Default 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.

Default 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 doesnít seem very aerodynamic, lots of guys put them outside their airplanes, and I donít believe anybody makes one.

Default 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.

Default Monopole Fairing?

How about a 2-piece fairing for a monopole antenna to convert it into a blade type?

good idea. appreciate the comment. I made one from foam and duct tape years ago but it was only good for about five flights.

+1 For the GoPro fairing. I have the camera mounted with a PlaneAround mount using Wing Tip screws. Works OK, but I think a Fairing, particularly if it were isolated from airframe (and aerodynamic) vibration, would be fantastic.
