You just haven't looked in the right places or been around long enough yet! There are several good venders who can be reached on line, and many are found in the vendor section of this forum. Also, much of what you seek is in between the covers of Stunt News, the newsletter/magazine of PAMPA and comes with a membership. I have dealt with almost all of them directly or indirectly , and they are all pretty reputable guys. Some even set up and sell at contests. It is REALLY easy to not have enough money sometimes at a contest when these guys are there. I don't know what part of the country you are in, but make some effort to find out when and where contests are next year and hit as many as you can, even just to watch. Join PAMPA, and spend a little more time on the internet,and you will soon be overwhelmed with information. You'll just have to disseminate that info into what you like and will work for you. The only thing I haven't been able to find is MORE SPARE TIME TO BUILD AND FLY!
Welcome, good luck, have fun, and Merry Christmas!
