Here's a interesting video of a demonstration of a Blade MCPX going down in Vortex Ring State. It's a small heli but it does demonstrate the effect   http://www.youtube.com/watch?v=0Kz_gOWaR7Y

New Pandora's box of 'personal' drones

They could put your mind at ease - or do very much the opposite.

A new arms race is on and it could change everything from the way we parent to how we get our celebrity gossip.

Laser Power Beaming Aimed At UAVs

Posted on May 12, 2010 at 10:00am 7 Comments

A company that won a NASA prize for beaming power to a climber in a space-elevator competition is targeting unmanned aircraft as an initial application for its laser-based technology.



LaserMotive says power beaming could extend the endurance of electrically powered UAVs. The company plans to fly a small internally funded demonstrator by year’s end.…

Yes, I rec'd my 337 a couple months ago (sometimes hard to find the 81" one either at Nitro or Raidentech since they often go out of stock)

I hope to add a single brushless motor to the rear.

I have used two EasyStars as the run-up to this, but have run out of room on them for all the video, R/C, batteries, Ardupilot, etc., so the 337 is a huge improvement.

Even though the Nitomodels 337 has tons of room inside, I found I can put the entire RC receiver and the autopilot complete with pitot tube and XY and Z sensors IN THE WING!

The balance is terribly tail heavy so my 4 batteries are hung off the front firewall as is the video TX.

I have mounted a pan & tilt camera with a ball case off the firewall as well.
I have to replace the fibreglass front nose fairing to accomadate the nose cam.
It will look more like a UAV when that is finsihed.

I plan on having 2 more cameras in the fuselage; one digital camera facing down just in front of the main gear, and a digtal cam for oblique shots out the side oif the cabin. Maybe the same one, moving it for diff mission profiles (?)

I have not flown the Cessna 337, and worry that the Ardupilot settings will be very far off from the EZs. Its not so bad when they come down, they glue back together easily, but the 337 is not so sturdy.
I have "re-kitted" many large RC planes in my years in R/C, but I hope this model fairs better.

I have been following the build threads at rcuniverse for two years now and was prepared for having to reglue most of the joints on the Cessna and add the odd extra piece at stress points etc.
I was/am surprised that the quality is not as bad as I thought it may be... in fact its incredible for $ 195.00.

Man, that is a coincidence...I am assembling it right now.

I want a single motor as well, but all my previous gas(nitro) models over the years had a lot of vibration, so I worry about having an AP onboard so I am opting for the Align 600XL in the rear.

I would like to replace the front fairing soon, but I found that the chin mounted ball cam will work with the existing fairing with a cutout and the front facing camera fits in the existing rairing as well.

I haven't done much work on my FPVs or the new Cessna337 lately since I am having eye trouble and going for surgery in a few weeks.
(actually my eyesight is the reason I got into FPV since I rekitted a couple models when I became disoriented during downwind turn...)

Oops, wrong post...sorry.

My ball cam is a Rangevideo KX191 stuffed into the glass ball from a Logitech Orbit webcam.

It is hung off the front mounted box which is an extension of the front engine mount box/firewall that I made for the batteries and video T/X.

If it works well in testing, I may not need the front static mounted cam; after all this is not meant for FPV.

Jordi sells a 2 channel video switch, but I plan on ordering a 4 channel one elsewhere. Perhaps that's unnecessary.

HI Doug, I have emailed you the code. I would have sent a compiled version as well but it's too big to email. I will upload a version to a website soon for anyone to download if they wish. Thanks, James

Hi Doug,
Could you please edit your blog post "Laser Power Beaming Aimed At UAVs", so that only a paragraph or two is quoted rather then complete story?( to avoid potential copyright issues).
Thanks

Doug,
The props I used on the quad are the standard 10x45 props from fah pah http://store.fahpah.com/ProductDetails.asp?ProductCode=ac1045bl

They are on prop savers which I added as a safety feature - they will pop off if they hit anything (the ground or me!) rather than break regards Paul
