About this Plan
Flamingo. Radio control sport seaplane model, for .15 upwards.
Quote: "A tried and true flying boat for engines of .15 to .23 displacement, this water bird will give spectacular take-offs and many a smooth flight. Flamingo by AG Lennon.
The Flamingo utilizes the planing-tail-hull formulae. It is of rugged design, and weighs 70 oz, with a wing loading of 20 oz per square foot. It has sustained one crash landing involving a chimney and a tree with minor damage.
The original was powered with a .15 Torpedo and this is the minimum power recommended. A .19 or .23 motor can also be used. The nacelle as drawn will accommodate all 3 sizes, although with the .15 a thicker thrust adjustment block will be needed. Motors should be installed with adaptor plates for firewall mounting and beam mounting legs removed. Props recommended are 9 x 6 for the .15 and 10 x 6 for the .19. With the Babcock motor-control unit, high speed revs of 8500 rpm and low speed of 4000 rpm were obtained with the .15.
This model has beautiful flight characteristics. Turns are smooth, penetration is good and the climb with the .15 surprisingly good. The design is clean for a flying boat, but the hull, nacelle and wing floats add plenty of drag so that the power-on, power-off transition is hardly noticeable. Water take-offs run to approximately 150 ft without use of high-power fuel.
Radio and escapement equipment is all Babcock. Receiver is the BCR-3; the primary escapement the Babcock Mark 11 Super Compound, operating rudder and giving up-elevator. Flaring the water landings with up-elevator are a never to be forgotten thrill. The Babcock Universal Motor Control Escapement is used for motor control, high and low speed.
The original design of the Flamingo did not include a water rudder. However, when taxiing at low speed on the water, the air rudder is ineffective. A balanced water rudder, as shown, was installed and after several trial sizes had been tested, this one proved satisfactory..."

* 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.
