About this Plan

Seamaster. Radio control seaplane.

Quote: "The late Ken Willard was a prolific American designer of model aircraft & his Wavemaster Seaplane must be one of his finest creations. This design was only ever produced as a kit, and as far as we know, no plans exist. However he later produced the Seamaster which seems to have corrected some faults in the original Wavemaster design and Seamaster II which again was kitted.

All three model are very similar. The kits are no longer available and the companies ceased trading many years ago. The only external difference is in the tailplane location. The Wavemaster tailplane is in the normal position but the Seamaster series have the tailplane on top of the fin, well away from the water surface. Also the Seamasters were much lighter.

As a kit, Wavemaster had a moulded fuselage in two halves. If you are considering a flying boat or seaplane you can do a lot worse than this proven iconic design. It has a considerable following in the USA with larger & smaller designs, some with electric power.

The plan is widely available from various sources on the Internet but this version has been more or less totally redrawn and is offered as a PDF file for ease of printing.

The model is of straightforward construction with an easy to build parallel wing. The most important point is to make 100% sure the hull is watertight with a good waterproof varnish on the inside, done after construction by pouring varnish in through the forward hatch, fully coating the insides, and the letting most of it drain out again."

This is a modern redrawn plan in PDFvector format.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

I have built this particular plane and modified it by making it a v hull. Apart from that it is the best plane I have had and flown with hundreds of flights logged on water and land.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
