Happy Days:
This is obviously a big model Alan. When you come to launch it you’ll want to get it out into the lift and reasonably high as soon as possible.
I wonder if you might consider it a good idea to fit a hook to the under side and do what Lothar does. i.e. Launch off the slope using a piece of bungee. That would pretty much guarantee to get your model straight out into the lift with a high air speed, thereby giving you time to get the ‘feel’ of the plane before it might start to loose height if the trimming isn‘t right.
I think if I’d just spent umpteen hours of work on a plane of that size, that’s what I’d do. I’d hate to see it go nose in, or tip stall on first launch. :cry:

If you were to launch a plane with a bungee and the trim was not right things could go pair shaped quite quickly as well. The K8 is not as big as you think it is. Not much bigger than any of Fred's machines or Joe's ASH26. All I need is a good wind almost directly onto the slope. That should do the trick, I hope. Anyway the K8 is not a speed machine. It's supposed to fly well at low speeds, at least I hope so. If it does crash I won't be too disappointed. Building it was a great learning experience. I have learned a lot of things that will make the next model I make even better.

Hi Lads. It's almost finished now. I have 99% of the lead installed in the nose. Man it took a LOT of lead to balance it. The K8's weight is approximately 5kg. Is that too heavy for a 1/4 scale glider with a 3.75m wingspan, Fred? All I have left to do is balance the wings and fix the sticking airbreaks. Here are some pics of what it looks like now.
Man it looks big
Here's a picture of my balancing devise

Alan.
It looks fantastic.
Well done.
And the new reg as well.
It will take a lot of courage to launch that off the side of the hill.
When do you think it will fly.
