About this Plan

Kittiwake. Radio control sport floatplane. Wingspan 47-3/8 in, wing area 334 sq in, for .19 to .28 engines and 4 channels.

Discontinued kit from Top Flite.

Note this here is the Kittiwake as it appeared when kitted by Top Flite. The design was first published in Nov 1986 RCM, see Kittiwake (oz11860) for an alternative plan, which might help resolve problems with missing parts / information.

Direct submission to Outerzone.

Quote: "INTRODUCTION The KittiWake, proof-positive that there can be more to R/C seaplane flying than just take-offs and landings! Top Flite Models is sure that your KittiWake will provide you with hours of flying fun and performance.

Realistic, finished flying weights of 3 to 3-1/2 pounds can be expected when the model is built to the following instructions. Our prototypes were all covered and flown with Monokote® coverings. The covering instructions will give you the details of how we accomplished the few extra precautions that should be exercised when covering a seaplane.

Engine selection for your KittiWake is important. Our prototypes have been powered with a variety of engines, ranging from .19's through .28's. The KittiWake that is shown in the ads and on the label of your kit has a OS .25 FSR installed with a Mac's muffler. This has been an excellent combination, providing lots of power at the top end while offering an excellent and reliable idle. A reliable idle is an absolute must! Face it, your KittiWake will have to spend a portion of each flight taxiing on the water and without a reliable idling engine, you better have access to a boat to go out and get it when the engine flames out. Take extra time to work on the idle of the engine you choose - it will pay off later.

While on the subject of engines, it is worthwhile to point out that the physical mounting of your engine does not necessarily have to be a side-mount, as shown. Your engine can be mounted up-right, at a 45 degree angle, even inverted (although we do not necessarily like an inverted engine in a seaplane due to potential flooding problems). Generally speaking, the use of a muffler on your engine is highly recommended as it greatly enhances the idle characteristics as well as serving to keep you on good terms with people who may also be at your flying site! Therefore, mounting your engine in the nose of your KittiWake should take into consideration the positioning of the muffler. Mounting the engine upright or at a 45 degree angle allows the use of most engine's stock muffler set-ups. Side mounting the engine, as we did, most usually requires a replacement muffler (one with a longer header) or a header extension. Our prototypes all used fiber-filled motor mounts, sized for whatever engine chosen for the airplane. Your local retailer should be able to supply you with the correct mount for your engine.

PRE-CONSTRUCTION NOTES The KittiWake, like other Top Flite kits employs the use of die-cut wood to ease the task of construction, parts fit and identification. The dies used for this kit have been rigorously checked for absolute accuracy and should provide you with excellent fit. Die-cut parts should be carefully removed from their sheets by first lightly sanding the back of each sheet of parts and then carefully removing each part. Use a light garnet paper for the sanding and keep a sharp hobby knife with an X-acto #11 blade, or equivalent, handy for assistance in removing any parts that might not have completely cut-through by the dies. Parts which oppose one another and must be precisely uniform - such as ribs, etc - should be carefully matched after their removal from the part sheets. Matching is the process of holding the opposing pieces together with either pins, tape or spot gluing and lightly sanding the edges of the parts until they are identical. A sanding block with light garnet paper is most useful for this and other phases of construction.

Your building surface should be at least large enough to accommodate the wing. This surface should be as absolutely flat as possible and yet be able to accept pins easily. We have found that a product such as Celotex fiber board works quite well for this purpose. Another good surface can be found in most well-stocked hardware stores - a 2' x 4' fiber board ceiling tile. These are quite inexpensive..."

* 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.
