A plane is a great palette  for cool gizmos. Here’s a list of some that I’m planning to include in my project:

Lighted fuel sight gauges:

Using the small, internally lighted ones, and assembled them myself. I also embedded them flush into the side of the fuselage so they don’t stick out and look like an afterthought.

Electric landing brake and nose lift:

Using Jack Wilhemson’s electric brake actuator, and will use his nose lift too. I’m following the instructions to the letter on these.
