I dont think youll have much luck here at the beginners forum. Try the AMA forum. It has alot of useful information. Did you try contacting the AMA? THey will give you all the prices and how much certain things cost so you can maintain your field. IF the field is in bad shape, write to the AMA about your situation, and theyll post your field up in their monthly magazine, "Model Aviation." There, people will see how much is needed , and they can donate money to your field. ITs all part of a slow process, but im sure with the right moves, taht field will be up in no time.
