This looks a whole lot better than one of those $30 mini cameras mounted to a beat up Flite Streak. Great video quality.

Here's the translated text of the description.
Installing the video camera in the controlline electric flight electromotion SKHOI60EP which is flight of the electromotive U [kon] machine, it tried flying. Just a little, becoming front center of gravity, the movement became sluggish, but flying normally, it increases. As specified it tried doing F2B performance. Category:

Awesome video... hats off to the pilot for even thinking of pointing the camera in that direction.
-
Very interesting!!
Also check out this video (a different plane and a different view -- same field).

I made a tongue-in-cheek post alluding to my personal feelings about electric flight and then watched the video and then removed my post. It may not have been understood to be tongue-in-cheek. But, I recall a simple post I put somewhere years ago about Mike Palko's first electric flying with his little red airplane up at a windy NATs, so I'll paraphrase that post.....
"No matter what is propelling that airplane, the pilot of that flight on the video is one heck of a flyer!"

I love it! Awesome videos.
Electric power is definitely 'viable' nowadays!! #^
Thanks for posting this.

I'd love to see the forward view with the camera mounted on the vertical stab looking out over the canopy and wings.

Dang! Every time I try and view a youtube video, my computer locks up.

Great video. Actually there are several posted by that person. The wingover
view is awesome. It was filmed somewhere in Japan. In urban areas many
of their baseball diamonds, soccer fields, parks, and flying fields are inside
the levees of the rivers that pass through the cities.

I'd love to see this with the camera in the cockpit (actual pilot's view).
It is very cool though.

I have seen these two before. This guy's motor run never seems to fall off due to use of the battery. Steady all the way through.
Bob, he is getting ground turbulence. Couple things that cause it. One is uneven color on his flying field. Part is green and part is brown. The temperatures over both is vastly different. Not to the average stunt guy walking around but to the air on the wing. He is constantly flying through different thickness of air. About 8' off the ground it wont be noticeable. If he were on a one color surface it would still happen but it would be more steady through the flight. If we were standing there and watching we would notice it worse in one area as opposed to another. Or maybe not. It might be the camera zooming in showing it off when it is really not noticeable. Also he is getting turbulence from the plane itself. Not wake turbulence so to speak but kind of like aero punch that a race car has. I am positive you have been standing near a circle and felt the blow by as a plane flys by. This is kind of the same thing. As he is flying along he is creating a plume of pressure above and below and around his plane. Like a big globe around his plane. Above his plane and it doesnt matter. Below his plane and it hits the ground. Now you would think the closer to the ground you get the worse it would be but this isn't so. I have been noticing this little phenomenon for many years and it is worst when you fly the distance of the wingspan off of the ground. I have tried to duplicate it many times at different altitudes but it only really shows at the wingspan distance. A little lower and no problem and little higher and no problem. When I say a little it could be less than a foot. Here is the tricky part. Our 60 sized stunt planes are about 58-63" wing spans and that is right where the rulebook calls for level flight. I have been flying many times and fly a much smoother solid pattern at 3' then I can at 5'. Flatter exits, smoother corners, better level flight both upright and inverted. It is the plane turbulence. If he flew that plane at 7' for an extended time or 10' I bet it would be rock steady. I have had many conversations with Bob G about this little phenomenon and it always happens right at the actual wingspan distance off of the ground. I remember one day in the heat of the summer complaining about level flight and the bottoms of the maneuvers. He asked me to fly a little higher pattern and see what I thought. Sure enough it was better. I noticed it right away the very first time I saw this video. Odd huh? That is what I think you are seeing.
What do you think?

"Ground Effect" is a layer of compressed air from the airplane to the ground that occurs at the elevation that approximates the wingspan. That's the way it is with real planes. There is added lift in this "compression", so I would imagine there is some chop there, too.
I wonder if the film was made at the Hachioji River bridge outside Tachikawa a few miles? If it is, it has sure changed since I was there.

I know girls from Hachioji.

HI Dale,
I, too, found the site to seem familiar. Doesn't feel like Japan, however. I can remember looking down into those "washes" and seeing a variety of apparent sporting venues and wondering if there wouldn't be some modeling going on somewhere. Hong Kong since the new airport opened might have had something like that between the airport and downtown but I was always so tired on the crew buses that as I try to remember now I can't seem to separate Honk Kong from Seoul or Osaka or Narita or Singapore or.....
Old timers sucks

The text with the video is in Japanese.

As a gesture of good will to Masuru-san and Kaz-san, I am going to go to great lengths to refrain from "practising" my Japanese language skills on them every time I see them. They have been quite gracious and polite as I basically insult their native tongue. However, my rendition of the Japanese favorite, "Sakura" (cherry blossom) just prior to their flights at the VSC seemed to put them at ease and they flew exceptionally well.
Howard is right, I hear Japanese on the video....I can't make out for sure some of the remarks, but I think they might be saying electric and internal combustion motors should have separate events, but I could be wrong....."denki cho-dai, desu ka?"
Ted, I can't reply to your "old timer's" comment, I wouldn't know anything about that.....!

You really mean that you can't remember anything about that!!! ;D

There's a very nice lady who lives here who reminds of things I need to remember. :) dg
