Supra-Fly 25 model airplane plan

Supra-Fly 25

OK Model Co. Ltd's Supra-Fly 25

The Supra-Fly 25 is designed for sport aerobatics and has an impeccable pedigree: its part of
the Supra-Fly design series by Hanno Prettner, many time World Champion in r/c aerobatics.
This version spans 48 inches and can be powered by .20-.35 2C or .40-.45 4C engines, and the plans show the details for either a tricycle or "taildragger" landing gear. The wing has a slight taper and this reviewer notes that the plan depicts the root rib only; modelers will need to generate the tapered ribs using standard techniques. The Supra-Fly series was produced as Almost-Ready-to-Fly back in the
80s by OK Models.

About the Plans Printing Service.

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.

Plans Scaling:

We can scale the Supra-Fly 25 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.
To order a scaled plan please copy the plan url or ID and send us a message with the desired wingspan an any other info you may find useful.

You will receive:

  • Laser Printed plan on good quality paper or/and Tracing Paper and/or Polyester sheet, depending on what you have purchased.
  • Rolled sheets, up to 5 or 6 in the same cardboard tube.
  • Envelope, up to 3 or 4 sheets per envelope.
  • Articles and Instructions if we have them for the given plan.
  • Air Mail, economic and reliable.

About our printers:

We use professional quality laser OCÉ printers/copiers, these printers use toner, not ink so the printings will be durable and water proof.

About the different media types:

Plain Paper: Common white paper, 80 grams per square meter.
Tracing paper: Common Tracing paper, 90 grams per square meter.
Polyester: 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 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.
Orders are dispatched on the next or second business day after purchase.


We charge according to the ctt.pt postage table.


When I order something online I like to know where my stuff is so I strongly advise you to track your order. Even if you don't pay for the tracking option, for orders above 35 Euros or so I will offer you this option.


Orders can be paid with Paypal or Credit Card via Paypal and are shipped to the address on your Paypal account or to the address you set at checkout.

About the Calculator:

The Plans Price Calculator will read the plan file and output all the information on the panel to the right according to the selected options, you can change the options and request a new quote at any time.
If you would like to print a plan that is not on the website you can upload it to the main plans category in pdf format, multiple sheets in the same pdf file, and use the Plans Price Calculator to get a quote and place the order.
