Steph,

Last year I helped the UT students with a UAV project so I'm sure you have limits and requirements. But electric less vibration and I know this from flying competition aerobatics and have been electric now for 3 years and having several companies behind me helps..<vbg>
Anyhow yes electric would be costly and not sure how long your mission has to be it might not be a option, glow would be the next best way
and is not very costly and no special equipment needed, you could throttle back to a idle for the photos. I will look later at the link for your project later this weekend.
Glad to see your planning ahead, the UT students gave me 3 weeks to help them and it just did not happen from on paper to flying..
that's another story..

Feel free to contact me direct at [email protected] if you like also.

I also have HERMES 450 flight time..37 foot wing at 420 kg..
