The requirement is to build a realistic two-seat ASK21 ..to train instructors? 2 seats makes good sense then. To train student pilots, you only need the students part of the cockpit, the instructor can do the instruction over the net like we did on the net fly-ins. In the same room, use a screen for every view you|the club etc wanna see, you're only limited by the hardware you have handy. ;o) > cockpit with linked flight controls at their correct location and > working instrument panels. ...with tangible switches etc that you touch even in the dark. No conflict there, fpv/vr goggles will yield even more realistic views than your 8 screen cage, once you track your hands etc. > With the FPV goggles I assume that you > won't be able to see what your hands are doing, and I'm certain that > the instructor in the back won't be able to see what the student in > the front is doing either. These two problems make a head-mount > display unsuitable for the club ..you of course will need to track (and show or simulate) _anything_ you wanna show on your screen(s), e.g. using web cameras to track hands and feet, using e.g. gstreamer to overlay webcam video on FG video, or model, track and/or simulate said hands and feet and show everything in FG. > but I might get one for myself at > some point as it sounds pretty good for home use. ..the sooner the better, will help you make a better simulator. :o) ..but do try before you buy, e.g. my HPHD in a wonderful idea, 72 degree FOV and a nice big 1280x800 screen, totally destroyed by requiring me to squint at the screen at 22cm. Use ~4.5+ reading glasses to focus at the horizon if you have perfect vision. > Cheers, > Vik > > On 19 May 2016 at 21:16, Arnt Karlsen <a...@iaksess.no> wrote: > > > On Tue, 12 Apr 2016 12:08:38 +0100, Viktor wrote in message > > <CANx-tGj71MVJqa9+cDP4U_PBtVtjGM=ffbz6wrhvhoju5bm...@mail.gmail.com>: > > > > > Hi all, > > > > > > I'm planning to build a glider simulator for my gliding club, to > > > be used for instruction.
