Just bought my first gas-powered plane from ebay (Had an electric as a teen)...it is a used durastick RTF with an OS .46 LA engine and airtronics radio installed. It's ready to fly once it arrives. I paid $250 for it (it was used for one year by seller). I'm concerned it may not be worth what I paid for it...not much I can do in hindsight, but just wanted to know if I paid too much and if a durastick will hold intrest?
