LOL All-Star Biplane for .020

Post  happydad on Sat Jul 04, 2020 10:39 pm

I am starting a build of a Ace All-Star Biplane. I shrunk the plans on my laser printer 78% then 78% again. It looks like the main wing will be about 22 to 24inches. I will be using 1/16in. balsa where necessary, but using 1/32 in. balsa where possible to save weight. I will be making notes as I go along.
My first picture will be of my wing building area and a rib template half made that was inspired by Ron Cribbs.

Hello! I see that you have had your project !! ... Congratulations !! ... according to your question about MP I was inclined to make it 440mm and 420mm respectively for Cox .020, but I see you have opted for a larger size! .... I'm glad you're on your way, follow their progress and I wish you the best of luck in this beautiful project!

7-8-2020 Some update to the All Star Biplane Build. It has been a busy week, but I have built most of the rib templates. Ribs 6 and 7 involve the wings struts between upper and lower wings and I haven't decided exactly how I am going to attach the 2 wings.

LOL more wing progress

Post  happydad on Fri Jul 10, 2020 9:18 pm

7-10-2020.  more progress on the wing. i'm having a lot of trouble with the $ store super glue. It used to dry very fast, but now takes forever to set.

All-Star Biplane for .020 Img_0517
still need to decide how to install ribs that attach to cabanes to fuselage. top wing ribs 6 and 7 not flat on bottom. bottom wing ribs 6 and 7 not contoured on top. also need to install upper and lower spars.

i've been toying with the exhaust port twin slits and taking out the bar. fun. see porting posts.

Post  happydad on Mon Jul 13, 2020 2:06 am

7-12-2020. some progress on the BiPlane. I still need help with the UPPER Wing Cradle.
7-14-2020 UPDATE:SEE PHOTO BELOW

Does anyone have an All Star BiPlane or know what the highlighted area on photo means ?

I have assembled my version of the forward hatch which holds the assembly with supports the Upper Wing assembly, (Cabanes), but the drawing shows a 1/16 flexible wire attached to the cabanas and wound with string.
   My question is: Do both inside Cabanes have the soft wire and what supports the wing? why not use a piece of 1/32inch thick, on my .020 version, plywood attached between the cabanas? Mark showed a picture of the all star biplane he has,  but I can't tell how the wing is attached.
Anyone?     Head Bang  Head Bang  Head Bang  Head Bang  Head Bang  Head Bang  Head Bang

see note. on top is my version of the forward hatch

that's all for now.  happydad RC Plane United States Old Bugger Shocked Shocked Shocked


>>>>update here:
Dummy me, I figured it out while answering a post. The drawing above shows a 1/2 section of the top view of the fuselage and the top wing, but doesn't say so. I am adding the original drawing with a correction showing my interpretation of the top wing to cabanas connections. NOW it is obvious. I was re-reading the suggestions to outerzone and RCG, which showed pictures hard to visualize, when I thought what if that shadow is that 1/16 wire they are talking about, but not here with the picture??   see for yourself.

Thanks for the links. I like Mauricio’s idea of holding the wing, but I want to be able the remove the wing for portability.
Still have to read the RCU article.

Hi happydad, It's nice to see that you're building a model! It's also a treat for me; that it's a bipe! Multi-winged aircraft are just classic IMHO.

I have the Ace kit. I bought it from Tower Hobbies back in the 1990's. I knew I'd want to build it someday.

