Video of flight

I have hovered etc with the Helicommand equipped Blade 400, here is a video of the first out of hover flight I have made, including landing on an object (hot tub...covered). I fly it up to rooftop level.

I was kind of chicken, I didn't know how long the battery would last, so I minimized my time up there...also I still have some adjusting to do on the collective/throttle settings, I have too much throttle in to get it to climb. (so I use the battery faster)

But I am happy with the results...

The video was recorded with my camcorder connected to the 2.4Ghz video receiver. (it is located in the corner of the house the helicopter is facing). The Blade 400 uses the Spektrum DX6i RC transmitter which ALSO uses the 2.4Ghz frequency. I set the video transmitter to the lower end, and the Spektrum decides where to best put its transmissions (they go from about 2.35 to 2.45 Ghz).

Notice I only get one slight drop out and some video artifacts. The oscillations are from the Helicommand over correcting for my inputs.

Yes that is a camera

Yes under the middle part of the body there is a wireless video camera.

I plug the receiver to my camcorder and record video. (that is why I need the stabilizing system)

It operates on 2.4 Ghz and is very low powered...the RC transmitter/receiver is ALSO 2.4 Ghz. So I put the camera at its lowest frequency (within the 2.4 spectrum) and the RC system gets out of the way. If the RC transmitter is between the video transmitter and receiver, then I get some noise or drop outs.

I don't have any demo's yet...I only recently installed it on this helicopter (I originally had it on another smaller helicopter).

I flew it

And is still in one piece.

I still have some adjustments to do, but it makes the helicopter much more controllable and predictable.

Here are some pics...

Another way to throw away money

No, I am not talking about the iPhone...I personally don't want to switch to AT&T...but it is tempting.

No I am talking about Radio Controlled Helicopters. (not the little ones in the grocery store) By themselves they have some cost involved...especially when a gust of wind throws it into a tree, and you have to buy a few new parts.

But now you can buy an 'autopilot'...well actually an auto leveling/position holding system.

There are a few different styles on the market...but this is the one I am installing, getting ready to try out...

The Helicommand apparently has three axis of gyros giving input to the 'brain'. In addition it has a camera on the bottom to view tell if the vehicle is moving (drifting) or holding position. It took a week or so to install and set up (so the helicopter doesn't crash on the first try).

More later when I actually fly it.
