Okay, I'm just going to throw this out there, folks. There are some interesting, and pretty nice looking panel designs in this thread.
One thing I'll add as a cautionary note, though:
If you mount ANYthing that protrudes from or above the instrument panel of a Cub, it could turn into a lethal instrument in an accident.
A good friend of mine was killed in a Super Cub many years ago. The proximate cause of death was a Garmin 90 that was embedded in his face. He had other injuries that likely would have killed him as well, but...... That Garmin 90 had been mounted on the left windshield post. The stall/spin ended in impact which threw him violently forward and left. The pilot was wearing seat belt and shoulder harness, but there's no way to know how tight they were. And, I'm not suggesting that he'd have survived if not for that GPS, but.....
A year ago, I was in a left turn lane in my Honda Ridgeline here in BZN, in line behind another car. I was hit from behind by a gent who drifted out of his lane, and impacted my car at about 50 mph.
My airbags did not fire....not sure why, but the only injuries I had were very sore ribs and hips from belts, and a very fat lower lip and left shoulder where I impacted the steering wheel. This apparently on impact with the car ahead.
My point is, your body becomes very fluid (your body is, in fact mostly fluids) and belts, even fairly tight ones, may not prevent your head and shoulders from coming quite a ways forward.
For that reason, I won't fly an airplane with "stuff" protruding from the instrument panel. Of course, your face may still come far enough forward so as to impact the instrument panel, but......why make it easier to impact installed equipment?
Please give this some thought when equipping your airplanes......GOOD shoulder harnesses and seat belts can save your life in an impact, but your body, in a severe impact, is going to move around a lot, belts or no.
