Default a couple printed ideas

rocker switch protector. use small velcro on each end to secure.




infinity stick cover. first trial.



looks goofy, works great. no more snagged switches when climbing in. that could ruin your day. just drop it on and it finds the home. done.







label embossed



print with multiple colors and glow in the dark plastic?




label recessed

Default fuel drain fairing

maybe a little proseal on the cylinder is enough to adhere. weight = 16 grams. first trial, size is not final. plastic cost = $ 0.42. may also improve the life of the o-ring since it will eliminate vortex shedding vibration of the stem that is in the airstream.

Sweet, I will take 2 of the fuel drain fairings, where do I send the $0.84?
How about a smaller fairing for the fuel vents on the belly?

I'll throw a couple of these in a back for Oshkosh. Fly away with a "faster" airplane.

Default Fuel drain lock

On the fuel drain fairings could you put a hole in it such that a small lock can be inserted so that it will prevent someone from stealing fuel? I dont know why this occurred to me, not that i live in LA or anything like that.

John, I wouldn't do that for anyone except you. Let me know when you need it. Steve

From concept to holding in the hand in about two hours and I had to watch a youtube video for training. I am still amazed by this technology.

I see Solidworks can complete CFD airflow analysis. I'll post a couple slides of that. Not that this simple fairing needs any analysis but just to share. Maybe someone can chime in on that.

My youngest daughter, 9th grade, runs circles around in solid modeling and is beginning to talk about stress analysis. Now we have something to discuss!
