Parking Brake
One is almost embarrassed to think of a parking brake as an “innovation” and not to offer it as standard equipment. But with the other makers it's not even offered. Such a brake is actually very practical, because when you start the motor you have to hold the brake on with the left hand, press the starter button with the right hand, and hold the stick with the middle hand???
Furthermore such a parking brake is a good idea for strong wind conditions on the ground. To fix the brake handle with the shoulder harness obviously is not a good idea!
We put a 3 stage detent on the spoiler/brake handle. When you pull the handle all the way back, it sets the drum or disc brake. When the handle is pushed outward toward the cockpit wall it stays in the rear-most position. To release the brake, just tip the handle inward a little.
This parking brake can be retrofitted to all existing DG-800. We offer a kit with instructions that any airframe mechanic can install in about two hours. You can also do it yourself and have it inspected afterward.
After beginning 2001 the parking brake is standard together with the Piggott Hook.
There are technical notes to retrofit such a Piggott Hook - and automatically a parking brake - for nearly all DG single seaters.

David Noyes wrote a little story to this translations which happened to his friend:
"I landed out across the road from a house. At the end of the landing roll, I crossed the road and stopped in the front yard of the house. It was rather steep up hill and I had to hold the brake on to prevent rolling backwards and damaging the tail. I couldn't get out to turn the glider and hold the hand brake at the same time. So I waited. Soon a small boy came out of the house, got on his tricycle and rode towards me. I asked him if his parents were at home. He said his mother was there. I asked him to go inside and bring his mother out because I needed help. He went in the house and stayed for about 10 minutes and then came out but without his mother. He got back on his tricycle and started to ride away.
I called him back and asked him if he had told his mother about me.
He said, "Yes."
I asked him what his mother said to him.
The boy said, "She told me that it was impossible for an airplane to have landed in the front yard and that I should go outside and play and stop bothering her with such stories."
Whereupon the boy rode away on his tricycle.
After a while the mother did come out and helped. She was very surprised!"
