Don't worry, when you buy the engine from the hobby store ask for a prop to go with it. The cheap ones only cost around $10. As for field equipment I just bought mine too.

As for membership its pretty expensive because of the insurance and stuff. However in victoria i know that the insurance covers you for $20,000,000 dollars. My friend pays around $146 annual fee.
