Prosimu T1000 5M 4DOF Motion System Review Part 2 “The Setup”

Here we have a motion system that is a complete custom package developed in house by Prosimu. It’s always interesting to me to see other peoples take on a motion system. From the design to the materials used in the platforms construction. The T1000 cockpit is a simple but effective design that just gets the job done. With a solid feel in the pedal tray and seat mount. The only flex I could find was in the wheelbase assembly. It’s easy to see that this is not the stiffest of mounts. And when I first saw it’s design, I suspected as much. Super stiff is not an easy thing to do with
a single arm construction with attachment points on only one side of the assembly. More strength could be had with a support structure applied on the opposite side. Of course you can just buy the motion platform by itself and mount whatever cockpit you want. Moving on to the motion platform section, we have a mostly robust heavy assembly. At first I was concerned about how thin
the metal is where the PRS200 actuators are secured. But I never noticed any problems during use while pushing the system very hard. Now this is a SimTools centric system. And while SimTools would never be called user friendly, Prosimu does give the new user the easiest path I have seen to date to get the system up and running. SimTools can be a daunting application to someone not familiar with it and some may not feel it is right for them. But if you take your time and test the settings and features that are explained in the 107 page manual. I think most will be able to master it. Now let’s talk about the motion that a system using actuators that move at 280mm per second and have a travel range of 150mm or 5.9 inches is capable of. At first use I was in my usual test
car the Ferrari 488GT3 in iRacing. Of course I was running it at Sebring. I had the main level percent slider at 100. The movement felt jerky even when rolling over the smooth pavement
sections of this circuit. A side effect of the PRS200’s speed capacities. However it was not difficult to find a smoother setting by setting the slider to 97. Of course all settings when using a motion platform are subjective depending on the users preferences. Once I had become more familiar with using SimTools to tweak all the available tuning options, I was able to find satisfactory settings
for any car that I tested. I also tested in Assetto Corsa and Project Cars 2. Where I was also able to get what I felt were good settings that gave me a proper sense of what the cars suspension was doing. Then it was time to start pushing this motion system in more demanding situations. First I went to the Rally cars in iRacing. Here is where some real fun can be had with Prosimu’s
system. Lauching the car off the jumps and then landing is something you have to do yourself to properly understand the impact of the range of motion the PRS200’s can deliver. The video
you see really does not do it justice you have to be in the seat. I was also able to dial in the traction loss movement to what I felt was pretty realistic for a car sliding on the dirt. So after spending a few hours with the Rallycross cars, it was time to push this system even harder. What better place to do this than with the iRacings Lucas Oil Dirt Racing Trucks. With multiple jumps one after another and sliding hair pin turns, this is the ultimate testing ground for a motion systems capabilities. Not only on how far you can push the travel elements of this system but also its durability. Launching off consecutive jumps, some larger that others, and then the hard off center landings can be pretty brutal. But also as much fun as I ever had in a motion system I think. Here again after pushing for a few hours, I did not detect any problems with the actuators or the motion platforms constructed parts. Even the motors temperature when touched, never got over the rooms ambient
temperature. While I cannot attest to the long term durability of the actuators under these conditions, I can say that they are solidly build units that can take whatever you dish out to them in the near term. I did experience some issues that I pretty sure where caused by the electric motors in this system. Not entirely surprising seeing that the motor cables used here are not shielded.
And the limited shielding the motor controller box has. I was able to limit it a bit with ferrite chokes attached to the all the cabling used during my testing. But extra grounding wires attached to the pedals and wheelbase would work much better. And of course proper shielding in the cabling would be the best solution. Now these are not the quietest actuators I have tested. With the SCN6
being the most notable with its typical SCN chirping. And the fans that the motor drivers units have in them also can be easily heard. But in my environment this is not an issue. But for others it may be something to consider. Now the complete system as tested here cost 9640.00 plus shipping. Or, you can by just the 150mm P5MP platform by itself and mount your own cockpit for 9364.00. Overall I had a blast testing this system. And it would be among the motion systems currently out there that deserve a hard look.
