Anyway, this is really a wonderfull job. I've also building a SU-27 cockpit, but I had troubles with the measures because I did not ha any blueprints. Your job is really weird!!! :thumbup:
Here are some photographies of mine, they're old and now my cockpit is close to be fully fonctionnal, powered by IOcards from opencockpit. We're also developping a direct interface between LUA and SIOC and it is also fully operationnal. Next step will be to pilot steppers via USB stepper interface from opencockpit, to motorize the needles of the instruments.
I'm also planning to build a cockpit vesion 2 with correct dimmensions...
I'll soon post more recent photographies...:)
