Design Improvements for the Zenith 601 HDS: Gust Lock
We use a small gust lock that fixes the center stick.
It is made from two 3/4 X 3/4 X 9 in. L
pieces and a short segment cut from 2 in. ID tubing.
The tubing segment is riveted to the L
pieces. The inside of the tubing piece is covered with neoprene
so that the lock does not damage the paint of the control stick.
One of the L pieces has a sliding
1 X 1 X 1 in. block made from L material. The block is attached
by an AN3 bolt and nut. Finally, a 1/4 in. pin, about 4 1/2 in. long,
The gust lock is installed as follows.
The lock is placed into the channel formed
by the two L brackets attached to the main spar and holding the
bearing of the control stick tube. Next the pin is inserted.
It goes through the two L pieces of the gust lock and the two L brackets.
Finally, the block is pushed down and thus presses the tips of the
L pieces against the L brackets.
This holds the gust lock firmly in place.
