Re: AUDAX
The stab tube sleeve was attached to the fuselage with epoxy and microbaloons. The stab key is made of 4mm diameter aluminium and passes through a carbon tube glued inside the fuselage so it can be replaced if necessary.

Wing and stab root blocks sanded to fit the fuselage:

Hello Alex
Wonderfull wings !
Any informations and experiences about servo Hyperion DS 20 FMD ?
This servo is not expensive, price is about 35 E in France

Re: AUDAX

The metal gear Hyperions are very good servos, just stay away from the carbonite gears.
The Hyperion DS20 FMD is ok, but i prefer to use the Hyperion DS20x-SMD (coreless servo) for ailerons now because it's a little faster. I bought them from http://www.makrisrc.com in France.
For elevators i use the DS16 FMD, but for rudder i chose the Futaba BLS 452. I also tried the Hyperion DS20 UMD for rudder but it seemed to lack
resolution. All the other Hyperions don't seem to have any problem with resolution.

Re: AUDAX
After some thinking i decided to give up on the idea of having the elevator servos hidden inside the stabs. The thickness of the nut, servo arm, spacer, ball link and the screw head are all adding up, so the slot required for the free movement of the linkage would be very wide. For me this defeats the purpose of having the servo hidden inside the stabs.
The other alternative would be to use a very long servo arm and small servo travels so the ball link doesn't interfere with the stab underside, but i didn't want to sacrifice servo resolution.
I decided to install the servos on the stab undersurface so i had to improvise something for the servo mounts. Too bad i didn't think this through from the start because it would save a lot of weight, probably around 15g for each stab.

Re: AUDAX
Before film covering, i assembled the model and took a few pictures. I'm not sure the pictures can reveal the size of this thing, so here are a few dimensions of the model. The wing root chord is 580mm which i believe is larger than anything out there at the moment. The fuselage is quite tall at approx. 380mm in the the canopy area and the fin is 455 mm tall. In general it seems huge and i barely had enough space for assembly.
