If you fly FPV indoors in different lighting conditions with Fat Shark Attitude V2 with faceplate, Attitude V3, Spektrum Focal V1 or V2 goggles, you know how often you have to fiddle with the brightness knob. With the fan and switch so close together, it’s obvious the fan was an afterthought. Even a person with tiny fingers would have a hard time getting in there to move the knob outward away from the fan. So I came up with a simple solution that involves only a short piece of heat-shrink tubing. It’s now much easier to operate the Display Control knob on these FPV goggles.
Display Knob Extender Installation
The small semi-square Display Control knob on these FPV goggles is removable. The backside of the knob has a square recess or socket that mates to a square shaft on the switch and just presses together. I removed the knob and installed a small piece of good high voltage heat-shrink tubing. Higher voltage is stiffer when shrunk down so it holds its shape better and won’t collapse when pressing down. One thing you do need to watch for is that the tubing is not too thick to inhibit movement within the goggle body. There’s only so much room between the knob and hole so you can’t go too thick. Another option might be to glue or insert something in the tubing before shrinking to make it stiffer. I wanted to keep it kind of flexible for when it gets bumped.
