My Cardinal RG was also a retractable. A mechanic during an annual inspection
found a clear spot just behind the right front seat. He cut a 5 inch dianeter
hole through the belly skin - and then took a standard 6 inch insrection plate
to cover the whole. He said it was not a 'streesed skin' in that area. He wrote
up a 337 form in the log and said it was legal. I would remove that seat, and
an opposing floor inspection plate. I built a sping loaded mount for the ELM -
even modified a hand held palmtop computor to act as an intervelometer to fire
the camera at preset intervals. The greatest problem was maintaining perfect
straight and level flight for verticles. Even with autopilot slight deviations
I would hardle notice would show problems in putting together strip sequences.
Good luck
