Am slowly building a 4" Fiberglass Dominator G2 from Madcow for my L2 launch. UROC has announced a St. Paddy Day launch, so I need to get it done! Have started looking at cameras but would like to have some input prior to purchase.
Question is a big vague. Camera to capture the flight from the ground? Or a camera to fly on the rocket? Assuming the latter, looking for a downward view, or out the side? What sort of price ballpark are you looking for?
There are a ton of options, from flying "real" (expensive) action-cams (GoPro & Sony have ones that'll do 720p/240fps or 1080p/120fps and perhaps 240 in the latest gen?), to the 808 camera which costs ~$5-40 depending on who you buy it from (and generally speaking you get what you pay for on those I've heard, don't buy the really cheap ones). 808 and Mobius cameras are the most popular ones I think, there are a few sizes of Mobius now, the original is 1080p/30, the newer ones are /60, and you can buy really nice mounts from members on this forum, either 3D-printed ones that attach purely to the outside or a unit that mostly mounts inside and just has a small 'cone' that the lens faces out. 'course some people just tape the camera to the side of their rocket. Heck, you can even just fly a cell phone camera if you have an old/cheap one sitting around.
I've flown the original Mobius a bunch of times, more recently I've come to like the Hawkeye Firefly Q6, bit cheaper than the Mobius and it does 1080p/60. Bit bigger than the original Mobius but I've been happy with it. Not aware of any commercial shrouds for the Q6, so I've only flown it electrical-taped to the airframe so far. Videos from each are in my signature link / youtube page.
Personally, something I'd like to try but I'm waiting for them to get down to a more reasonable size is to fly one of these 360° cameras, so that you could look up or down or out to the side. But I'll be waiting a while on that one I think.
