What are you ordering:
You are ordering a print from the main PDF file in this listing
, it´s exactly like taking this file in a thumb drive to a local print shop and ask them to make a print.
About the plan source:
You should verify if the source file has the quality for the type of construction you intend to do
, we will print the file without any kind of enhancement or scaling
To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer
and set the view level or zoom level to 100% or 1:1 or
full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool
make sure all the parts fit together and have the correct size.
In doubt please ask us
for an opinion.
We can scale this plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.

About our printers:
We use professional quality laser OCÉ and Canon printers/copiers
, these printers use toner
, not ink so the printings will be durable and waterproof
About the different media types:
White Bond paper, 80 grams per square meter.
Bond Tracing paper:
Bond Tracing paper, 90 grams per square meter.
High quality polyester sheet incredibly durable, will resist cuts and glue and can be washed (I use it as sail material on my RC sailboats).
We charge by print length (914mm or 91,4cm or 36in. by the length of the print)
This means that a plan 120cm by 150cm will be charged two times 150cm because it will be printed in two tiles, a plan 91cm by 150cm will be charged one time its length or 150cm and a plan 91cm by 40cm will be charged 40cm.
The system will try to fit a plan in the 91,4cm of the printer width in order to reduce the costs or print length to the maximum. This is the same charging method used in any printshop.
We will use paper or waxed paper padded envelopes for folded plans and hard cardboard tubes with plastic ends for rolled plans, depending on your choice.
We ship from Portugal, Europe and use the reliable Portuguese mail system CTT.
CTT has delivery agreements with different entities on each country so if you´re from the US you may have your order delivered by USPS, in the UK may be Royal Mail and so on.

3D Printed Parts
Order 3D Printed Parts for the ET-20 Bob Martin 50in
3D printing allow us to design not only complete airplane models but also parts to complete balsa, foam or even composite model airplanes.
Parts can be designed and printed to fit exactly a model you have or a model you plan to build, even if you are not building this model to the full size plan.
3D Printing, and 3D CAD allow us to create the actual parts to fit on our models but also allow us to create negative molds where we can make composite parts.
I´m adding this service to all the plan listings on the site knowing that not every part you imagine or need can be done, knowing this, jobs will be evaluated case by case and a price estimate will be given on request.
What can be done with 3D Printing:
- Wheel Pants
- Landing Gears
- Wing Ribs
- Motor Mounts
- Servo Trays
- Servo Covers
- Complete Models
Full Models, Wings or Fuselages
It is possible to design a complete model for you but keep in mind that this is a lengthy process, many hours are needed to design and test a fully 3D Printed model. The finished model cannot have the same internal structure of the wooden made counterpart because it wouldn´t be possible to print it, it would have to have a structure like the models you can see in the 3D Printed Kits section of the site.
From the outside they are very loyal to the plan but still they have to be printed in sections, typically to fit a 250X210X200 mm cube that is the printer maximum build volume.
3D Printed planes are also heavier than light balsa models, all built up and ready to fly, with an electric power system they are generally a little lighter than the same model if it were powered by a glow engine. Please have a look at the 3D Printed kits section to have an idea on this.
I will calculate a price upon request, please contact me here mentioning this PlanID: 92318 and the job you wish me to do.
