I've been provided with the plan and a bag of bits including the bellcrank, filling valve, engine cut out and engine mounting plate as well as a set of laser cut formers.
The owner is a good friend of George Copeman and is going to send me one of Georges tuned Oliver Tigers just to check fits etc.
I know nothing about control line racing but apparently the wing can be a lot thinner and the whole model can be 5% smaller than shown on the plan and still be legal so thats what I'm going to do.
more when I make a start and get my hands on the engine

Yes a thin wing for a control line but I am a bit surprised to see it uses a flat bottom wing section.
I don't know the rules but for speed a symmetrical section of the same thickness would create less drag.
Most flat bottom sections have a adequate lift performance but the drag rises significantly at very low angles of attack.
Of course as a commission I presume you must build as per the plan.

Check that it would be 'legal' before you start!
if you are calm and collected when all about you are going berserk - you've missed something important!

George is now into his 80's and still going strong and still building engines and I've got one of his on the way to me ( only on loan but I will find it hard to resist not running it!!).

next up was the main fuse sides, took me a day to get these right, firstly I had to make a crude profile gauge to get the wing profile ( my last contact with the owner was when he sent me pre-built wing, he had it built by a guy that specializes in making them...it's a work of art..internal leadouts, hardwood edges all round and it's been impregnated with epoxy) from the gauge I could then make a template.
This allowed me to get the wing a tight fit in the sides and glue it altogether ( after about 6 dry runs and much measuring!)
next up sheeting the top..

His names Craig Simpson, goes by the name of Simo on a particular forum I frequent, I'm not the first to get mucked about by him, doubt I'll be the last.Klipkopwildlife wrote: Time to "Name and shame"?
