DTS_Maton Posted December 25, 2012 Posted December 25, 2012 has anyone ever attempted to build a real life 3 axis simulator for lock on / dcs http://www.parallax.com/Portals/0/Downloads/docs/prod/motors/900-00008-CRServo-v2.2.pdf if the flight sim could export a 3 axis/channel PWM signal to power 3 scaled up continuous rotational servo,s like the parallax type ? just brainstorming here!
JG14_Smil Posted December 25, 2012 Posted December 25, 2012 Hello, Welcome to the site. The motion simulators I've seen use stepper motors. I believe all the axis info you need to do this is exported. What were you thinking of driving with those servo's? I do wish I knew more about it. I can't believe that guy is not hurling his guts out on that motion simulator! :)
robert123456 Posted December 25, 2012 Posted December 25, 2012 If i would have the money i would look into modding the afterburner 2 arcade to make it functional with dcs. But who knows how much time and money and knowledge would that require. http://sega-memories.blogspot.com.ar/2010/04/introducing-kevin-kerinert-most-sega.html
DTS_Maton Posted December 26, 2012 Author Posted December 26, 2012 this got in the back of my mind since my vacation in new zealand i posted the servo,s as an idea to use the electronics of the servo the servo motor itself as the motor driver,s (serious mosfets) and power supply would of course need to be scaled up the difficult part would be some kind of position feedback to the flight sim as over time the position of the simulator in space ( 3 axis ) would get out of sync with the position of the plane in the game (virtual space 3 axis ) i posted the video as to see what kind of frame would be needed if the flight pc and servo power would be included in the simulator you would only have to transfer power over 3 simulator axis and servo power and control/feedback over 2 axis htis would also build in some safety as you could have a power switch inside the simulator to cut power should something go wrong
metalnwood Posted December 26, 2012 Posted December 26, 2012 I have thought many times over the years about building a motion platform, the only issue would be to make sure that it had heave as well as pitch and roll otherwise not much point for a flight platform imho. Technically it's not too hard to engineer but what makes it prohibitive for me is that I am no longer content with a small screen, small pit etc. My pit would weigh a heck of a lot now which makes the logistics of it a bit different, the design of it quite different to cater for the weight and then the costs go up as well... Too bad I can't seem to settle for a small pit thats light and would go on a much lighter/cheaper platform.
DTS_Maton Posted December 27, 2012 Author Posted December 27, 2012 wood maybe? after all the fastest propeller plane of the second world war was made of wood :)
metalnwood Posted December 27, 2012 Posted December 27, 2012 Yes, wood although wood is still heavy. When you add yourself, all the timber, all the screens all the controls you can be up to a few hundred kilos. Even at only two hundred kilos that still requires some expensive equipment to move it around at speeds that would be acceptable. I think in the end something like the GS-4 seat is the way to go for an in between. When you dont want to give up the big pit but you want to feel the g's http://www.ultraforcesim.com/Page_Home.htm
metalnwood Posted December 27, 2012 Posted December 27, 2012 This is more like the kind of design that is practical to take a bit of weight. Those geared motors are not cheap!

Cali Posted December 28, 2012 Posted December 28, 2012 Most people don't have the time or money to do something like that. I also don't have the space in my new house. Don't even know where I'm going to put my pit now. i7-4820k @ 3.7, Windows 7 64-bit, 16GB 1866mhz EVGA GTX 970 2GB, 256GB SSD, 500GB WD, TM Warthog, TM Cougar MFD's, Saitek Combat Pedals, TrackIR 5, G15 keyboard, 55" 4K LED
metalnwood Posted December 28, 2012 Posted December 28, 2012 (edited) I still dont like those designs, it seems to be a case of have your cake but not eat it because they are not designed to take much more than the person and basic controls. Also there is no heave just pitch, roll and yaw. I think there is a reason most sims are on a 3-6 degree platform. Having that amount of pitch would be awesome though, I could imagine it going to airshows with an oculus rift and the queues would be large. Edited December 28, 2012 by metalnwood
