Thanks for your reply
I did a search on the internet for the Spectra part number and found some tech notes on the Tower hobby site which did not say anything about a BEC connection and I can not see any other connection on the ESC. So I guess I have to go shopping again. I saw a couple of ducted fans on ebay which look like they will work with this ESC they are brushed motors. I plan to use the motor to launch the glider and intermittantly during flight so I hope to extend the battery life. This is sort of my first experiment with electric power and so far it has been a learning experience.
Thanks again.
