1/144 Scale Luscombe 8A Silvaire by R&R Modelers
Posted by Rdutnell on Thursday, March 6, 2014 8:13 PM

Hi Everybody!

My name is Russ and let me start by saying that R&R Modelers is not a company; rather it is a friendship and collaboration between two modelers to make realistic small scale aircraft models.  I “met” Ron through this very Finescale Modeler Forum, when he posted a response to a WIP I maintained on “A Career in Flight” display I made for my dad for Christmas. http://cs.finescale.com/fsm/modeling_subjects/f/2/t/157366.aspx

The display features 1/350 scale models of the planes my dad flew during his career in the USAF.  I designed the models in AutoCad using plans (of varying quality) and had the models 3-D printed by Click2Detail (C2D).  The images below show the display, first, as the concept I designed in AutoCad, then the final display that I gave to dad.

 

Ron, and a couple of others, asked if there was a possibility of buying one of the models.  As fate would have it, C2D recently started a service in which designers can upload their CAD models and they print them, sell them and ship them and the designer gets a percentage of the sale.  All of the models in the display are available at:

https://click2detail.com/browse_products.php?total=146&incrementBy=9&id=&pagename_session=browse_products.php&id=&startIndex=27

I have really gotten into designing models in this fashion, and Ron has provided many candidates for what aircraft to make.  Being a pilot, he is also more knowledgeable about aircraft than I am and has offered numerous suggestions on how to improve the designs.  In addition to the 1/350 scale planes in dad’s display, I have also designed the following models, all of which are available through C2D:

1/350 scale models

Cessna U-3A Blue Canoe (Cessna 310B) - Landing gear down

North American FJ-4 Fury - 2 versions (landing gear up and landing gear down)

Luscombe 8A Silvaire

Luscombe 8E Silvaire

Spartan 7W Executive

North American FJ-4B Fury Deluxe Version

FJ-4B Armament Kit

EKTRO AP8850 SDA Aircraft Tow Tractor

USS Greenling - SSN-614

 

Ron has acquired several of the models, one being the 1/144 scale Luscombe 8A Silvaire, that I designed on his suggestion.  The Luscombe 8 is a high wing, side-by-side seating, conventional geared monoplanes designed in 1937 and built by Luscombe Aircraft. Approximately 4,500 were sold and production continues to this day, although the aircraft has undergone numerous modifications. 

To design the model, I started by importing plans downloaded from the internet into AutoCad and scaling them appropriately.  I then traced the section outlines, copied them to the correct location on the center line of what will become the fuselage, rotated them 90 degrees and used the Loft and Extrude Commands to generate a “solid”.  Similar steps were followed to create the wings, stabilizers and landing gear.  The images below show the plans with my tracings before lofting.  Note the magenta objects inside of the red fuselage sections.  These were made to hollow out the interior of the cabin.

 

The images below show the result of lofting and putting all of the parts together as they were drawn on different parts of the plans.  It is important when preparing the various parts to keep good reference lines for moving (or copying) and rotating accurately.

 

 

With the primary airframe completed and a propeller having been copied from a previous model, it was time to start detailing.  To highlight the control surfaces and door I used the Project Geometry Command to project tracings of the outlines onto the surface of the model.  I then extruded and lofted 0.01” diameter circles along these lines and subtracted the resulting cylinders from the model.  In pictures I have seen of Luscombes, some have 4 struts, and some have 2.  I at first was going to do 4, but then decided to go with just 2.

 

Since C2D offers the option to print in clear plastic, I decided to make the windshield, windows and skylight as separate parts.  This required, what I call, dicing and slicing the fuselage to obtain the desired parts, resulting in a model containing 11 parts.

In addition to the strut differences, pictures also show that some Luscombes had covers on the forward landing gear wheels, and some did not.  To provide potential modelers with multiple options, I decided to include both sets of landing gear and a spinning prop (also pilfered from a previous model), making the final part count for the model 14.  I also drilled a hole in the underside of the fuselage for those who may wish to display the model in-flight like I did on dad’s display.  The final  step in making the CAD model was to put the smaller pieces on frets for better durability and ease of handling, as seen in the image below.  The parts in cayan were printed in clear plastic.

