Product Details



It’s a warm Sunday evening in June as a light breeze rustles through the meadow’s long grass. 

The sun is still high on the horizon as the unmistakeable yellow silhouette passes in front of it. 

You’re bringing your Cub into land after 20 minutes of sheer flying pleasure. Just yesterday, you had a box of laser cut balsa wood parts, some electronics and that dark yellow covering sitting on your workbench and here you are on finals, guiding your model back into the breeze, flairing it out before a gentle stall into the welcoming sward.

Our Balsa Basics Cub was made for weekends like this.

The build is a cinch with illustrated step-by-step instructions and chunky laser-cut balsa and ply wood parts that slot together before you glue them into place.

Innovative design elements like the super-strong plywood box core that contains your electronics, simplified hinge fitting and self-jigging wing construction make for a foolproof build.

Once you’ve ironed on the included heat-shrink polyester covering and applied the window stickers and stripes, you’re ready for the flying field.

Easy to Fly

And what a docile flier the Cub is.

Simple 3 channel RC means throttle, rudder and elevator are all you need to get this bird airborne. Once in flight, the Cub floats around in a manner that’s perfect for new pilots - a big enough wingspan to see the model at several hundred metres but at speeds that mean any beginner “wobbles” are easy to catch and put right.

The Cub's predictable characteristics and almost "autopilot-like" handling makes it incredibly easy to learn on.

It almost flies itself!

You need only to use small inputs on the controls to point the aircraft in the right direction and most of the time the Cub is happiest cruising along at minimum throttle.

If the mood takes you, the Cub can also perform basic aerobatics such as loops and wingovers.

Flight times with the recommended battery can be up to 20 minutes on calm days.

The large 42" (1047mm) wingspan, lets you take on windier conditions and a pair of quality 2.5" semi-pneumatic rubber wheels make for smooth take-offs and easy landings.

Help & Resources


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.

This is a simple beginner's build with incredibly accurate laser-cut pieces. This enables you to 'dry build' then check all's okay before glueing.

Amazing model. definately designed by someone with many years modeller experience. a very rewarding model. unbeatable as a first model. worth every penny.

Having recently returned to aero modelling and only so far built a couple of gliders I wanted to build an electric powered trainer to re-learn RC flying as its been a long break, therefore I wanted a fairly robust steady flyer, I was bought this kit by my family and it is really is worth every penny, the quality of the wood is very good and lazer cutting is excellent ,far superior than the stamped out kits I remember from the 1970s, all the parts fitted together well and even though I built using aliphatic glue rather than super glue and had to change the sequence slightly it was an enjoyable build, I'm more used to scratch building from plans but this kit was a nice change, it is ideal for a complete novice with the detailed building guide and not having to use a plane or building board but is also a quick build for the more experienced modellers, though I have not flown it yet due to the current situation I'm sure it'll fly well, it balanced perfectly after fitting a battery, the electronic parts of the kit were easy to work out and fit especially as it was my first ever electric powered model, all in all a nice model, easy and quick to build, when finished it looks good too,
