I have always liked the looks of the Albatross D3. last summer i picked up the Dancing Wing D3 kit from Great hobbies.  online pictures show fuse at lower wing isn't flat and landing gear rear attachment point was that of the D5. these should be easy fixes.

The 'instruction manual' is pictures with some part numbers on it. you need to refer to plans and the pics to build.

online pics show there is a gap between the bottom wing and fuse bottom due to the rounded fuse. this should have a faring to blend.
Assembled the front fuse so that i can start the changes for the wing and the fuse side panel at the lower wing.

Next the bottom wing build was started so i can see how to build the modifications.
At this point I noticed the bottom wing was wrong for the D3, it was a D5 lower wing. Since the fuse was wrong at the wing joining, I stopped and pulled out the rear formers. Sure enough. they are oval and not flat sided. the D3 kit is actually a D5 

with the bottom wing done far enough, the rear fuselage was added.

Always loved the albatross Marc. Think this is going to be nice...

Started to assembled the hatch and this holds the engine. I didn't want to use the kit supplied so this meant i needed to hold off sheeting the hatch so I can see how to mount a 3d printed one. I got a BMW iii engine file online. Had to experiment to get a size that looks about right. the file isn't of the BMW 3a but another variant. To me, looks like an early Austrian version.

filament printers are not great for getting smooth details, resin printer would have been better.

Added spark plug wires, the front cap for the camshaft and 90deg elbows for the cooling pipes (to be fitted later).

the rocker valves and springs didn't print well at all. Cut those off and designed, printed new rocker arms, spring cap and made the springs from green Floral Wire that was wrapped around a pipe, then painted to look like metal again.
painted and weathered a bit using aluminium, and tan dye.

The printed exhaust won't work. As some BMWs used straight pipes, i am thinking of making some of those instead of the large flowing exhaust common to the bmw.
Still thinking on this.

Controls use steel cables direct to servo. I didn't want this load on the servos so made tiller arms for the elevator and rudder.
Elevator I used some nesting CF tubes, added some silicone lubrication to reduce any wear.
The Rudder I ended up making a servo box on my 3d printer with a tiller post. Used an oversized servo arm. Drilled out the center for a bearing. smooth movement.
Then realized that if i sheet the fuse I won't be able to run the control cables. I don't think the outlet tubes would allow for a pull wire, cable taped together to pass through. That meant finishing the tail section where the steel cables come out. this was sheeted and sealed.
Can now get back to sheeting the rest of the fulelage.

last 3 photos modified, can't modify the older posts... will start making them smaller.

started sheeting the fuse. still lots to go, then sanding. will post more when body is done.

sheeted the fuselage. kit has pre-shaped panels to sheet body. fit is pretty good but in hindsight, think I should have split the sheets into thinner strips to give a more rounded look and less sanding to shape. Still needs lots of sanding but will do outside when temps allow.
moved onto the tail. the rudder fin was an open structure like the rudder, however, the real had the fin sheeted, so I added some.
assembled to see the fit. pretty good fit.
