Batteries and tray for the S-800

[jrb]

You should be able to use just about any size with that battery tray. Looks like more than enough options for your velcro. As for powering your RX, you'll get that from your WooKong M flight controller at the correct voltage. No worries there.

Thanks for great help!
I haven't gotten my S-800 yet (Its in the mail to me in Norway) and I guess the tray could take some time to get, that's way I ordered the custom tray.