Looking very much forward to seeing your scaled-down version! Very Happy Popcorn

Thanks roddie: I am still having trouble finding time to work on it.
    What size is yours, 34inch or 72inch. I retraced my steps and found out I started with the 34inch wingspan version from outerzone. I was trying to explain to iceberg how to download the tiled pages, so it can be printed on 8 1/2 x 11 paper and taped together, and suddenly realized the numbers didn’t work because I was starting with the 72inch version.
     Outerzone offers a full sized 72inch wingspan drawing that fits on 8 1/2 x 11 paper, kinda hard to read, but it’s all there. And also offer the 34inch wingspan in tiled version where a full sized sheet for the 34inch wingspan is printed on 8 1/2 x 11 sheets and taped together.
     Or as I did reduced each 8 1/2 x 11 page by a percentage, in my case 78%, because my laser printer only reduced in steps, 94%, 86%, 78%, and and something in the 60% range. So I took the two pages that made up the wing and measured the wingspan after the pages had been reduced by each percentage, for instance 78% = 13inch x2 = 26inch wingspan. I tried other combos and wrote down the wingspan for each. Then I took each percentage and reduced that page by each of the choices, 94, 86, 78, and wrote down those numbers. Reducing by 78% then 78% again can out close to the 22inch wingspan I wanted ideally, but after talking to forum members, especially Mauricio, I decided to reduce again by 94% more and ended up with about 20inch wingspan for the upper wing, and 19inch for the lower wing.
>>>>>>>>Edit 7-16-2020 7p.m.PST
Hijack my own build instructions
   I was awake all night Tuesday night. Wednesday was the last day of helping seniors with taxes and some5hing else was bothering me. I was explaining to iceberg in a PM and sort of above how to make the 34inch wingspan drawing for a smaller wingspan. My copier-laser printer has fixed copy reduction setting as explained, but what if I could reduce the original print of the .pdf file where 100% was 34inch wingspan. So 20inch wingspan, my goal, was 20 / 34 = .58 or 58%, don’t have my calculator, just pretend, LOL. So why not print the original.pdf file at 58%. Bingo, so I tried it. I printed the 3 pages that had the wing(s) on them. Surprise #1 the picture did not fill the entire page.  Huh... , DUH. 58% of 100% is not a full page. Surprise #2, after cutting and pasting the 3 pieces together and measuring 1/2 chord, if was 10inches. 2 x 10 = 20inches. DUH. Why print 28 pages, reduce by 78% 28 pages, then reduce those 28 pages by 78% the those 28 pages by 94%. Lot of wasted paper. I actually only printed the 2 wing pages then when I was close the 3 wing pages, 1 part of the wing was only about 1inch. Lot of wasted time. I was trying to save iceberg a lot of time and paper as he is isolated in Canada for a short time and wanted to get started NOW.
O.k.  Hijack over. <<<<<<<<< thanks for listening

So hurry up with your build so I can see how to put together the front hatch and the cabana which support the upper wing. The drawing shows a 1/16 piece of soft wire, as shown in posts above, attached to the cabanes, but I can’t see the wire in the other view(s).
  It just hit me that maybe what I am supposed to see in the top view of the fuselage with wing cutout above is 1/2 of a U on it’s right side, the each of the legs is attached the the
cabanes with string.  Jaw Drop  
    WOW. That simple? I wonder why they didn’t show it that way, or say “1/2 section of wing area showing connection of wire to cabanes”, DUH!

That’s all for now. Hope to see your build soon. How many cox .049’s do you think it will to take for liftoff?  Airplane Hijacked

Wow, beautiful plane.

Can you send a pic of the top wing saddle? Is it 1/16 wire wound with whatever they called the string, or is it reinforced. In fact with a O.S. .15 for an engine did you double or reinforce the inside cabanes? And why no struts on the outside of the wings joining them. Wing flutter?  I would hate to see my top wing go flying off if I did a loop or axial roll.

Great picture and nice colors. I will have to go with more cloud contrast colors as my sight is not to good these days.
Thanks again for the feedback, even if the engine is an O.S. LOL couldn’t you at least used a Cox Tee Dee  .15. Again, LOL, but this is the COXENGINEFORUM I Love This Forum!

Yes, I have flown it, and it does a great job of ripping up the sky! I was really quite surprised by its ability to perform decent rolls, as it has NO AILERONS- just rudder, elevator and throttle.

I will try to get a picture and description of the structure you are curious about.
Thanks for the compliments of the biplane. It is covered with white Ultracote and translucent purple Monokote.

My kit is the smaller version (as Doug's-Gus's is)

All-Star Biplane for .020 Ace_al10
All-Star Biplane for .020 Ace_al11

I bought an OS Max .10FP/RC in the same order from Tower sometime back in the mid 1990's. The kit is complete (unbuilt) and the engine is still NIB.. including a remote needle-valve mount that OS was offering at the time.

All-Star Biplane for .020 Os_10_10

Here's an interesting story about a 34" Ace All-Star Biplane. One of the more animated RC pilots belonging to an RC flying-club local to me had one that he was bored with. So.. he modified the nose to fit a .40 (2-stoke) and re-balanced the air-frame. I was there at the field for the maiden. He was a skilled pilot.. and wrung the little bipe out, until finally... the top wing folded when pulling out of a loop.. following a Lomcevak maneuver.

I haven't much experience with scaling/tile-printing. I'm always fascinated when the topic comes up though. I'm hoping to build more models from plans when and if I reach retirement age. I've been stockpiling wood.. in anticipation of that.

I like the whole idea of scaling down model aircraft. The CEF 1/2-A C/L Profi-Scale Speed Contests were a lot of fun for me. The designing and building were extremely satisfying.. along with seeing what other fellow CEF'ers were coming up with for models.

Sending some positive energy your way! Thumbs Up

7-26-2020 - Progress finally. I have busy with home related things. Wifes BIG birthday is this coming Tuesday.

020 All Star BiPlane progress has been really slow, too many broken things at home to count. But finally some progress on making more parts. I cutout and shaped both sides of the fuselage and an extra for a pattern. I cutout and shaped the stabilizer and elevator halves and an extra for a pattern  and setup a flat board for building the fuselage.
