This gentleman had given us estimates on tree work at work. We called him and he said, I’ve never had a request like this before, but he agreed to try.

Two utility trucks came by while I was waiting for him and both tried to reach it with cherry pickers but could not get close enough.

Goal: repair it and fly again before the end of summer.

A ‘lofty’ goal. Ha, ha, ha.

The good news is that the Taube had a successful maiden flight. The bad news is that the Kadet was NOT in front of that tree on final approach. The ugly part is that it remained in that tree through very heavy rains.

The silver lining to all those rain clouds is that I had an opportunity to model some grown up behavior for my son. No four letter words or displays of anger. Find the humor in it and take away the lessons about depth perception, humility, and gratitude because no one was hurt. Notify the club and approach the property owner who turned out to be a gem of human being and said, "I'm cutting down that tree later this season anyway, do whatever you want to do." He also modeled good behavior for my son.

Next steps...

Six months from start to finish; a Balsa USA Taube 40 completed with Sig Koverall and Brodak dope, and powered by a new OS 35.

Now if the wind would calm down...

I ran out of white paint for the squares on the Taube’s wings and had to stop short of finishing it this weekend. Still, the major painting is finished and I manged to run a tank of fuel through the engine.

The wing needs a sanding and another coat of paint, but the radio and engine are installed and the fuselage is just about finished.

Brodak calls this color Cream Dallas, but I think it is closer to Wiffle Bat Yellow. Oh, well. The price was right.

Covering is underway with Sig Koverall, a glue stick, and Mod Podge. So far, I’ve completed the tail feathers and fuselage. Next I’ll tackle the wing and cockpits. If the weather guessers are correct, I may get a chance to apply one or two coats of thinned nitrate dope to it this week.

This dashing fellow started life as a Williams Bothers race pilot, but he’s decided to pilot my Taube instead.

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

It is common for me to spend 30 minutes or so with the Dremel tool making holes and removing weight from the backside of the LE or underside of a top spar to balance a wing, but this time is unique. I've removed all the weight I feel comfortable removing from the left side of the Taube wing, but it remains a full quarter of an ounce heavier than the right side. Looked at differently, it balances about half an inch to the left of center. I'll either have to live with it or (shudder) add that quarter ounce to the right wingtip.

I stumbled on these pictures in an old photo album. They show a rocket glider I built in middle school sitting on the launch pad plus a shot of it taking off. I put a few flights on it and then hung it from my bedroom ceiling. I recall using a plastic nose cone to taper the back and placing the bottom of that nose cone at the front. I used plastic straws for launch lugs and launched it at an modest angle. It flew on a mini A motor, climbed out at a shallow angle, and then found its wings in time to glide back at a surprisingly gentle speed. The canopy and pilot were from a 1/48 scale Testors plastic model kit of the F-19 Stealth fighter.

The good news is that the two sides of the wing line up well. I've completed the preliminary work with the plane and sanding bar along the LE corners and I have joined the two sides. The original instructions call for raising one wing 1 1/4" at the first tip rib while the revised plans call for raising it the same height about three inches inboard at the double rib - effectively increasing the amount of dihedral . I followed the revised plan.

Next is the three part center rib and dihedral braces.

The parts for the left side of the wing have been cut out and made ready assembly. No word from BUSA yet but I'm feeling better about the results on the right side. I haven't run across any online pictures of Taube bones that look substantially different than mine. I figure that means I'm on the right track.

I've completed the right side of the wing, but I'm a little unsure about the blending to be done at the LE corner. Rather than make a guess about it I've written to BUSA for some guidance before I begin building the left wing.
