I know the type but am not current on recent models. My last minicam was one that uses tape.

I suggest going to a store that has a decent selection and good prices (Walmart?) and checking them out.

I am soon going to be doing the same as you/. As said before am not fond of the Hero that everyone seems to be infatuated with (overly wide FOV and fisheye distortion) so will be interested in what you wind up with.

It is really hard to beat type of camera like GoPro or the other equivalents for size and weight and durability. Also vibration resistance. I used the Sony Webbie in the beginning and it was a great little camera, but it was not water proof and I actually like the fisheye view, I did not like the very limiting narrow field of view. Also, it did not like any motor vibration, lots of Jello effect. The small consumer cameras I checked out in stores have inferior picture quality, most limited to 30 fps and are surprisingly heavy for their size, with auto focus issues in our environment and light sensitivity issues. Also they have, for our purpose, useless zoom, which just adds weight, many will not take even one hard landing. I think they still make the Bloggie, with the rotating lens it was very aerodynamic. I now use mine, the Webbie, as a hat cam, great for that. Good luck in your search.

and so then the question becomes, what is different? Are the throws significantly different, or the aileron surface area as a percent of the wing area? You aren't going to get a fast roll with 3/16" deflection on the ailerons. I'm not sure the radian would roll well with 45 degree deflection either. The ailerons aren't very big

Have you tried a CF wing tube yet? It stops the wings from flapping and gives the ailerons some more authority. Also if your radio has enough mixes, you could have the flaps following the ailerons and that should do it.

Also some people have extended them out to the wing tips to increase the roll rate. Of course they would be more vulnerable to damage.

Yes, auto focus can really get annoying at times. For this type of application, I would like to be able to just set it to infinity and lock it there. I also want to use the camera for ground-based video and other things unrelated to RC, so the zoom will get used for sure.

Well, that depends on what you want to see in your images. The Hero's full-sensor FOV is about equal to a 12 mm lens on a 35 mm camera, which would be classified as ultra-wide or fisheye.. It is designed for closeup photography of personal action sports like snowboarding, which is the kind of activity featured in their promotional videos. For distant subjects as typically encountered in AP that means that ground detail is very small. To me the most annoying aspect is the curved horizon, especially when the view is tilting up and down making the horizon flap like a pair of bird wings. If that is what you want or can live with then all is good, but people shopping for AP cameras need to be aware of that.

Yes definitely all correct, It is in eye of a beholder, But we found huge issues with cameras not designed for rough service as I mentioned before that we could not live with. If the Webbie/Bloggie was water proof it was our favorite, many of the cheap handhelds were just overweight junk. But I have not checked lately, there are some new cameras surfaced in last 6 months. And GoPro 3 looks very cool. I like Gadgets!

You need at least a 7ch Rx and have all four wing servos in separate channels (plus elevator, rudder, and throttle). Then you need a computer radio that supports flaperons and dual servo ailerons and dual servo flaps. it's a pretty standard configuration for a sailplane

i have a dx8. ive tried to get it to wor as discussed but the flaps would not play ball. they would go down with an aileron but not up. then one would go both ways the other only down.
gave up.

Ok guys, to be fair to the crowd that does not like GoPro type cameras I remembered a guy in Quebec that did semi professional videos with a camcorder, Canon Vixia HF20, on Easy Glider Pro FPV quite successfully, He called himself Funjet2008 Here is a picture and video flying with camcorder on his glider for those interested. It is not Radian but easily could be. The conversion to pylon mounted motor is pretty standard for any fultime AV glider.

Careful, it is easy to delude yourself with that kind of logic.

At half throttle the ESC is hitting the motor with full-amplitude current pulses having a duty cycle of approximately 50%. The point is that you are not limiting the maximum current the motor sees, just how long it on. During the ON part of the cycle the current is the same as at WOT. It is still possible to toast it even though the average power might be within spec limits, which might explane why it is getting so hot.
