Stick Grip

This blog covers the details of the installation of the stick grips.

Overview
This aircraft has to have a military-style stick grip, and the only choice was the Infinity grips, luckily a pair was purchased locally new but unused at a reasonable price.

It was decided to integrate some of the features by RS warbirds in the USA. One of the details was the ring below the grip - yellow ring in the image and was machined from ABS plastic.

The final location was determined, this involved reducing the length of the shaft at the stick mounting to lower the grip. Once satisfied, the collar was secured in position using a single black 1/8 x 6 mm pop rivet.

The cables were wrapped in a PPS tube, run through the control stick and out using a slot cut in the tube before installation.

The cables were now run and secured to the airframe will all control sticks terminating at the junction box located on the starboard side of the pilot's cockpit. Both sticks end in this box with the pilot able to control flaps, boost pump, transponder ident, trims, and mike. The co-pilot lacks the transponder control.

The grip was secured at a slight angle, it was noted that when the grips were tightened, they were loose, so the area above the collar was wrapped in one layer of gaffer tape that was folded into the tube providing a rudimentary anti-chafe for the wires.
