I am a beginner and presently scratch building a Spitefull(Spitfire) and I would like to practice on my PC using FMS but I haven't purchased my radio as of yet. Is there a device that can be built inexpensively to simulate an RC radio to connect to my PC or perhaps an inexpensive device that can be purchased?

Now all of you are probably gonna say "a Spitfire for his first plane"? Actually I do have a FirebirdXL and I did start building the Spit prematurely(didn't research skill level for flying) Didn't realize this thing could be flying at 60 miles/h plus!

I do plan on building a trainer and learning on that but I would like to at least get the shell built on the Spit finished. I am really enjoying this experience scratch building and I am learning alot as I go from newsgroups as well as chat groups. Can someone recommend a place to download free plans for a trainer that I can scratch build?

Thanks, Chuck
