I would like to participate in this competition as a team, with my daughter. i live in Scotland and will build the kite. She lives in Basingstoke and will do the flying on the day.
This would require a liberal interpretation of Rule 2: "Each kite must be made by the flyer." But we are probably within the spirit of the rule in that it will not be a commercial kite but rather, a home made kite designed and tuned to improve the state of the art.
Would this be permitted?
Andrew

I am prepared to say yes, as I want to push sled design further, too, but if I receive protests, either beforehand or on the day, I may have to exclude it: provided you are prepared to accept this risk, then go ahead.

I was amazed by the pull on Batchoy's sled.
That is until the tail let go.
With a little more strength in the tail that could enter a beer lift!

The failure in the rear tie was the result of a design flaw which led to a stress point in the mylar film and hence the propagation of a tear. This has been corrected for the Mk.6 which is also getting a revised centre bridle to ease trimming and a slightly increased aspect ratio for even more lifting power. Prize wise My Mk.5 got the Most Original Design award Dianne Butler got Prettiest award Siobhan (using a kite based on my Mk.3 plans) got the Best Overall Award and the Cup  |

STILL no REALLY well performing sleds, come on, get experimenting: looks like Guy's getting sorted for August... |

Andrew Don't remember seeing someone who could have been your daughter either day Andrew? Or did you just decide against? I think that there would have been little problem, knowing those who actually entered... |

Is there any fool person out there who fancies that they could do a better job of judging than my poor efforts? Just asking...

STILL no REALLY well performing sleds, come on, get experimenting: looks like Guy's getting sorted for August... To help people along here is my Mk.3 plan that Siobhan used. Sled-Mk3.pdf (1.05 KB) Mk.3The plan shows half the sail, it is an open class sled as it has 3 spars; one each side in the normal positions plus a central third spar. The kite is a tail less design but stability can be improved by turning it into a Mk.4. Mk.4The Mk.4 shares the same sail as the Mk.3 but has two ties at the tail end. The first links the tail end of the two outer spars and draws them together, the second links the same two points but goes via the tail end of centre spar allowing it to be drawn down adjusting the angle of attack of the spar. |
