    Kitesurfing, landboarding down hill or with kite, RC gliders, skate boards.
  1. @nigel is that because you would then have to kite surf? Come on guys, help Alex along here and encourage nigel to kite surf, you all know Alex would be tickled pink.
  2. @Grants when we moved from Oz to NZ, we had to not only declare what we brought but how we cleaned the items, imcluding cars and landboards. I popped the tires off all of my landboards, removed all seeds, sand and dirt; then assembled them again pumping up to normal pressure; all this declared for the customs to read; all went through without any trouble. Kites received the same treatment, I was very particular to remove seeds from the velcro straps, inspected the internal spaces of the kites to make sure all seeds removed, again all stated on the declaration, all kites went through without hassle. Don't forget your kiting harness and body guards, they great traps for seeds -- after I cleaned these they looked like new Hey @Chook did you do similar for your recent holiday?
  3. eew, I saw the post whilst having breakfast and figured, I definitely don't that. Glad I did not press the play button.
  4. Nice video, looks like you had good weather as well. Crab holes made for a bumpy ride.
  5. I think he needs one of those Born-Kite single skin one handed bar kites the StreetStar
  6. Great story Chook and loved the music. Dig the guitar player with his elastic side boots. Good one you Mrs Chook.
  7. Interesting concept. For riders of uni-directionals, spend a lot of time riding one handed anyway like when going toe side, using the other hand for extra balance control and just plain puts less twist on your spine.
  8. If you are really in a bad state needing medical care, waiting time can be a big deal. I would shop around to see what the various insurers provide and read the small print.
  9. Have you tried sourcing the cloth from Peter Lynne here in NZ?
  10. That is why I am very cautious with upgrades on any of my computers, I prefer to use them for the fun things and not be plagued with fiddling with software to get it to work -- PC or Mac. But I guess some people like fiddling.
  11. You forgot the operating system costs, that comes with the Mac.
  12. The temperature variation with height is included in the equation. The weather maps give the temperature at a specific height, the equation then provides the distance above that height for the cloud base. Wind, hm no account for that, ie low rolling fog over the ocean which then gets convected up the mountain side. So far the equations follow observations here where I live. Yes do remember reading the theory on it all and them saying a lot of simplifying assumptions were made. Hopefully the local weather conditions on the weather maps iron out a lot of those extra effects. Had an idea you would pop up and comment @Chook. Must be an important consideration for your flying, how do you do the predictions? Just looked at the definitions, adabatic is for wind generated by warm air rising up the hill, katabatic is for cold wind flowing down the mountain. Yes must agree the formulae do not account for this. Since I am interested in wind up the hill, if the predictions from the bottom of the hill show cloud base where I am interested in, the conditions at elevation I am guessing will only be worse. But then there are the conditions where at lower elevations there is a thick fog or clould layer and further up, it's all free with blue skies but how mich further up is the question.
  13. Ever wondered how to calculate the height at which clouds may form? So who ever wonders about this? Pilots of airplanes do or some one wanting to fly their RC glider up in the hills. So here I am waiting for the weather to clear ready for some slope soaring, have from the local weather maps data on air surface temperature and relative humidity at various locations. Can visually see some of those locations from my place but not all of them, so no point in driving out to those places if they are all fogged in. So off to do some research on how to perform such calculations. By they way, very difficult if not impossible to fly white planes on a back drop of grey fog blasting up the mountain side! So here is the theory then plug it into a spread sheet on my ipad Being the eternal optimist I put in some what if scenarios to see how the height changes as the humidity drops. So if the humidity drops by 10 percent the cloud bases rised from 138m to 322m, almost flyable for the location I have mind. Odds are the temperature is not going to change much, so all I need to do is scan over the relative humidity maps for my target value, then it's off to the hills for some flying, well that is the plan. Could rain though .... arg ... but hey that brings snow up in the big mountains
  14. We are getting all excited about the snow season across the ditch in New Zealand as well, resorts open next weekend, same deal lots of outstanding jobs done, season pass purchased months ago.
  15. Thanks @plummet was thinking the same, either way it gets me all fired up on the subject. Whilst we are on the subject of anhedral, on all the wings I have looked at or read about, planes or birds, it causes an instability translating to quicker response but needing more skill to fly. I thought perhaps the anhedral was to avoid the wing breaking the top water surface during heavy up wind tacks, and would allow the rider to be less locked in for rolling action, ie too stiff against roll without anhedral. I have seen commercial designs mostly with anhedral on the front wing, some dead flat. Can see the dihedral on the back wing being benificial for stability though. Or is the front wing anhedral so the rider is less likely to slice a foot with it pointing down instead of up?
