The E20 class is a very simple 20 inch wingspan, free-flight aircraft powered by a small electric motor and prop that runs for a defined time, with the model then gliding back to the ground (or out of sight).

Back in early 2019, Kevin Wallace (former owner of SAMS Models) and Andy Sephton designed a model for use in E20 competitions.

This design proved very successful in competition and SAMS asked us at the time whether we’d be happy to laser cut the parts for the E20 so that they could sell the kits. 

We have now re-released the kit with a few minor tweaks to improve the fit of the laser cut parts and corresponding plan.

The kit does not include the motor, prop, battery or electronics.


  • Balsa sheets with precise laser cut parts and strip wood
  • Full size plotted plan
  • Parts reference sheet
  • 2 x 3/32" x 300mm square balsa strip
  • 3 x hardwood cocktail sticks
  • Covering tissue
  • Easy Sand PVA glue

Only Suitable For Ages 14+

Choking Hazard - Contains small parts, keep out of reach of children.


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.
