If you are interested in finding plans, mouthpiec, there are many sources. Flying Models plan service, Model Airplane News plan Service, The AMA Plan Service, Bill Northrup Plans, Bob Hollman plans, Ted Strader plans, Nick Ziroli plans, Wendell Hotstettler plans are just a few. There are also many other website only plan services. Some are downloadable for free, others will cost a few bucks. I would guess there are close to 4000 plan sets available, if not more, and not counting plans that are multiple sourced. These plans are available in RC, CL, FF, Static display, Antique, Nostalgia, up to date, scale, sport, aerobaqtic competition, and run from micro to super large scale. There are far more plans available than there are kits, ARFs, and RTFs combined.
