NEW "STICK SHAKER" DEVICES INSTALLED The Boeing 767, like many other jet aircraft, have shaker devices mounted to the control columns. These devices, better known as "stick shakers", aggresively vibrate the control column to immediately alert the pilots of a stall situation. Of course we just had to implement this into our simulator. So we contacted Ralph Robinson of R&R Electronics with our idea. Combining our creative resources, we came up with a very easy and cost effective solution. On this page we will share and outline how we made our "stick shakers". Hopefully other folks can copy or draw from our idea. Entire cost of the implementation was just under $7.00 US dollars. Total time - Roughly 2 1/2 hours for (2) devices.

For our "stick shakers", we used (2) Radio Shack motors (part# 273-255). One for each control column. These 12V motors are inexpensively priced at $3.39.

STEP 1 You will need some kind of a weighting device attached to the shaft. In the photograph to the left, you can see we are using a small rubber disc. Nearly any kind of material can be used just as long as the weight is not too heavy. A hole must be drilled in the weight so the shaft can slide through. Make the hole one size smaller than the shaft so that the weight remains snugly on the shaft and does not vibrate off. You must offset the hole to achieve maximum vibration. Consider what your car would feel like if one tire was off- centered. Bingo! It would vibrate that hell out of you.

STEP 2 Firmly press the weight onto the shaft as pictured left. Seat the weight near the bottom.

STEP 3 Attach and solder wires to the two leads.

STEP 4 Manufacture some type of mounting bracket which will hold the motor in place. Here we a cut thin strip of aluminum sheeting for our brackets. Whatever material is used, it is imperative that the mounting bracket hold the motor firmly in place.

STEP 5 The next step is to mount the motor to your control column. Real aircraft normally attach these devices near the bottom of the control column. Since our motors are much smaller than the ones found on real aircraft, we chose to attach them directally to the yokes for maximum vibration. If you choose our method, make sure to cut out a small groove for the weight. Since the weight is off-centered, it will smack the mounting surface if this groove is not made. Be sure to drill a small passage hole for the two lead wires which will run down the rear of the control column.

STEP 6 Mount your map clip over the motor to conceil it. We cut a small piece of wood and attached it just under the motor. The piece of wood, just slightly deeper than the motor, allows for easy attachment of the map clip.

STEP 7 Cut a strip of aluminum sheeting and wrap it over the remaining section of the exposed motor to totally conceil it from dust and dirt. Eventually we will paint it the same color as the yoke.

And thats it! All that is left now is to connect the two lead wires to your Epic output module.   SEE EPIC TOPIC FOR CONNECTION DIAGRAM
