Unfortunately it did not survive. I think the battery being in there must have caused something to short inside even though it wasn't on. So all the electronics were a loss.
Anyway, I took this opportunity to order a camera I've been wanting for awhile: the Sony RX0. It has the form factor and weight of an action camera (only 110 grams), but it has a 1" sensor and very sharp lens. From samples I've seen online, the image quality looks amazing. As a side benefit, it's also shockproof and waterproof, which would have come in handy the last time out...
Instead of an R/C rig, this time I'm going to make one that rotates and takes pictures on its own using a servo controller. That will allow me to just focus on flying and save a little bit of weight to boot. Maybe I'll do another R/C one at some point in the future, but for now I think I'll stick with this. I'm estimating the entire rig will be under 300 grams.
I also ordered some material to make the new kite, a Rokkaku with vents in the sail at the lower spreader. Some tests with a cheap dowel and plastic version suggest it should be really stable and have a better wind range than the Barn Door kite, with much less tendency to get pulled down. Here's a video of the first test flight of the cheap prototype, which was in wind that's pretty strong for a kite with this kind of construction. The prototype is 5 feet tall. The final one will be 7 feet tall and use the carbon fiber tubes from the Barn Door kite and a high-quality sail material.
