HiI saw a video of yours, it is a PT from China. 250mm/s and 175kg per actuator! What´s the price? And how long will it last until it brakes?
You would be surprised, when most of us that built our SFX rig tried it at the low speed it would have been 100mm/s but once we were happy all was working as it should I don't know anyone that did not turn it up to it's full capability of 250mm and notice the difference in a good way. I doubt anyone would have left it at 100.Look at the YouTube Videos. 100mm/s is fine, otherwise it will break your bones! You can buy actuators with 1m/s, but that also will kill your wallet. And the price for a one solution paket is good! One actuator can handle 50kg, my rig with me as pilot is 135!
