You probably already know this but: if you go the RC way, be kind to the
RC pilots and either stick to 27 mHz or avoid the aircraft-only
frequencies. Boats and cars don't get written off by a bit of
interference like aircraft do.

There usually are no RC equipment near where I fly, and if there were I
would have a problem too if they were on my frequency. I however am
only transmitting for about 1/2 second for each photo so it it not a
continuous broadcast.

Shortening the antennas, on the receiver and transmitter on the
sailplane units would also reduce interference risks for all users.



It would also be interesting to know of the IR control systems used for
indoor models work for this application or if they get swamped by
sunlight reflected off the wings and fuselage.


Tried that - some pictures work - but the sunlight is definitely a
problem for many [but not all] angles. I got some good shots using a
Canon Powershot G5 and it's IR remote, but a lot of shots failed
because of the sun. I had built a glareshield that helped, but in the
end that was too frustrating to everything lined up for an air to air
shot and have no photo.

Sorry to hear that!
