Master Sled builder has made an interesting point I never considered, the angle of the dangle could be enhanced to optimum angle of attack even if the bridling point is not perfect, by weight on its derriere …. as I do not have any Phillips 2000 video tape, I would have used Pirelli P6 as I have some and in the case of more wind, necessitating more tail, I would have taken a spare too and put on another Pirelli P6 to the tail to aim the sleds nose upwards sending the kite to its zenith.
Thanks for the tip, but sadly the JollyUp 9 is the last of three events, Sri Lanka, Lingfield, JollyUp9, pencilled in on my calendar to do that weekend, so will probably be missing it. ….

I was keen to make a start but Eric its designer (and good friend of mine) only got the plans to me late yesterday morning. Dick (Master Sled Builder) So the entrant will not be the designer? That must be points lost!!!!

Only 19 days to Jolly Up 9 and SLED 2 competition: it SHOULD be a good competition, Norfolk Dick was stirred (or was it shaken?) by the performance of my Paint the Sky Colours tissue sled at Sumners a couple of weeks ago, although I have to say that it does not qualify, being too small. However, I'm hoping that he HAS consulted with his friend Eric, although I think he will have to come up with something magical to beat my new design. If only the rain would stop to allow some more test flying...

Greetings Kitists,
Whilst it is hard to improve upon perfection, in order to break new boundaries one should at least try; to this end today I resolved to make a another Jolly Up Sled that would fly at an angle of elevation superior to the 83.7 degrees (plus or minus a few minutes) that my present masterpiece fly’s at.
The starting point was to examine my original sled that Eric designed for me. Upon taking the sled from it’s covering tube (sled spy’s are everywhere) I thought the kite seemed a little small; I measured it and to my horror found that Eric had only designed the kite to measure 49 centimetres.
What’s the problem you might say it is within the 48 to 52 cm rule; the problem is the kite is 49cm wide!
Frankly I am a little disappointed with Eric I showed him the rules and they are quite clear, for a man who can fly the Radical Schwitger with a helicopter and who designs state of the art communication devices using emerging technology I would have expected better. A friend of mine did say that they wondered if Eric was a bit of a vaunter and as such prone to jactitation, I told them in the strongest terms absolutely not!
So I have now embarked upon enlarging the kite by a factor of (the exact multiplier is secret) and I have little doubt it will perform as good or better than Eric’s original erroneous design.
Best Regards Dick

Greetings Roy, Because the sled is considerably wider than deep the depth (front to back) is under 48cm.
P.S. Not a breath of wind here today so testing seems unlikely.
Regards Dick

Greetings Roy & Arthur,
It would appear that we have interpreted the rules differently, I agree with what you say that there is nothing that prevents a sled of any width no matter how wide, but there is a minimum of 48cm and a maximum of 52cm which then must apply to the depth, ie the distance from the front to the rear of the sled.
My first model is shorter than the minimum 48cm from front to rear.
Regards Dick.

I am confused you have three dimensions
height top to bottom 48-52 cm
width side to side open dimension
front face of kite rear back of kite
Is Dick's kite a sled or a boxkite

It seems to me that you are relying on Eric far too much and you've placed too much faith in his abilities. I suggest it's time you started doing these things for yourself and then perhaps these problems would not occur!

The MK IIa Super Sled is now ready for flight testing at our secret testing grounds, winds permitting.
The MK I never made it to Jolly Up 8 due to a narrow wind range and resulting stability issues but in the right wind the angle of elevation had to been seen to be believed.
The MK II flew well but contravenes the min/max rule as depending on how the tape measure is applied it is either less than 48cm or greater than 52cm in length.

Greetings Sledders,
This competition is starting to take on the tones of the two Yorkshire men sketch.

Thas nothing......my sled flyed round the world twice before breakfast etc etc!

Who'd a thought 40 years ago, we would be sitting here drinking Gin & Toinic, When I were a lad, my father used to fly half way round world on his 19.685 039 37 inch sled usin jus the balin twine that he used as belt. You tell the young people that today & they won't believe you.
Cheers, Greenman
