RE: Funtana Conversion Battery Question
Stephen,
No problem at all on the const pics.
As far as tools to create the ovals, it was just a drill bit (can't remember if it was a spade bit or a hole saw). Drilled 4 of them, then used an small exato saw to straighten the sides (and some sandpaper).
I used some standard sized Hitec 5475 digitals that I had laying around. These are used everywhere on the plane.
