#95518 Handle length and bend ?

Posted by Jim Foster on 04 October 2014 - 02:29 PM

The longer handles require less input to the kite.  They allow the kite to be be controlled at greater angles to the wind.

 

Some may take issue with my answer to the second part of your question.

 

The bend angle, geometrically, makes no difference at all.  Any difference in the bend angle can be compensated for by the length of the pig tails at each end of the handle.  Think about it.  If the handle was straight, you would want short pigtails on the top, and very long pigtails on the bottom.  If the handle had a 90 degree bend in the middle, below the grip, you would want very long pigtails on the top and very short pigtails on the bottom.

 

The distance between the top and bottom pigtails is what controls the amount of input required to control the kite.

 

I had Mr. Hunt for geometry.

 

We fly with fairly long pigtails on both ends of the handle, allowing nearly infinite adjustment of the angle of the grip portion of the handle.  In very high winds, we keep the grip as close as possible to a neutral position to ease strain on our wrists.

#95221 WSIKF 2014

Posted by Jim Foster on 24 July 2014 - 01:40 PM

All week, at least.
A week early if there will be opportunities to fly with other early arrivers.
You: Aug 1?  Wow.

Actually, July 31. Several Rev fliers are due to arrive in Long Beach the first week of August or thereabout. At least six. Hey, it's a long way to go for only a week. Besides that, it's a nice place to be. A month affords plenty of time to fly even if there are a few days of poor weather.

Who is coming to WSIKF to fly Revs?

 

Lynn and I will be in Long Beach starting August 1st.

 

Please post the days you will be at WSIKF.

 

Trying to get a handle on how many will be there.

 

Cheers, Jim




#94367 Lines for Rev SLE 1.5 for beginner

Posted by Jim Foster on 31 January 2014 - 10:01 AM

I would strongly suggest 100 or 120 for two reasons.
1. Line sets last a long time, especially if you are flying alone. It should be a long time before you will need to replace your 80s.

2. When you do start flying with others, you will need 120s or 100s. We use both as most people we fly with carry both. If only of the two, 120s would be the best choice. We use 100s when there are only up to four or maybe six, or when wind or space are low. Flying in larger groups or in large spaces 120s provide more sky in which to play.

Nothing cut in stone here, just the way we fly.

#93382 Revolution 25th Anniversary - 100 strong at WSIKF! (Aug 19-24, 2013)

Posted by Jim Foster on 14 August 2013 - 08:45 PM

I just wanted to say thanks to Jim, Lynn, & Bob for inviting me for a team fly with them when I was vacationing in long beach the first part of august. I had a blast and got some well needed practice in. See you all in a week for the grid, and hopefully some more team flying. Thank again, Eric the rookie

 

Eric, it was a pleasure to meet and fly with you.  See you next week.

 

Jim




#93061 Revolution 25th Anniversary - 100 strong at WSIKF! (Aug 19-24, 2013)

Posted by Jim Foster on 15 June 2013 - 04:05 PM

All kites face right. Outside kites, that's rows and columns1 and 10 move counter clockwise, rows and columns 2 and 9 move clockwise, rows and columns 3 and 8 counter clockwise etc. alternating through the grid, one space. GO. One more space, GO. Back one space, GO. One more space, GO.

Might just work. Could go three, four might be one too many for the kites in the center of the grid. I never twister more than three positions as the forth may cause a "lock" which could really cause problems in this situation.

I know you were just kidding about me calling a twister with 100 kites, but it got me thinking, which could be good or bad. That lead to the 100 kite "Super Blender" which I outlined above. Not hard or complicated, but certain to be a "crowd pleaser".


#92595 Revolution 25th Anniversary - 100 strong at WSIKF! (Aug 19-24, 2013)

I would think that many of the fliers in this grid would have flown in the 64 grid.  We, unfortunately, have a much harder time getting large numbers together on this side of the pond.  As for me, except for Kite Party, WSIKF and a few festivals, I am thrilled when I can get eight.

