Ok on the wingmounted shots I used a JVC mini dv camera, I used 3 inch
wide tape installed from the trailing edge going up to the leading
edge, which made it pretty aerodynamicall, I didn't feel any big
performance looses or noted any different flying characteristics, but
then again those were schweizer aircraft which aren't exactly high
performance...
For the fuseshots we just taped a small digital camera to the
horizontal stabilizer...

Hope that helps...
