RE: aerohawk -swashball
I own an Aerohawk and from my observation, I don't see any easy way of doing it. The swashplates with the swivel balls in them are shaped just right to accept it.
On a separate subject, where do you find parts for your Aero? I could use a new rotor head since mind is starting to wear out somehow. It's a fun little heli and I'd hate to see it go to waste if I can't repair it.
