I'm following both JTEC threads, Doc Evil's and this one; very interesting. Did you make your own vacuum bag or buy it? Is it required or can you go old school and use weights to hold the wing tight in the molds?

I'm using the ez vac from ACP.
You don't have to bag, the old fasion way of stacking weights works too.

The bag is nice because it pulls the parts together in all directions,

Here are a few pictures of the rudder. I did not bag the rudder, just used weights to hold it while the glue dried.
After attaching the leading and trailing edges and a little sanding I laid out the cut for the hinge lines.

It's time to get back to the build. In between various family and friends visiting for Christmas I was able to sneak out to the work shop and get a few things done.

I mounted the engine so I could mark the firewall for the fuel tube and throttle linkage. This is the third plane I have build with the intentions of installing a DA200. I stacked 2 inches of spacers behind my DA150 too get the spacing correct. If I do score a DA200 the plane will be ready.

I mounted the servo behind the firewall and will run a pushrod out to the carburetor.
At the tail I added a couple of 1/4 inch spruce wood parts to give the rudder a little something to stick to. A 3/8 block glues to the tail and then the rudder hinge line.

I sheeted the bottom and cut out the landing gear pad area and sanded to fit.

Here is the trick I picked up from my buddy Earle Andrews , but he doesn’t know he helped me figure a good way to do the rudder cutout.

I work with the vertical stab and turtle deck together. First temporarily set the turtle deck beside the vertical fin and make a mark on the leading edge and trailing edge of the fin. Next wrap some plumbers solder around the fin to get the shape that needs to be cut. This is the method earl uses for spinner cutouts, but works great for the turtle deck too. Now just cut the shape with a saw leaving a little room to sand to a good fit. Work slow until the fin fits in the turtle deck.

Instructions? Maybe I should have read them first. It probably would have said to glue the vertical fin in place before the turtle deck. It works better that way, ask me how I know.

Jerry, what did you use on the balsa sheeting to make it bend around the frame so nicely?

BTW, great idea with the solder thing! I've used the same method for cutting up and measuring header tubes.

Bill- I used a spray bottle to mist water over the balsa so it bends easy.

I understand Kent. You've got to work when you can.

It don't look like I got a lot done today, but I worked my tail off on the tail.

Lots of sanding today. I glued the vertical fin in place and fit the rudder. I took my time and got the hinge line nice and straight.
