Another approach may yield larger lifting capacities, but it would require
considerably more time/skill to make work. Here's my thoughts on it:
get/make the largest flying wing you can:
here is one possible candidate from:
83" Span EPP/EPS Large Combat Flying Wing
Area: 1440 sq.in. / 4 lb.
EPS/EPP Full Kit: $90.00 / Econo Kit: $84.00
All EPP Full Kit: $130.00 / Econo Kit: $124.00
and mount a reverse rotation "pusher" engine to it. This will add a pound
or so. You might want to consider an electric so you arent vibrating as
much when taking pics, but this may degrade your lifting ability
considerably. If this is for very short flights then you can use a lighter
battery however and regain some capacity.
Install the camera pointing up. You'll have to fly inverted to take pics
but it will be protected on landings.
Launch it with a bungee catapult or somesuch.
Whatever the design, experiment (test fly) with non-expensive weight (a
camera sized cardboard box filled with rocks?) in small increments till you
get to the desired weight and are confident that you can fly with the weight
of the camera equipment.
It should have a lot more lifting capacity than a traditional plane design
because it doesn't have to carry landing gear or even a fuselage, which
means considerably less weight and drag. The flying wing design also only
needs 3 channels so the fourth channel, if you have one, can control the
Good luck, report back.
