RE: weston magnum warranty information?
Just a devil's advocate question, isn't the warranty information on the box the plane aand or engine came in ?
Also did you rev the engine up on the ground several times before first flight ?
If I were you, as I have learn by visiting RCU , keep calling Weston USA and ask for somebody in a managerial position. Under no circumstances deal only with customer service personnel.
