Meet the RAT

After some minor fiddling, I think I'm onto something here. A different perspective for Aerial platforms. This is a Mike Evans (power on RC Groups) design that's been modified. The idea comes from the Heptad and then I modified the airframe to have the camera point backwards instead of forwards. So what we now have is a Heptad that's been Reversed a Tad - aka the RAT. Currently the wing is being re-used from my Super Solution.

Re: Meet the RAT

The backwards facing camera is a good way to keep the prop-fuzzies from ruining your shot.
The only problem with backwards facing cameras is that any points of interest are seen up closer first, so by the time you zero in on whatever it is you are interested in, if is already faded into a spec on the horizon. The easy solution is to play the video backwards....It looks great!

Re: Meet the RAT

Awesome video! So nice and stable!

I'd like to have seen the cam at the front too, but this was cool too.

My videos are so shaky because the plane I fly it on (actually the only one I have) is just twice the weight of the cam itself. And I use those key chain cams which are only about 15g.

Re: Meet the RAT

Well guys, here's the thing. I already have a plane that points ahead all of the time. The Super Solution which can be seen @ . This plane is actually going to be used for stills so I'm not too concerned with the direction of the camera per se. I am more than a bit concerned with the direction of the wind relative to the subject matter. eg. a north facing subject & a north wind (common in my area) til now I would have to fly with the wind and the resulting ground speed has a distinct affect on the quality of the photo due to motion blur. Hence, the extra fuselage with the camera pointing back the way it came rather than the way it's going.

Re: Meet the RAT

Yes that is the big problem with the Power design, I talked to him about it and he basically does not fly past 8 to 10mph, his planes really cannot do a decent video above that. All that drag on the frame and especially all that side area comes to bite you in higher winds.
I fly Easy glider Pro with flaps, GoPro and powerpod, it does well, but runs out of video stability in higher winds also, gyro helps but I am not crazy about the gyro rock it produces in the video. No plane is perfect.
I personally never liked backward facing movies, but I am softening up a little, mixed together with forward facing stuff you could produce a nice multiview video
