Hi all,
My question is has anyone out there been playing with serious duration, as in a couple of hours? I need to run a camera ship for maybe 3-4 hours. General ideas so far are: 2.5metre (9') span, glider-like wing, twin booms with a brushless in front of each, folding props, inverted vee tail, camera in central nacelle, along with a pile of LiPo's, and maybe solar cells. I figure minimum (within reason) drag, and weight, props clear of camera in nose. I could use a single pusher, but figure you would still need two booms to clear the prop, so minimise drag and have two motors with smaller cross-section at the front of each boom. (Are two small tractors more efficient than one large pusher?) I figure the efficiency of solar cells aren't up to providing all the power, but would extend the range of the Lipo's. (Where I'm flying there is always tons of sunlight!) Any thoughts, or experience?
Cheers,
Russ
