Product Details


Wingspan: 13" (330mm)

This laser cut, pre-coloured, balsa wood profile kit can be enjoyed as a simple rubber-launched "chuck glider" or as a rocket-powered, free-flight glider.

Super simple construction and containing everything you need to build it, this kit is remarkable value for money.

If you plan to fly using a rocket motor, you can use either the TSP L-2 or the L-2HP for longer, more powerful flights.

(Please note: some of the early production kits have a discrepancy in the plans/instructions over dihedral settings. The correct dihedral is 10-12mm at each wing tip)

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

We are in the middle of nowhere and so our Royal Mail collection is at around 1pm.


An order placed before 12pm on Monday should be with you on Wednesday.

An order placed after 12pm on Monday should be with you on Thursday.

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


An order placed before 10am on Monday should be with you on Tuesday.

An order placed after 10am on Monday should be with you on Wednesday.

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 Next Working Day.


Royal Mail considers Northern Ireland, Scottish Highlands and UK Islands as part of the UK and so does not charge a premium for deliveries.

Pretty much all other UK couriers have surcharges for deliveries to the following postcodes: IV, HS, KA27-28, KW, PA20-49, PA60-78, PH17-26, PH30-44, PH49-50, ZE, BT, IM, TR21-25

If you live in one of these postcodes and the parcel size of your order is outside Royal Mail's dimensions, you will have to pay a surcharge.

Our system is not clever enough to work this out and so if your order attracts a surcharge, we will contact you before despatch to see if you would like to pay the surcharge and proceed with the order or cancel and receive a full refund.



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.
