Why Choose a Symdeck Motion Platform

Why you should choose a Symdeck motion platform.

Up until now motion simulators have fallen in to 3 main categories; seat movers, D-box style and hexapods. There are other devices which simulate sustained forces to the body which we also make but here’s why we think you should choose a Symdeck motion platform.

We could have copied what everyone else is doing and bought ‘off the shelf’ actuators and mounted them like the solutions described above but we had a vision of what we wanted to achieve. Firstly, it made more sense to us to orientate actuators in the direction they are simulating the force. Secondly, the setup had to be fully modular so users can purchase as much or as little as they require. Thirdly, they have completely flat tops without obstructions so can accommodate most other cockpits.

s1 platform

The s1 offers a surge force of up to +/-80mm @ 250mm/s. This is overlooked by most other simulator suppliers yet is found on £1M plus setups used by car manufacturers. Adding linear surge gives a great sensation with out the feeling of soft suspension you get with using pitch to simulate acceleration and braking. The gear shift ‘kick’ is an additional bonus. The mechanism is fully enclosed along with all the electronics so only a mains and USB cable is visible.

s2 platform

Our s2 motion platform houses 2 actuators with +/- 7 degrees pitch/roll @ 150mm/s unloaded with a capacity of 60kg per actuator at the front.  There is an articulated joint with a capacity of 150kg at the rear. The mechanism is fully enclosed along with all the electronics so only a mains and USB cables are visible. As you can see in the image below, the actuators are connected to the top by rods with articulated joints either end. This allows for a large amount of individual movement but the mechanism is completely unstable in this state. However, what is not shown is our proprietary stabiliser mechanism which allows motion/rotation in the desired directions but is rigid where you don’t want motion. This unique design allows for a lot of motion in a compact design.

There is virtually nothing better than taking ‘Eau Rouge’ with the one to one pitch available with this motion platform.

s3 platform

The s3 platform ups the pitch/roll to +/- 10 degrees and adds heave which can be up to 110mm @ 150mm/s unloaded with a capacity of 60kg per actuator. The mechanism is fully enclosed along with all the electronics so only a mains and USB cables are visible. This has four motors as shown below and again has our proprietary stabiliser mechanism to ensure the platform only moves how we want it to. With the heave you feel the bumps in the tracks as well as the jumps and compressions and along with the pitch and roll literally adds a new dimension to driving hilly circuits.

Whether you purchase one or all motion modules you’ll add something to your experience of sim racing. Using all of them together means you can really appreciate the surface details in circuits/ courses. Below is a picture of a customers static with our TL, s1 and s3 adding the motion.

Existing Solutions Explained

Seat Movers

Seat movers are the cheapest form of motion simulator designed to rotate the user forwards and backwards and side to side to simulate the motion forces of accelerating, braking and cornering. While this works to a point the main problem is the wheel and pedals remain stationary so they are moving relative to the user which can feel odd. Some add the foot plate as well so the whole of your body rotates. This limits the the user into using the cockpit built in and has limited adjustability and tends to be of a lower quality.

D-box style motion simulators

Pointing upwards and rigidly mounted, these types of motion simulator are well suited to simulate heave but tend not to be able to simulate much pitch and roll, especially with the shorter stroke versions. As the actuators tend to stick up above the base frame they need to be placed at the extremes of the rig which makes this even harder. If you see in the image below as the angle changes the legs have to physically separate but are not designed to do it. With either 2 or 4 actuators these designs tend to use pitch/roll to simulate surge and sway. Also, as they are not fixed at the bottom they can act like ‘pogo’ sticks and take off resulting in them crashing back down again. You are also limited by which cockpits you can use with them.

Hexapod motion simulators

Pointing upwards in a triangular formation these sims are advertised as offering full 6 degrees of freedom. However, to get good surge, sway and yaw/traction loss performance you need to purchase a more expensive version with faster actuators. This is because of the angle of the actuators, they are great at heave, pitch and roll but need to move twice as fast as to simulate surge, sway and yaw/traction loss as a simulator which has actuators pointing in the direction of travel. Again, you are also limited by which cockpits you can use with them.

Symdeck customer TL review

“Excellent fun and remarkably convincing, particularly when combined with VR. The seatbelts tightening under braking felt utterly realistic! Mike & Simon very enthusiastic, helpful and passionate about their new product too!”


“Saw it at Autosport 2019 and it was totally convincing. The technology is developed to a high standard by people with a passion for what they do. So impressed that I ordered one a few days later. Now itching to get it set up in the office.”


“Spent the day firing questions via email to Simon at SYMDECK concerning their TRACTION LOSS SYSTEM by the end of the day I put in the order , was promised within a week and yes was delivered on time, was very impressed with the packaging, a wooden crate which ensured it arrived undamaged.

SET UP…………..

Setting up was very straight forward, Once out the crate I just positioned my aluminium profile rig straight on top. Took the weight no problem, which includes a seat mover, DD wheel and my weight. Very sturdy product. Once Simtools was installed the process to set up TRACTION LOSS was very straight forward up and running within the hour.


Once dialed in ” Less is more ” Paddock hill bend at Brands Hatch came alive in fact the whole circuit did. Down into Rivazza at Imola under heavy braking the back end was squirming the motion from the TL was very impressive. The feeling you get when the car breaks traction is very good, you catch the slide very quickly . The extra level of immersion that the SYMDECK TL provides was worth every penny.”

One very happy customer!


“Best sim I’ve tried!” These were the words from 2 visitors who had a test drive today.

“When I looked at your website, it didn’t look as though the sim did a lot, just going backwards and forwards but now I’ve tried it I couldn’t be more wrong!

Moving backwards and forwards rather than tipping more realistically replicates the feeling of braking and accelerating. With the seatbelt tightening when you brake, fans blowing air at you when you accelerate and bass shakers giving the surface detail through the seat and pedals adds even more to the experience. And there all included in the price!

Don’t believe it? Come and try it for yourself.”


At the Autosport international trade show this year I got to try out one of SymDecks motion rigs with G-Seat that allows you to feel G load as you go around corners here is what I thought about it !
