Product Details


Are you looking to power a balsa model up to around 20" (500mm) wingspan?

If you prefer a brushless set up with standalone servos, this is the option for you.

This pack can be used to convert one of our Magnificent Flying Machines rubber-powered free-flight kits into an electric-powered, radio-controlled model although some modellers may prefer to use ultralight brushed motors with combined receiver/inline servo "bricks".

This is NOT a pack designed for complete beginners - we assume that you know what you're doing!

You will need to be able to solder, understand brushless motors, ESCs, servos and how to connect them as well as how to convert a model originally designed for rubber power.

Fettling will be necessary!

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.
