 20th Ike

Dear Martin,

Thanks for your last e-mail. With respect to towing hardware, I attach a number of photos that detail a very effective straight tow mechanism for training purposes plus an explanation.

I believe this design meets the high expectations of future sports FF who require gear:
* that looks professional,
* is reasonably priced,
* or is easy to make
* is relatively fool proof
* plus a design that gets them out of "coffin Corner" when everything goes horribly wrong!!

I am copying this to the Sage at Scat, just to gently counter his well meant comments in NFFS, about the lack of effort on the part of the Brits to stimulate Junior interest in the UK. The answer is Roger: just ignore the "not invented here Brigade", to steal good ideas from other successfull sports and hobbies that continuously regenerate membership. Committees that concentrate solely on technology and competiotions do so at their peril. Successful hobbies/sports is about being competitive in the market that matters -that is why kicking a blown up plastic bag - sorry soccer ball - is so popular.


Back to our initiative I am sending you pictures of Vasily Beschany's

Dear Rev SCAT

Apropos Karl Hube's request for more info on Andy Crisp's windy weather
gliders, he could do no better than to buy a copy of 'Andy Crisp's World of
Model Aircraft'. This contains dimensioned drawings and full size airfoils
for circa 10 F1As from the Flashback onwards, as well as A/1s, chuckies,
coupes, F1Bs etc. Andy's lower aspect ratio models are still doing the
business, and but for an injury suffered while towing during the final
round, he would have maxed out at Poitou this year.

The book is available as a down-load for a modest sum from:

http://www.instant-books.org/product?id=21

You may have published this in a SEN issue before, but time dims the memory.
I'm not associated with Instant Books in any way, other than to enjoy the
odd glass (or several) of Merlot with the chaps sur le continent!

Yours obsequiously

Peter Tolhurst

Ps Merry Christmas & a Happy New Year
