    at the moment all 4 servos are connected to Axis 6b.

    I needed more axis to define in Simtools

    I already use 5 Arduino uno in Simtool.

    1 Arduino for wind simulation and vibe with SimHub.

    Looks fantastic, thanks for sharing!

    Ive been pondering doing this for years but ive been unsure of the speed. Now that got a system that moves my whole rig around i can drop the direct flaps and go for this i think. How is it for racing? Is it fast enough?

    Ive actually bought 12x and plan to use 4-6 in the seat and perhaps do a Anti g suit style for flying with the rest. Its better to have them and be able to use it later

    Finally got part of my order of 10x as i was just looking at the numbers on the pad but turns out they are 9x16 so they are a bit small. First impressions are quite good though!

    Another thought is that you could probably fabricate these if you need specific sizes. Just a valve, pump glue and some tough inexpensive plastic. Then i would definitively go with a larger hose. 5mm and even less on the fittings means more torque needed and slower air flow. You could probably fit larger valves on these too though.

    I have made 4x square from the wrong ones ive bought and ill glue them together instead for a larger surface as i wait for the rest.

    Another thing is that flight and car is a bit different but since you can just move the pillows around you get get a better heave for flight and sway for racing.

    how does the air bad add to the experience ?

    These are just my initial impressions and i was expecting it so it wasn't a surprise. If there is equal hard pressure on both sacks and granted they are somewhat small you can feel small changes well and its not really a big issue. But the bigger bags you got the more of an issue it becomes going from 100 to 0 quickly

    The bag i made is about 29x14cm and airflow is severely restricted if i put my full weight on it and it takes a while to empty

    So small stuff, great! Bigger stuff and you need bigger tubing. I will modify mine with bigger valves for sure.

    Would i still recommend it, no doubt! Its so easy to modify and implement!

    I think ill be using it as a anti g suit to put pressure on top too. The big one works well over my belly.
