About this Plan
Aquabird. Radio control sport flying boat model. Unconventional design inspired by a (ground-effect style) Lippisch flying boat prototype.
Quote: "The Aquabird design is a culmination of many years of designing models of different shapes and configurations. The idea for this model came to me after I saw a picture of a strange looking plane or flying boat in a magazine several years ago. The wing shape was reverse delta with anhedral and large sponsons on each wing tip. The engine was mounted behind the cockpit high on pylon, in tractor fashion. The stabilizer was mounted on top of the fin. Apparently, this was a proof of concept design to be used on a much larger version of a transport vehicle to fly or skim over the ocean surface.
The design came from a well-known German designer of flying wings, Dr Alexander Lippisch. I have no idea what the outcome of the tests were. Obviously something was not there since we do not see anything of this type flying. This did not bother me as the seeds of this design were planted and I started to make sketches of my version.
The first version had the same type of wing as I had seen in the magazine but I eliminated the T tail. The engine was put in the front and had a single fin at rear. The sponsons were placed under the wingtips. The elevons and the rudder were used for controls.
After I built the model, I went to a nearby lake and tried to taxi on the water surface. That was fine, however, the problem developed when I applied more power. The tail would come up, but at the same time the nose of the sponsons would start digging in causing the nose of the plane to pitch down..."

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

* 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.
