Balsa USA Taube 90 Build Thread

I hope I've made this comment before the build is too far along. Given that this is a BUSA kit and I believe that there being two sheets for the wing plans was mentioned, I would suggest making certain that the plans for the wings match one another. I don't remember if it was an issue with the Bristol Monoplane (also with laminated wingtips) but there were side to side differences on the plans for my N-17. Aside from that I've built three BUSA kits through the years and they have all been good flyers.

Thanks, mgnostic. I will check. It appears that in order to make the second (i.e., left) wing sheet, they just flipped the original right-wing sheet upside down to make a left wing plan. All the writing is in reverse. Oddly enough, I do remember a few notes on the left wing plan that were printed correctly (i.e., right-side up) but I will have to look the plan over once I get to that stage.
The weekend was busy with a Club swap meet on Saturday and then I made the bonehead mistake of going to a Major train show on Sunday - for those of you in the Northeast, it was a the Eastern States Exposition in West Springfield and it took up four of their buildings. That really got me distracted as I decided to make an 'inventory' of some old but never-used HO stuff that I'd gathered or inherited over the years.
Fear not, I'll get back to the Taube shortly but I do have to scratch this itch. I wanted to do a little bit of a job and see if I could get the engines running. I'm not going to re-direct this thread into railroads, don't worry.

A little late to the party but glad to be here! This looks like a really interesting build and I'm really looking forward to seeing this one at the field! Is that big one-piece wing going to be tricky to transport? What are your plans for power?
(Oops, missed your earlier post Bob where you talked about engine choices. Glad it's going to be a 4-stroke!)

Hi everyone, Surprised to see me????
It's been 14 months since I last touched the Taube and I apologize to anyone that I let down by dropping the build.
I'm getting back into the build now and have to correct a few things. The wingtip has taken some effort and there is one issue that I have to correct (more to follow) because I am not sure if the kit is wrong or if I am. The past year+ has been taken up with Club activities, repairing other planes, doing odd RC modeling jobs, etc. The wing has been on the bench for all that time and one thing that I had to correct was to exile one of the cats... he decided to take a nap on some of the framework and that had to be repaired. I wanted to 'repair' the cat too, but my wife put her foot down. That means that I was outvoted 2-1.
If you are building this kit, II will reiterate what was said earlier about being careful NOT to glue anything into place until the instructions specifically tell you to do so. If they tell you to 'place' something, then just place it.

I used a couple of things to help hold the laminated wingtip together. The first thing that I did was to use a dab of hot melt to hold the LE former to a couple of ribs to keep it from slipping around. Here's the trick. Turn on the gun and after the glue starts to melt and drop out of the tip, put a little on a nail head and wipe that on in 2-3 places to keep things aligned. The photo shows how little is needed. Don't glue it from the gun itself, that's way too much glue... I'll be able to pick this little bit of hot-melt off later if I feel like it.
The laminated wingtip also slipped around, so I made up some clamps out of 3/4" x 3/16" stock that was trimmed off from some of my old woodworking projects. I tried to use a tiny squeeze clamp, but this didn't work. The leverage from the arm of the squeeze-clamp made the LE lean over. With the homemade clamps (the whole job took 10 minutes) there was no leaning or tilting of the laminated LE.

I want to finish the wings so that I can start on the Fuse. I get a kick out of re-reading Dick Pettit's review where he describes the tail feathers as resembling a Rose Trellis.... The elevator appears to be a bit on the small side according to the plans, so I might enlarge it... but I am getting ahead of myself... WIngs first.!!
The first wing is taking 14 months... The next one will probably only take 14 minutes after what I've learned...

N1EDM, don't feel bad. I have a build thread on RCG for a PT-60 that's been going since September, 2016, and it's still not covered.
And now I'm starting another build for a Top Flite Elder 40.
FlyerInOKC, how does one go about joining your Builders Slower Than a Dead Turtle Nailed to a Fence Post Association?

Just a few notes to keep this build-thread alive. I have already gotten outlines ready for the next four posts. But for now, I would like to say from 'lessons learned' to date:·
As noted earlier in this blog, this is not a beginners kit – but neither is it especially difficult if you follow the directions explicitly. You need a couple of easier kits under your belt first so that you are familiar with fitting and working with balsa and softwood materials. The wing is going together very well now.·
If the instructions say to ‘fit’ something in place, then just fit it. Do not glue anything into place until the directions specifically tell you to do so. Do not over-think the process. Ask me how I know. Or, better yet, please don't ask and save me the embarrassment.·
The directions are good, but the photos could be clearer.·
Anything done after 9:30PM will take you twice as long to undo the next day.·
The kit has very nice die cutting but still needs minor sanding to shape, as do most kits·
I cannot find Cut Rite waxed paper any more..... But when necessary, I have been using backing from Monokote under glue joints. Save that backing from your next covering job - even the small pieces. CA does not stick to it.

Thanks, Rammone3, I've tried that. To be honest, I think that they've changed the formulation anyway. Does your house-brand waxed paper really protect against CA???
For the record, I also use the Parchment Paper but CA sticks to that too. The only thing that I've found that works against CA is the Monokote backing. Hmmmm, I wonder if anyone has used Ultracote backing and whether that works or not???
Comments anyone???
And, if you reference up to Post 71 again and that comment about 9:30PM.... well, I'm proof that that's the truth. I went and partially glued in a stringer last night. This morning I found out that it still needed more work on it that would have only taken 15 seconds instead of 15 minutes if I had not glued the *&^$@#&% thing in place too early

Thanks, Flyer. I never knew that about the reformulated waxed paper. So, it's no good for us anymore - at least for CA. I have also heard rumors that Plans Protector is nothing more than the backing off the rolls of Monokote. I don't know if that is true or not, but I've been using the old Monokote backing with good success. Thanks for confirming that Ultracote backing also works. I've never tried that book protector stuff. Where do you get that??? An office supply store??? Wal-mart?
