.



Maya is a Good guy for hooking up people with the Dbox, but imo he sells it a little hard on the tactile side, lol a Few of us have experienced a Dbox and some may like it some may not, same with the GS4, its not everybody's Ideal cup of tea. Thats the greatest part about DIY, you can Do what ever the Fuc* you want to lol. I look forward to seeing this complete to say the least. Lets hope the Actuator can hack it, but like we've said SN6 after then a DC/Winch after that, lol We'll get Something to work for ya.

All i know is if you throw X amount of weight to one side at X speed, and you expect it to re center/Complete opposite direction change as the car in game pitches side to side.....Its a Lot of F'ing stress on the connection points.

i looked to see the inertia calculation if I were to plug in some #'s but it felt too much like high school....no dice

Castor's are classed as Rigid Plate, just makes searching easier

Here's a YouTube link showing a Linear actuator being used for traction loss.....

Hi, very nice cockpit !!

For SCN5 or SCN6 question.

You should know that the SCN5 very quickly out of breath with high speed.
Seeing your cockpit, I would previlege type cylinder SCN6

After watching the YT video again, I have this observation to make. It appears that the people using the 3 DOF Sim are fighting with the wheel. Now the wheel and seat is attached to the "sway" feature but the wheel doesn't move in relation with the seat, thus you trying to "hang on." If I was to build this I would have the TV/Monitor/Screen closer and the seat and steering wheel mount move together.

I totally agree with you!
And that's what I'm doing on my own

A seat mover is for simulating you getting pushed back under power and forward under braking. Hence "fighting" the wheel. So its design represents more true to life results
In this video, in the bottom right hand corner, you get an idea of that


However, personal preference prevails of course.
Ive had full frame sims in the past.

Ok back on subject , @Ministrinity if you plan to just use one scn5 under the sim as a drift axis, just make sure pivot is nice and strong and the rear is supported well and running on bearings , you will see that it will take bugger all force to move the rig side to side, the real issue is the catching of the inertia as the rig stops, A one in two lever like the old frex designs would 1/2 the force being applied but the actuator but also have the amount of travel the actuator will have.
But really might not be needed at all if you have another idea of connecting the scn5 ?

"A one in two lever like the old frex designs would 1/2 the force being applied" can you show me an example? From what I can see in the YT video the actuator is attached to the side and center post.

Little question

Where did you find the springs hooked to the harness?

Thank you in advance

Traction loss "motor" will be attached to both "Frames" not the seat post itself.

Most hardware stores have a selection of general spring's. IMO go for something you will struggle to "pull open" by hand.

Stand corrected, sometimes I struggle for the right terminology

Ok, If you have links to online store I do not mind

Thank you for advance

Found these on EBay http://www.ebay.ca/sch/i.html?_odkw...+springs.TRS0&_nkw=extension+springs&_sacat=0

Also might want to look at bungee cords or rubber tie downs such as these, which should be fairly common as its used in holding tarps down on trucks, trailers etc. http://www.ebay.ca/itm/6pc-10-15-21...ler-/281593994210?hash=item41904f5be2&vxp=mtr

A big thank you !!!

bfst, I watched the video you suggested and paid particular attention to the action of the seat in relationship to the steering wheel. They don't change, its the driver thats doing all the moving and its the upper half of his body thats doing most of it. We must admit that to achieve this simulation in the "Racing Sims" we need the more aggressive action whether its the DIY or Commercial types. So does this system by GEKO better represent what actually goes on..... compare the movement of the driver in your video to the demonstrations at http://www.gekosystems.com/en/products/gs-105-motion-simulator/videos.html#GTREvo

Reviews of the Geko aren't exactly favorable if you read the right one's, Yes Some think its the greatest thing since sliced bread, but......ya.
