First, clean any grease and grime off of both sides of the banding material. I use acetone. Kept in that green bottle, nobody has ever accidentally drank some. -

Spray sandpaper, and banding strap material with 3m77. -

Let it get a little dry then glue the sandpaper on. -

Slice it free with your razor blade, and the look you there! A flexible sanding stick! -

The strapping material is easily bent for tight places.

First layup in the newly completed fin mold. Notice the CF braided tube on jumbo straw mandrel. -

PVA mold release did the job.

First pass was a 1/2†ball nose, leaving 0.030†(about 1mm) for the finish pass. -

All the curved surfaces in this mold were finished with a 3/16†diameter ball nose mill. -

After the roughing pass, I painted it with machinist layout ink. This will help show the cut- machine away the blue part. -

Finishing pass is 6000rpm at 50ipm with a 0.003 step over. -

Finishing pass took about 3 hrs! -

This is my basic link design. Stainless steel, not plastic. 1/16" precision hole has sweet fit on SS dowel pin. -

4-40 threads, cut a little fat for a nicer fit on Sullivan clevis. -

Different lengths, the 2 top ones are for the Kinetic. You can see how short a pushrod can be made. -

Same kind of link, only this one has 4-40 female threads. -

I had to put them together... This could also have possibilities. -

This is the beginning of a 3.5mm arm for the Kinetic elevator servo. You can see Spencer's 2-56/CF pushrod screws right in. More work yet to do. -

This is the 9mm flap arm. -

I'll be able to lock out my flaps with the pushrod across the hub at 180 deg.

Not much room here for 7 servo leads. Some pinching likely -

Airtronics10 ch rx was a tight fit here where the voltage regulator now lives. Note Deans plug instead of switch. The idea is to not have narrow current 'bottlenecks' like a switch might be. -

Plenty of room for the VR. -

I shortened the servo leads from the green Multiplex plugs. I can fit a RX in thru the joiner hole into the space between the LE holes. (former location of voltage regulator) -

Notice the double red and double black leads. A jumper connects the other red terminal on the plug. -

Same kind of thing for the black wire. (small jumper) -

Each multiplex plug has a red and a black wire running forward -

to the voltage regulator and small Deans plug used instead of switch. This means the wing servos do not draw their current thru the RX buss.
