kA3 1/2 SCALE

Hi all, well I've not done this before so here goes. I started this project 2 1/2 years ago and it has been on and off eversince, I enjoy building and the challanges it brings. This model is based on a plan drawn by Cliff Charlsworth but beefed up and modified as required. As luck would have it where I work here at RAF Cranwell the Gliding club has a K3 in the hanger so I could visit as and when I wanted .

Wow Zob, as I already said, very very impressive !

Do you have more pictures of the real one ?

I cannot find enough documentation for this glider, other than what I've found in the scale soaring U.K website...

Ok guys, I weighed the finished model today and it came out at 40lbs which I am happy with. and I have balanced the model at 25% of the cord to start with.
Fred i will put some photos on your thread of the real glider. Hope you like the next set of pictures.

Very impressive! I can just imagine what everyone had to say when it was assembled on the deck for the first time!! 40lbs might not be enough, you may need to add some ballast to get it to penetrate.......you'll know after that first flight ....25% is very conservitive on the CG....a good place to start.....I would guess that after you have flown it for awhile that will move back.....I started with 33% on my SZD-16 http://www.rcgroups.com/forums/showt...4&page=8&pp=15
and will be taking some out the next time I fly. Keep us posted as to the first flight......

I was just asking out of curiosity....
I worked in general aviation maintenance for a long time, worked on almost everything from single engine Cessnas to Citations, Lear Jets, King Airs, etc.

Never got my hands on a Hawker, though.....

By the looks of the exhaust of the engine, your Dominie is the older version, with the GE CJ-610 turbojet ( no fan) engine.
We used to call them fuel-to-noise converters....
