Parawing *TOP SECRET*
Hehe well its not top secret as you can see it in recent changes - oh well…
I'm just going to dump everything i can think of/remember:
Things that need to be done/overcome/worked out:
- 2 way comms
- kite dynamics, e.g. winds, angle of attach
- deployment at altitude e.g. cutdown, drogue? predeployment? parachute for most of descent and then use parawing later?
- pathfinding - ability to calculate best angle of attack into the wind, not risk parawing by going directly into the wind, find alternative landing sites?
- kite shape - enchanced or not?
- control, method of turning, servos + bar, motor + drive shaft + t bar, winch + bridle
- flight computer - gumstix for gps, digital compass, complex pathfinding, comms + PIC for controlling motors/servos + sensors?
- landing - autopilot? r/c guided?
- future plans/roadmap
Specs:
- 750g payload
- therefore 1m2 parachute would be required
- equivalent parawing?
Ideas:

- Slope Soaring Sim (Free flight sim for mac and windows) Link
- Feedback from MC: If you want to split up tasks, I could work on 2 way comms.
Parawing won't mind going into wind, IMHO
I think the Mk1 version could be steered from the ground, then Mk2 could be steered by software
It should be possible to have a much smaller payload, perhaps around the mass of a servo+batt+electronics, 200g? ed: - Although reduced weight is a good thing in general, weight will help us control the wing. Also, when you factor in cameras and the actual mechanics, 750g seems like a more realistic target to me- we'll still have to be building light to get it in under that!
