Skymaster Viper Assembly
I've started assembling the Viper. I started with installing the wing servos and ran into a problem. The servo mounts were glued in in such a manner that the aileron servo arm was past the opening (photo 2). This was fixed by cutting back the mount to move the servo into the opening. Then 1/4 inch plywood was epoxied under the mount and into the slot between the mounts. Now the servo arm sits within the opening.

I'm using the sBus system on the Powerbox Royal and the cables have a MPX connector on each end. The wing cables were installed in the root rib of the and fuse using MPX cable holders. At the field when the wing installed, the cables plug together automatically.
I couldn't get my fingers and servos and wood to mount the servos in the horizontal stabs so I elected to install the elevator servos on the fuse side. I did the same for the rudder servo.

The sBus servo wires and air lines are installed. I used the BVM air quick disconnects where the front and rear fuse join. The white quick disconnects are used so I can remove the equipment tray without having to cut air lines. A tray was made and glued to the air intake for the ECU.

I'm not sure what the wind screen was glued in with but it easily popped out when it was touched. This actually made It easier to paint. The canopy and wind screen were paint with Alclad chrome for lexan. The chrome is painted on the inside of the canopy and is backed with a water based black.

Behzad, If I was the worrying kind, I can think of a lot more things to worry about than how easy it would be to clean the inside of a fuselage painted with textured paint

I purchased a vinyl cutter/plotter and decided to cut some paint masks and change the Viper's scheme a little to support my favorite football team. All painting is complete. The horizontal fin/rudder and forward section of the fuse have been clear coated. The rear section of the fuse and wings will be clear coated next weekend.

The Viper has been clear coated with 2K clear. After the clear dried for a couple of days on the rear fuse, I wet sanded it with 800 grit, 1200 grit, and 2000 grit. Then I machine buffed it with 3M Perfect-It rubbing compound, swirl remover, and polish.
All of those hours spent sanding really paid off. The finish came out looking like a mirror. The first two photos are under fluorescent lights. The rest were taken outside on a cloudy, rainy day. You can even see the reflection of the clouds.

KIrk, do yourself a favor a reinforce the fuse below the cockpit arch.. seen one of the latest vipers and it was too weak for simply taking up the plane with two persons holding the nose and the tail. It simply bends and break.

Yes, it came... but somehow the lateral sides even with the CF is very flimsy, specially compared with the first ones, like mine from a few years ago. The pic didnt show them because the fuse was painted inside for the looks.
Our fix here was adding 4 aditional CF strips lengthwise in the fuse corners.. a extra bulkhead would be nice too, but we skipped that for now. Mine has also a few roving laces of CF just ahead the windscreen as the fuse there is also soft.
p.s a drawing may help, and it also show the cabin reinforcement.

I wasn't happy with the way the Viper was turning out. Although is was shinning like a mirror, the scheme just didn't seem to flow very well.
So, I had the got the codes for the Seahawks colors and had some paint mixed and I went back to the drawing board.
First, I created and cut out all of the marking going on the plane. I decided to do the number 12 going on tail with the "feathers" just like the number on the jerseys. It was a lot of "fun" weeding out the unwanted sections of the mask. It turned out nicely and I got the effect I was looking for.

The fuse has been painted with the new colors and scheme with the exception of the canopy frame and the intake lips. The canopy frame and intake lips as well as the wings and horizontal stabs will be painted this weekend.
