hi,
what are the pros and cons for each one of the systems.
noise / complexity / maintenance / price / cleanliness. etc
is the 1280usb designed to control hydraulic valves ?
most of the diy systems i see are motor based. but the "professionals" are hydraulic.
thanks

The question is what do you want to do ? And if you begin to calculate the cost for each solution , you will find the answer by yourself ! with hydraulic how do want to do to control the smoothness for the movements , or the speed , acceleration ? And hydraulic if that seems easier to implement there are no diy simulators .That means that in fact that is not easy to build to be as competitive as professionnal. with motors you will achieve to build a simulator as good as professional and with hydraulics you have to have goods skills and you start from,scratch ! but anyway you can try ! With will anything is impossible ! ;-)

i saw some f1 teams using hydraulics. and wanted to know if other people build them too.
This is why i used Apostrophes. in lack of a better word !
are there any design considerations to make a 6dof platform more suitable for drifting ? (length of the arms for example)

For a 6dof more suitable for drifting , I think it's not a problem coming from arms or something else in the simulator design.You can find here many examples with dimensions to build your plateform. The question is : did the telemetry give as good information to make your setup to program the yaw effect. Usually there two effects yaw and/or yaw slip given from the telemetry. From my side the problem is more the sim setup to get the best driving feeling .I repeat with the dimensions plateform , arm etc you can find here you can build a simulator with enough yaw angle to simulate drifting.

the degree of yaw is determined by the displacement of the arm the displacement and angle is determined by: 1) maximum angle of the joint 2) length of the arm lever (not length of the arm) and of course bigger displacement need higher motor power to facilitate acceleration and deceleration of the big movement, you dont want big movement but low fidelity movement
My 2cent about hydraulics
thanos will know better, but i think the amc1280 can be connected to the controller of the hydraulics valves as long as it can be controlled via PWM or analog i never heard of diy motion simulator using hydraulics because the parts you need for hydraulics are expensive for fast frequency of movement back and forth it is sluggish the good thing about hydraulics is the ability to hold object at height without using power compare to motor that need power to maintain torque which is not useful for fast moving low weight payload
most of the "professional" use it for heavy payload motion simulator, like 6 seater, because the motor and heavy duty gear that can carry this will be more expensive

Hydraulics are more expensive and need maintenance more often than motor solutions. There is also possibility for leakages of oil due the high pressure that makes it unsuitable for home use.
Besides that if you can get of hold of one of the already build big rides, you can convert it for use with amc1280usb with just a few signal converters from 0-10v to 0-100mA current. It was done before for a Doron SRV 3DOF movie platform (15 seats capacity).

With will anything is impossible ! ;-) I had one idea of running a full time un-switched hydraulic system using one motor and pump and then 6 actuators using the powered steering principle, and drive the directional movements with much smaller servo motors connected to the steering shaft. I didn't get any further than coming up with the concept and then looking under my Toyota landcruiser to try and work out the available travel. i think it would be possible depending on the linear movement of the steering box. This could also be overcome by compensating with a servo motor speed multiplyer for a given angle.
