This is part of the skill of flying: knowing where the edge of the envelope is, and getting as much of it as possible. If you ain't blown up a ship, you ain't flown. Trust me--I speak from experience ;-) ! Dana << Sam... perhaps a dumb question to the group. Why hasn't any of the many highly intelligent engineers in this sport developed load rated breakaway tow hook ? I quess the manufacturers of the planes would have to perform load failure crash test to determine the maximum tow load that their planes could take. Ideas anyone?? >> RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
