Yasou William,
Grand idea. I've just this year returned to RC flying after nearly a decade away and I am amazed at what's available to modellers today. Some of it is easily affordable by the average modeller and some of it is not. There's GWS-type mass production and hence very low prices and then there's smaller productions like GTM (Glen Torrance Models) and much higher prices. GTM models are arguably the best of the bunch in most respects as regards quality and scale fidelity in the large flying model genre. It would certainly be to your advantage to do a comprehensive search of your competetion and see what they offer and at what cost.
I ususally scratch-build and not because I don't like kits but rather because I'm cheap. I can't see spending $200 or $300 or more on a model that can end up as matchsticks because of radio interference or someone unthinkingly turning on a transmitter on the same frequency or a mistake. That's just me. (Make any sense to anyone that I put a $1000 set of Michellins on the P-car?)
Try looking around on the
www.rcgroups.com site as well. The gas and electric scale forums are good places to gather info and opinions. What exactly are you proposing to produce? Fittings or kits?
Good luck,
Mike
