You may have come across a file called CHCOMM3A.zip in our 'Hot Files....' Section here , a couple of days ago, and perhaps even downloaded it. For those who didn't, I'll say this is a great file to have, among some others, if, at some point in your flightsimming experience, you intend to take it to the next level viz., adding motion by building a motion platform.
Whatever, and I mean whatever, you are EVER going to need further by way of info on the mechanicals, electricals, electronics and software are at this 'OneStopShop'website, "www.jimspage.co.nz", where Jim (Cairns) says you can get the whole motion part going for as little as US$ 200!!! That's incredible and proven too because I've been on the motion part of the job for some time now and am about 70% there. With my own variations to Jim's design since, I already had some stuff!! Everything's flexible.
And here's the best part? Incredibly, ALL THIS IS FREEWARE!! You don't even have to pay for FSUIPC if you are using CHCOMM3A in FS9, because Pete Dowson, when approached, kindly agreed and accredited the program for free use in FS9.
So make that little folder, call it what you will, and start stashing away all these free motion goodies, even if you're not planning to build now!! Never can tell when the motion bug will bite!! Maybe before FSX??
