Here's my latest AP vehicle:

Irvine X-ite
Mega 16/15/4
7 x 4 prop
KAN 1050 NimH

Camera is mounted in custom made balsa and aluminium pod which is attached to the underneath of the plane using Velcro tape. No camera servos: shutter is held down by rubber band during flight.

Total weight is 900g (31oz)

Plane climbs very fast with the Mega and 7x4 prop. Can get it up to maximum altitude (too small to see) within a few seconds.

Another view.

And lastly.
