I'm using the same kite to make power!!!
Hi nvmike and Inventing-man
OMG, that's an HQ 1.3m parafoil for beginners....
I joined the forum today looking for advice... take a look at what I do with this kite...
I'm going to build a remote control sled parafoil lifter type kite to lift the rear end of my generator ring up on the downwind side.
Since the keep it simple with beginner wings worked so well on the example above... I'm looking for a super stable good lifter kite... Also is there a standard control system design for kite stabilisation?
I was planning on using a single line tether ... going to a device (like a steerable car wing mirror) which can pitch and pull to the sides relative to a single tether point (front of the wing mirror) using only two servo motors...
Am I daft?
The kite power generation thing is brilliant and just genius fun.... I urge you all to give it a go.

There are several ways . One of my favorites is reeling in and letting out .
or crossing the power zone back and forth. With arms connecting like a crank on a steam locomotive.
Torque is king in power generation. Its Not so much about speed.
Dc current is much simpler to make and stored in batteries, then converted to AC if needed. Batteries present a good buffer for constant output , between lulls and spikes in wind. Pure AC would be all over the place voltage wise. .

glad you like it
Yeah, attaching the kite ends spread around the ring keeps them all flying cross wind. The main issue is automatically maintaining the ring in that position... hence I need the draggy lifter kite on the tail.
This forum has tonnes of info on power generation with kites...
Have a go

1. I used parafoils else 10 years ego...
Right now inters com back...
I made about 7-8 various of gandols...
I used two motors paragliders, paragliders w/different location of motors,
parafoil 66", where insteed gondola I used plane .40 Tower hobbico etc.
2. Right now I have many parafoils, therefore I have for sale NIB (and used Sea breaze; ~5-8 flies only)
- 55" NIB $75, (USA) ~15-20% off
- 55" NIB $75 (Europe) ~15-20% off!
- 66" (used) $100
Rogallo wing w/must (two flies) $60 ( only sail)
3. We have principle 3 systems of control: bend (left/right) all shape of parafoil, using one servo; bend left/right side sections of parafoil, using two servos
moving CG of gandola, using one/two servos
What is better various I cannot to say. May be anybody can put arguments?
About change of AOL, as far I can to suppose thamthing positive there have not...
Else question. I found out in one model parafoil (Europe), in central sections have in the back slits...
It means that air go out from sells...
What is effect I don't understand...
