Extra 300

Roger Hardie Industrial Design's Extra 300

The Extra Flugzeugbau EA300 is a two-seat aerobatic monoplane capable of Unlimited category competition. It was designed in 1987 by Walter Extra, an award-winning German aerobatic pilot and built by Extra Flugzeugbau.Design of the Extra 300 was based on the Extra 230, an early 1980s monoplane having a wing made of wood. The Extra 300 has a welded steel tube fuselage covered in aluminum and fabric. The mid-set wing has a carbon fiber composite spar and carbon composite skins.

An alternative to building this Extra 300 from scratch is purchasing the model marketed by several online model airplane websites. The symmetrical airfoil wing and horizontal stabilizer are set at 0° incidence allowing for inverted as well as upright flight. There are only a few specialty parts in this model, those being a fiberglass cowling and wheel pants, and the formed canopy. The landing gear is formed from either 1 mm aluminum or covered piano wire. Other than these few "specialty parts" this model airplane is conventional build with balsa and plywood.

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 Extra 300 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.

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.

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.

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.
