ICEMAN - You can always mount a battery aft of the servo tray - I create a small platform back there and and tie-wrap the battery down. Also, you may want to re-epoxy the wing servo trays - they have a tendency to slip out mid-flight on the Rev 70. Good luck with your build.

btw - the way I post pics is to hit "reply" to the last post - then you have an "attachments" option.
