I'm planning to take my 6yr old son racing for the first time and since I only have one radio I need to get another one, I'm thinking about getting this flysky for now until I see he can handle it responsibly. I don't want to spend a lot right now until he proves it won't get broken and that he has a real interest in the hobby. Any opinions on this model?