 

Lynn and I are ready for, hopefully, the same fun filled week as we had leading up the 64.  Flying in groups and helping to raise both the level of flying and the level of confidence of newer fliers.

 

We hate to wish our lives away, but tomorrow would be none to soon.  We plan to be in Long Beach the entire month of August.

 

Oh,,,,,, fresh 120s might be a good idea.

 

Cheers...........




#92537 Loose ferrule?

Posted by Jim Foster on 25 April 2013 - 07:25 PM

This has happened to us many times.  I believe that, over time, with the flexing of the leading edge spars during flight, the glue used in production finds it's way loose.  When I find that condition I remove the ferrule, carefully scrape off the old glue and use super glue to re-install the ferrule.  I wrap masking tape around the ferrule at the point where you want the ferrule to stop sliding into the spar, as once you apply the glue to the ferrule and start sliding it into the spar, it should be done quickly.  The tape provides a "stop" so that the glue does not set up before the ferrule is "home", or you don't slide the ferrule too far in and the glue set before you can pull back out to the proper place.   Just a tip.

 

Lynn and I do a lot of flying.  When I am washing our kites, or otherwise " messing" with them, I always pull the center spar out and do my best to try to twist the ferrules out of the center spar, thus avoiding the chance of pushing a ferrule all the way into the spar during assembly, which is a major pain, or pushing it in all but a half inch or so, allowing assembly, but after a short time it will splinter the end of the outer spar.  The latter happened to one of our team members just yesterday.

 

Hope this helps.




#92383 Line sleeving

Posted by Jim Foster on 10 April 2013 - 07:35 PM

Thanks Jim I was given mine, I knew it had to be a specific string but not being a guitar player I wasn't sure which one.

Actually, an acoustic guitar has two "E" strings.  The one you want is the smaller of the two.




#92376 Line sleeving

Posted by Jim Foster on 10 April 2013 - 01:24 PM

Tip #2. A guitar string makes a great sleeping needle. Tip #3 attach a coloured ribbon or rip stop off cut to your sleeping needle, otherwise when you put it down you will lose it.

The "E" string makes a very good tool and you may get one which has broken at the end at your local guitar repair shop.

Bend it in half and it becomes a very nice, long, flexible needle.  Cut your sleeve material about 18" long and thread it onto the tool.

Important........

   Now burn the ends of your sleeve material to stop fraying. 

Slip about three inches of your new line through the loop in the guitar string, then pull the sleeve off the guitar string on to the line.

Carefully hold end the sleeve in one hand as you pull the line back through being sure to leave about 1/4" of the line protruding out the end of the sleeve.

Tie a simple overhand knot at the end of the sleeve securing the kite line.

Hold that knot in your finger tips and with the other hand stretch the sleeve down the kite line.

Now fold the ends of the sleeve together and tie a couple of overhand knots about half an inch apart and your line is sleeved.

 

Leaving the 1/4 inch of line showing out the end of the sleeve makes for easy line length adjustment later if needed.

 

Hope this helps.




#92231 Pairs Advice Wanted

Posted by Jim Foster on 27 March 2013 - 05:21 PM

Myself and West Australian crossed lines this morning and..... it was unreal. Great fun. Even had a couple of tangles but with a bit of a laugh, it took no time at all to fix. Will definitely be doing that again. We were on 80 footers as they were the longest lines we both had. Can't wait to try 120's! It was good to be it that kind of proximity of another kite. To interact with and upon another in the air is a joyous feeling. YOU WERE ALL RIGHT, it wasn't as scary as it looked. Advice for newbies, CROSS THOSE LINES!!

Oh, dear.....you're hooked now..................

 

Enjoy the ride....




#92130 Obliviots

Posted by Jim Foster on 18 March 2013 - 04:37 PM

Wayne, let it go.  Most all of the folks who Lynn and I encounter on the beach are really nice, and are very willing to walk around, or stay back, however, once and a while you will run into that one person who will make your blood boil.  Let roll off, and just know that they don't or won't understand, and probably never will.

 

Remember......you are the one having a great time.  They are the Obliviot..
