The Auster J/4 first flew in 1946 and was a relatively unpopular, single-engined, two seater built in the UK by Auster Aircraft Limited.

Originally fitted with a 90hp Blackburn Cirrus Minor 1 engine, only 27 J/4 aircraft were built.

The aircraft does make for an excellent rubber-powered model however, with its high wing and lightweight design offering an interesting and unusual alternative to to the Piper Cubs and Cessnas you see everywhere.

This model is a rework of the original Aerographics balsa wood kit of the Auster J/4. We've completely revamped the design, from the instructions to the cut parts, to provide you with a great building experience from start to finish.

Please note: this is not a model for a beginner and requires a fair amount of both patience and skill to complete.

Inside the box you will find all of the materials you will need to create a superbly detailed 23" flying model of the Auster J/4. Although designed for rubber power, the kit includes parts to help you build an electric motor powered, radio controlled version (the motor and electronics are not included!).


  • Laser cut balsa parts
  • Full size CAD drawn plans & comprehensive instruction leaflet
  • Parts guides, colour-scheme plan and registration templates
  • Quality covering tissue (white, black and red tissue for the markings)
  • 25mm plastic wheels
  • Propeller, 3/16" FAI Super Tan rubber motor & hardware
  • Piano wire
  • Aluminium tubing
  • Acetate for windows
  • Aluminium hinges for rubber/free-flight
  • Mylar hinges for RC conversion


Most orders are shipped via Royal Mail’s Tracked 48 service.

For larger or heavier orders, we use UKMail/DHL to deliver your package on a Next Working Day service.

Shipping is free to UK Mainland addresses for orders over £30.00, otherwise we charge £6.00 for Royal Mail Tracked 48 parcels and £12.00 for UKMail/DHL Nest Working Day.


Smaller items

Items that fit within Royal Mail International Tracked Medium Parcel parameters (59cm x 17cm x 15cm weighing less than 2kg) can be sent to most countries outside the UK.

For example up to 3 of our smaller 18” wingspan kits can fit into one of these parcels.

A parcel like this currently costs around £14 to Europe and around £18 to send to the USA and will take up to 3 weeks to arrive. This is because Royal Mail hands over the parcel to the local Post Office service for your country who have to clear it through customs and then deliver it to you.

The Royal Mail tracking code also transfers over to the tracking for your country’s postal service.

Larger items

For items that do not fit within Royal Mail International Tracked Medium Parcel parameters, we use standard international couriers such as DHL, FedEx and UPS.

These companies use something called volumetric weights to calculate the cost of shipping.

For example, a Balsa Basics RC bundle kit that measures 102cm x 34cm x 16cm and weighs 2.5 kg is actually calculated at 14kg!

This makes these very expensive to send outside the UK - a large kit can cost nearly £40 to send to France.
