Kite RC conversion

Hi all
I have a couple of high quality nylon kites. I was thinking of designing some kind of motor pod to hang below to turn it into an RC kite. Anyone done something like this? Any pointers?
Thanks!

I heard of someone doing this a while back. As long as you get the CG correct, it should work fine. They just added weight to the nose until it would glide from a hand throw, then measured where the CG was from there. The only real difference between a kite and a glider is the angle of attack. I would suggest using weight shifting to turn, just like a real hang glider.

The "Vrooom Hilda" was a witch wth a cape that flew well. Can't remember who produced the kit, but it was mass produced & flew well. It was a "delta style kite". With LEDs, a sure draw from the masses! He, he!

Good fly'in,

Doug

Also have a look in the 'Similar Threads' list at the bottom of this page, there may be a useful thread there.

An Advanced Search on 'kite' also brought up quite a few threads.

Hi Niceguy,

As all Your Nylon Kites are rudderless fying objects, a conversion with an interchangeable vector power unit does make sense. Buy one vector unit, and use it for different kites.

try this:

http://www.crazyplanes.de/specials (he did a lot of rc-kite conversions)

or this:

http://www.horizonhobby.com/Products...rodID=PMR10292
They offer interchangeable vector propulsion power units for vector kites, useful as well for any kind of kite-conversion.

That's a good idea. Is that basically a pan and tilt system? Is there some kind of buffer to save servos from stripping?
If you were to make one, I guess you could use strong servos, and give them leverage by long sticks as control "horns"?

... watch this:

Premier RC - Vector Kite Gimbal.mpg (1 min 30 sec)


Here You can see, how the system works.
If You want to learn more, google for ' vector kites ' - there are 50 videos showing different Nylon covered Vector Kites.

Thanks for teh interest Flatterman.
Ya, that's just a heavy-duty pan and tilt system. I could definitely make that.
What limitations does this method of controlling a kite have?

... as the vectorized kite is rudderless, You should look carefully at Your LiPo capacity during flight - You only can steer the kite with the running motor.

A Vector Kite's glide is steerable only with motor action. When I go outside for Vector Kiting, I always have some freshly charged Lipos with me.

How about adding a rudder to be used on the rudder channel? Motor can be used as a supplement during glide.

Actually, what's the reason for the complexity? What happens if a traditional rudder/elevator are used?

BTW, this guy has got some kind of wacky CoG shift mechanism. Looks difficult/complicated to make, not sure how it works.

... rudders belong to airplanes.

Vector kites don't need rudders.

Piloting a vector kite is RC-experience like no other.

Can you give me some specific reasons for that? Or are you not sure yourself?

Hi Niceguy,

Do You remember the theme of Your thread?

As I understood, You wanted to converse Your '..couple of Nylon Kites' to RC-Kites.

Of course, there are several ways to do that.

Converting Your kites with a Vector Unit is one possibility - and new technology.

The only advantage to combine a Vector Kite with rudders could be, that Your converted kite is able to have a controlled glide, when the BL-motor once stopped.

One of the most fascinating experiences You can make with a Vector Kite, is:

The slower You fly, the higher the maneuverability of a Vector Kite is. By that reason, You will love it to fly especially Big Vector Kites quite close to You, indoors as well as outdoors.

Thanks for the interest.
Obviously I doen't have any knowledge of this topic. So I want to get educated.
I still don't know the fundamentals of RC kite dynamics.
For example, What are the pros/cons of a fixed motor with traditional rudder/elevator? CoG shift device?
