small button on rudder clevis fairing. we will see if it survives flight testing. needs some adjustment.

tail tie down fairing is looking better. contoured fit.

rudder clevis fairing
 
button added and flight tested. it's small but workable.










trim the long side of the cotter pin as the one next to my finger

rudder clevis fairing
 
install nut using the printed tool. tighten the nut to the cotter pin slot past contact. that's all that is needed. this was my original nut installation method without fairings. no change.


position the cotter pin long side up














lube at provided hole. the lube track extends under the bolt head to the bolt shank, where it is needed.

tail tie down fairing
 
grey to be a different color from the white wing tie down fairings. I'm not sure how I got that little chip in the side of the fuse but it's bugging me.

Nice!
 
Nice work Steve! Thanks for continuing to bring nicely engineered pieces to market.

rudder pedal extension
 
sketching out. these first trials are going to look like the JDAirparts version to get a back to back weight comparison. JDAirparts rudder pedal extension = 72 grams.

option 2 could be a single bar version so that it doesn't trap mud.

option 3 could be multiple length extensions for a custom fit. such as distance from the bar... .5, .6, .7, .8. the one in the photo = .52 inch.

option 4 could be making these over center for a snap fit than then clamped with bolts. a safety feature.







over center snap fit with 10-32 self locking nuts




no mud version, these will be printed hollow with internal reinforcement for both strength and light weight


extended version, .65 inch from bar

A fairing similar to the other ones you have made, but for a GoPro would be awesome. The GoPro cube shape doesn?t seem very aerodynamic, lots of guys put them outside their airplanes, and I don?t believe anybody makes one.

Another 3D printing idea
 
Here's another idea if you are interested:

Get the dimensions of Pat Hatch's "The Ultimate TRB":

http://www.phaviation.com/?wpsc-prod...timate-trb-hub


Print a box with the following characteristics:

The pc board sits in the box such that the connectors are exposed out the "left" and "right" side of the rectangular box, but the rest of the PC board is in the box.

The main "container" has 4 holes in the bottom which line up with the 4 mounting holes on the PC board. The main container is mounted to the airplane with 4 screws going through the PC board; through the 3D box: through some sheet metal and into nutplates mounted on the backside of the sheet metal.


The flat lid faces out, is fastened with 4 screws, and is removable without having to remove the PC board from the airplane.

The holes for the connectors on either side can be open to the top edge so that the PC board can be easily removed and replaced if necessary.
