Hi Joe : when I built my edge I glued in a carbon arrow shaft to stiffin up the fuse. where the motor goes I left enough arrow shaft exposed to slide the motor on the end after you trim the foam away to clear the motor and fasten with a small screw. Note : that on the gws deul motor, you want one motor on each side of your profile fuse. the arrow shaft is glued in along the thrust line in the fuse. look closely at my pic and you'll se what i 'm talking about. Hope this helps. If you need more help PM me with an E-mail add. and i'll send you more infoand pics.
