RE: Manual Start Box AMT 280
Did you pop open the box to see what kind of battery it has?? I know the Data terminal has a 9v in it.
If you don't get a real answer... PM Jroth. He is a field rep for AMT, and will generally give you an answer faster than emailing US Microjet.
Last thing... if you decide to not use that engine, and want to sell it... Let me know. I wanted to buy it originally, but I didn't have the cash at the time.