 

 

With the CAD model completed, I uploaded it to C2D, having created what I told Ron I consider to be the canvas for people like him to create their remarkable works of art.  If you haven’t seen Ron’s models, you are in for a treat, because he really is a master.  Although it is true, that I make 20% on every model sold, I am not in it for the money, in fact I may have made myself an indentured servant, as I am spending more to have models printed for myself than I am making on them.  Rather, I do it because I found that I really enjoy making them, and if others benefit, it’s win-win.  And as you will see the reward comes from seeing the masterpieces that people like Ron can turn my canvas into.

On another note, I have a cunning plan (man, I need to see if I can find the Old Black Adders on DVD) for a display I am going to make for myself using the 1/350 scale models I make.  I have a 8” x 4’ shelf that needs to be filled and I was thinking I could make like a puzzle of various scenes.  The image below shows an initial concept.  In front of the hangar is an F-111A and F5A (in progress).  On the runway is the F-111TACT taking off on its maiden test flight (which I attended) with two chase T-38’s on point.  On the tarmac is the gear down versions of the U-3A and AC-47.  Look for more on this as it progresses.

Here is a picture of the Luscombe 8 Silvaire if you aren’t familiar with the aircraft.

My name is Ron and wanted to share with everyone my experiences building the Luscombe 8A Silvaire created by Russ and C2D.  

For background, my model building is almost exclusively confined to 1/144 scale and smaller scales.  Since 1998 I have been concentrating on light civilian planes produced by my friends Don and Terry who create wooden mold masters and then cast them in resin.  For some reason I decided to hollow out these solid resin models and then create interiors out of styrene plastic and windows out of clear plastic.  Since purchasing my first solid resin models from Don and Terry I have completed over 40 that now share space in my display cases.

As Russ mentioned in his post, I saw his tribute to his dad and was immediately drawn to the fact that Russ used AutoCAD and 3D printing to design and create the planes he needed.  We discussed model building and AutoCAD/3D printing and before you know it Russ created the Luscombe 8A in 1/144.  

The models come from C2D all cleaned up and ready for assembly.  There is some visible stepping in some areas, however, I found it quite easy to remove with light sanding.  The model is printed in plastic (not sure what type but CA glue is needed) with the windows printed in clear resin.  The quality of 3D printing is very good in my opinion but I admit Russ’s models are my first attempt at working with 3D printed material.

I did not have any warping of parts with my Luscombes.  However, if you do you can remove it using hot water.  I washed the parts (carefully) in warm water with a mild detergent just in case there was any release agent remaining.  Initially I was going to hollow out the interior as I customarily do but I wanted to get the models done quickly so I could report back to Russ as to how things fit and show him photos of the finished models… so I didn’t.  I installed the windows first.  I have to say the fit is perfect and tight so no glue is needed.  Next, I added the left side of the cockpit gluing it into place.  Russ also adds locator pins so the part lined up perfectly and fit together without gaps.  I did use a Squadron Green slurry to lightly fill the line between the main fuselage and the left cockpit piece but I don’t think it’s really that necessary.  The main wing and landing gear were added next using CA to hold them in place.  You need to be very careful removing the small pieces from the frets (sprues) as they break easily or fly across the room much easier than styrene plastic!  For the wing struts I decided to use brass flat stock because I liked the size better than the printed ones.

I covered my model with Chrome foil by Bare-Metal Foil.  I used thin strips of it to help simulate rivet lines.  The foil adheres well to the 3D printed material.  I did use chrome paint on the landing gear, prop spinner and struts because it was easier.  For the paint scheme I used custom made water slide decals.  I added a wire antenna, painted the tires and put the model into the display case.

I really like these models.  The shape appears to be accurate and the fit of everything is quite nice.  I’ve started work on several of Russ’s Cessna 310B’s (U-3A) and have 10 more models on order!

I build a lot of airliners in 1:144, but the Silvaire was not that big of a plane to start with.  I'm afraid in 1:144 it would be dinky.  For light aircraft I usually prefer 1:48. I did build a 1:72 homebuilt bipe- forget the name but it was very much like a Pitts.  That was almost too small!

It is pretty small Ron.  It's 1.67" long to be exact.
