... you realize you are trying to fly the handles of the elliptical machine at the gym.

... the last thing you remember before falling asleep is how you held your handles when you worked on your inverted slide.

John,

If picking up the handles makes you nervous, consider using two stakes. One, it will keep you from inadvertently pulling one handle through the lines of the other handle and second, it will allow you to pick them up one at a time which makes launching even less likely.

The other way to overcome your concerns is to lift them hard off the handles with brakes fully applied and you will see the worst that might happen is an extra walk of shame. Unless the winds are 20+ mph, and you fly with little or no brake, the chance of a self-launch is low. The good new is that you really won't hurt anything if you do launch. In two years of festivals and flying, I have never broken a spar and know only a few fliers that have actually broken one. Those fliers have lots of years and do lots of tricks and flying that can stress the spars. Not saying it can't happen, but it seems a lot rarer than the concern.

Check out the amount of brake you are using. If you don't have to give a decent tug to launch, I suggest using more brake.

Good winds.

On the same page as the drafting tubes were nylon bags, 39" x 5 ", 2 for $5.98

Room for a kite and another set of spars or handles. Also would make a good "quick kit" for the trunk.

Rigster,

Any recent flying attempts? I'm missing the sunset pictures. Posted Image

Flew this evening - I'm discovering that my wind window for learning is not as wide as I'd thought. Yesterday it was howling so I gave it a miss - tonight was a return to light & gusty but I had to try again. My diagonal take offs I'm now sure were a combination of too much right thumb & an off centre wind. I tried having the 2 handles against each other with the wind directly behind me & it went straight up - I'm guessing that means the lines are as near the same length as makes no difference? Once again the opinions of others on here was spot on with the diagnosis - thank you. You are probably right that lines are equal. It's still worth checking. Use two ground stakes (or screw drivers) parallel to each other in the ground. Unwind line sets and hook left loops on one stake and loops of right side on the second stake. Unwind lines, pull taught, and check all are equal. If you wife will help out, you can do on fingers and see if one line droops more than the others. This way is easier to see.

One habit I'm struggling to break - and only I can make it happen - is that when the kite is in a death dive I keep yanking my thumbs back to make it stop, with obvious consequences. Once this evening I did make it stop before hitting the ground - I nearly jumped out of my skin - it was wonderful to see. Unfortunately I was so excited about stopping it cleanly I forgot what I was doing & accelerated it from hover the remaining 10 feet straight into the ground ... at least it gave my wife a laugh. Dual line habits die hard! Posted Image. You need to build muscle memory into your thumbs. You can build it by practicing starting and stopping on the way down. Go to top, do 180 and then slow it down as it comes down. Play with rocking thumbs forward and back to get the sense of stop and go. You can do it on the way up as well. Adding more brake will definitely help here! Your "neutral" position still has lots of forward and is added to gravity when leading edge is facing down.

I spent a while this evening trying exercise 3 in the "handbook" - the hover on the wingtip and horizontal reverse flight. Pulling back on the arm with the upper wing felt alien & I couldn't make it happen - it fell from the sky like a stone. I would make it stop while in forward horizontal flight & it was as if it lost the will to live and decided to give plumetting a go. This might be due to low gusty winds, especially close to the ground. Is there a "knack" to this that I just need to discover or does anyone have a tip on how to do this cleanly? Is it reasonable to be trying this on a 3rd flight? Presumably a decent breeze would make it easier? Not sure what exercise #3 look like. Pulling back on an arm is causes a slide. Check out this link for Rev's suggested exercises. http://www.revkites.com/main/Techniques_1. It sounds like you are trying to do their #5 which is a slide + horizontal flight. Suggest doing slide later after you have more comfort with basics. Try horizontal figure eights and experimenting with fast, slow and stop. Reverse is extremely sensitive. Too much reverse and the kite starts flapping madly and/or does a bow-tie (twisting around the center)

I think I've underestimated how much breeze my kite needs to fly cleanly & how much it will take - what is peoples' opinions about the strength of wind the 3 wraps on an SLE will take before it gets iffy to fly? I'm getting an idea but it would good to hear a seasoned veteran's opinion. 8 to 12 mph is a sweet spot for learning. I think 12-16 mph is comfortable for sail and spars depending on how gusty the wind. More experienced fliers should chime in. It's more about sail stretch than spar breaking. It also depends on the moves you do and how stressed the frame will be.
Attached should be a couple of pics from this evening - it was getting dark again as we left but the sunset was mesmerising. (I've tried several times & I can't seem to get them to upload - they're about 700k each)

Thanks to everyone for your ongoing patience - I will get the hang of this eventually & then leave you be.

Found the way to host the images:
flight 3 -1
Flight 3 -2 Picture looks good. Hands close together and appear even with each other.
flight 3 -3



Getting the muscle memory and the sense of how little is needed to control a Rev will really help when you try the more complicated moves. It may seem a little boring, but the practice will pay off big time.
