no longer an issue

I have a lot of fun playing with the 3d printer, it also really can push a guy close to insanity.

nice work Don.

I have an antenna that looks like this.

How can I make it look more like this and gain a few knots?

or this?

Good idea Steve maybe if you would model the antenna that you have then give it some Clarence and make a fairing in the shape that you want around it. Basically a hollow fairing slipped over the existing antenna and use the same mount holes to secure it.

didn't find much. not much of sweep on this antenna.

I'm on the road & can't find the reference, but take an imaginary slice through the antenna shaft, normal to the air flow. It will yield a section fairly close to a streamline, or teardrop, without the pointed tail. Not perfect, but much lower drag than a cylinder. IIRC, that's why they are swept.
 
ok, I understand the concept. thanks.

data from the website.
first antenna
The antenna is designed to operate at speeds up to 350 mph and altitudes of 50,000 ft. It has a drag force of 3.43 lb @ 250 mph

second antenna
The antenna is designed to operate at speeds up to 350 mph and altitudes of 50,000 ft. It has a drag force of 0.85 lb. @ 250 mph.
 
Bose headset volume controller cradle....

Can you make these in a Left and Right? I would buy a set!
 
I have a PRUSA style printer as well and have been making all sorts of things with it for around the house. I gone through miles of filament so far and my print time is somewhere around 20 days, I have only had it for 2.5 months...haha.

All this antenna talk has given me some great ideas for the plane. I think my X-Ponder antenna is about to get and upgrade. I may just print a mold and make the part from fiberglass, we'll see.

Next, I want to try using a printed part in place of wax for a lost-wax type aluminum casting.

3. Bose headset volume controller cradle. I fastened this to the side of the cockpit. The arm hanging off to the side is just big enough to hang the headset on when I'm getting in and out of the cockpit. I mount it just under the panel elevation so I don't snag it on my leg. I also have one for my Zulu headset. The controller easily comes out for battery changes:

Here are a few of my 3d printed accessories - all in polycarbonate and printed on my home brewed Prusa i3 style printer. 3d modelling is in solid works, and I use both Cura and Slic3r to output the machine codes:

1. This is my overengineered drink caddy. It also includes pockets for sunglasses, two usb thumb drives, and a miscellaneous slot that I use for keys and/or usb cables. The vise grips were for a temporary fit up. I've replaced it with 2x #8 screws/platenuts since this photo was taken.

2. Replacement battery box for my EarthX. On top of the weight savings of dumping my PC680, I realized that the aluminum box that came with my -6 kit weighs a lot too. This one checks in at around 1 pound.

FWIW, all three of these links are dead now.
 
Idea

Anyone doing spats for the hinges on the RV-10 flaps? Looks like an area just begging for some articulated fairings.
