Cockpit sheeting completed, I began soldering the landing gear pieces together. I have to solder washers on the inside of the axels and then make up my push rods. After that the airplane will be ready for a final sanding.

The new kits come with 1/64" plywood die-cut for sheeting the cockpit. My older kit provides some rather thick balsa for this task. I like the the plywood idea and feel fortunate to have a relatively large sheet of 1/64" handy.

Next up, the forward cockpit.

The Balsa USA website says the Taube should weigh in at 5 Lbs. and I confess being skeptical, but so far I'm at 3.3 Lbs. That weight includes the engine, landing gear, wheels, radio and airborne battery plus all the built up parts. The only stuff missing is push rods, control horns, sheeting on the bottom of the fuselage and the "cowling" plus the covering. The plans call for 1/8" sheeting but I'll use 1/16" along the bottom and 3/32" up by the engine.

Rather than taking the Mini Telemaster out for a romp in the snow I opted to stay in and keep plugging away on the Tuabe. Next, I'll sheet the bottom, opting for 1/16" rather than 1/8" from the landing gear back, and then tackle the cockpit sheeting. I guess I'd better look at placing that order with Sig for dope and Koverall in the near future.

Those bits at the end were two big triangular balsa blocks! Rather than planing them I use my little table saw to cut them about in half and then sand them. Yes, they were THAT big.

The fin has three one and one-quarter inch holes cut with my drill press and a slight warp. What can one expect after 30+ years? I expect it will come out with a little encouragement when I cover it. Onward...

My wife gave me a 1/6 scale Sopwith Pup for Christmas this year. Upon opening the box I found the note pictured here. Well played, Balsa USA.

The engine and fuel tank are mounted for the Taube. Now I'll start the radio installation, working from the throttle backward. The shape of the Taube's fuselage makes it difficult to get straight. I can see that I'll need to take special care lining up the horizontal and vertical stabilizers during the final assembly.

The Taube's fuselage is a trapazoid rather than a standard square when looked at from the front. It is also tapered at both ends when looked at from above, rather than being a rectangle with a tapered tailpiece glued on like many airplanes. Consequently my building triangles won't help me keep it straight.

The revised plans say to join the fuselage upside down, which seemed like a fine idea until I tried to place former F4 in and realized it was too big to be placed in the fuselage when it is upside down. Sure, enough this looks like something BUSA changed when they revised the kit. The picture in the revised plans shows an F4 former that is about half as tall as mine without the rounded top that mine has. Interestingly the guide to the cut parts on the first pages of the revised instructions show a tall F4 with the rounded top like the one I have. Oh, well.

One idea is to cut the top off F4 and follow the revised instructions before gluing the F4 top back in place after the two sides are joined. The only problem is that there is a center section cut out of my F4 that is so large my F4 will become a U shape rather than a rectangle when the top if cut off, and I'm worried it won't have the strength and rigidity I'd like if I do this. So after sanding the upper and lower longerons and stabilizer supports on the two fuselage sides to an angle that allows them to meet, but still accommodate a 1/4" stick for the rudder post, I have decided to simply join the...Continue Reading
