Had a try myself some years ago,lashed an automatic wind on camera underneath a Pipster,at the front was a deflector shield to keep the oil off the lens,climbed quite high for the initial attempts and shot the canal system doing overlaps as they did in wartime,the results were very good considering that it was just a quick experiment,I made a balsa box for the camera fitting a cam on the servo which stroked the shutter.
A few years later I had a couple of requests to take some pictures for cash,one was a car boot fair,the owner needed some pics but did not want to go for the expense of hiring an helicopter,the field next to the said event was quite tight,I tucked myself in the corner and opened her up just clearing the wire fence at the end and then felt very uneasy flying over a lot of people albeit at altitude,oddly enough not many realised what was happening,I throttled back and took a string of pics,anyway he was delighted with them.
The next venture was for an amateur film company who wanted shots of a mini fixed with deer horns ( ?) on the bonnet,they provided me with a very expensive digital cine camera,made a frame for it on the side of the fuselage and after permission to use the local race course the Mini sped around the perimeter,I had to keep the model low and at the speed of the mini,it was the most difficult flying that I had ever done as just could not get the speed right,after about 8 takes we managed to get some film in the can,so if you see a fim called 'The Westener' the aerial footage is mine !
One model that I designed specially for aerial work was called the Overlander,a 100 inch camera ship with either forward or downward camera attachment,she has yet to be built but one day I will get around to it.
One answer is to have combined IC and electric power,shut down the IC in flight and fly on the electric with no vibration,plenty of room for experimentation here.
