About this Plan

SE5. Radio control 1/6 scale WWI biplane fighter.

Quote: "Ten years ago only the most foolhardy modeler would build an exact scale RC model and expect to fly it for very long, The unreliability and constant tuning required together with the lack of functions available today made a project such as this impractical. Those of us who have been down the road of the RK-61, ma. meter, portable radio batteries, key on the end of a lead, (remember) can really appreciate how good we have it today. The biggest problem these days is to remember to charge the batteries.

Reliability and precise proportional control now make scale modeling completely practical. This is especially true of WWI planes. These for the most part have a less than ideal nose moment arm. Any of the rotary engine powered planes usually have a very short nose. This makes it necessary to build everything behind the center of gravity as light as possible. Built up fuselages and tail surfaces are required here. The resulting structures are quite fragile and a crash of any consequence will usually result in a washout.

This is where our modern equipment enters the picture. With its very high reliability, the weak link now becomes the pilot.

Choosing a plane with an inline or V type engine has its advantages. They have a longer nose that makes it easier to locate the center of gravity. The engine can be fully cowled in a nose with so much less frontal area.

I built the SE-5 especially for the Rhinebeck contest. At 2"-1' scale the size is ideal. 53" wingspan and 1040 square inch wing area. At 8 lbs a Merco .61 handles it with no problem at all..."

Update 18/01/2014: Replaced this plan with a much clearer version at 400dpi thanks to JJ.

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

    ScaleType: This (oz1290) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

I have attached two photos of my SE5 from Outerzone plan by Nick Ziroli, not quite finished yet but I will finish off after the maiden flight [more pics 003, 004]. The model is powered by an outrunner electric motor, and 5000mah lipo 6s battery.

Added another nice pic of the Ziroli SE5, thanks to AlanDavis [more pics 005].

Your Se5 looks great. I also built this model and used a Saito 72. I fiberglassed and painted and doped it. I even painted the roundals. Do you have any completed pictures to add?
I will add pictures of mine after I finish more detailing. Mine came out tail heavy. So I will also add that the tail must be kept as light as possible. I overbuilt mine by using some hardwood in the tail.

* 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.
