hi john the keycams are good for wot they are.they are very light and you can put them on almost any size plane or heli.lipos in them last really well and take the micro sd cards.i find the high class cards give less frame drops.mine runs at 30 fps at 640x480 i think.they don't work very well on dark cloudy days.i have had all the flycams and the flycamone 3 is the best of them but are bigger than the flycam 2. lipo life is really good mine records for ever.the recordings are better than the keycams, unless its the flycamone 2 they are i think slightly better than keycams.i am going to post a vid on youtube today of my flycamone 3 so you can see the difference.i am selling it but one of the club members wants first refusal.
