About this Plan

Sonerai II. RC scale model homebuilt, for .10 power.

Quote: "The full scale Sonerai II is an experimental aircraft designed by John Monett (formerly Monett Aircraft Inc). Numerous aircraft were built from his full scale kits, and many examples may be seen each year at the giant EAA convention in Oshkosh, Wisconsin, which is also the site where the Monett Aircraft Company was located. The aircraft is a two place tandem seater and it is designed to be powered by converted VW engines that are very popular power plants for use in homebuilts.

Several different models of the Sonerai were available, such as single seater, mid-wing, low wing, etc. My model version of the Sonerai H was drawn to the scale of 1/8 that yields a model with the span 29-3/8 in and the total weight of only 30-1/2 ounces.

The short wingspan might seem frightening, but the model is easy to fly and good take-offs and landings are easily performed, is also a perfect model to bring with you when you are traveling for holidays, etc. It is very fast when equipped with a good engine and is also very maneuverable. It has to be flown all the time, however, but this is easy when you have learned to fly low wing models.

The amount or materials needed to complete the model are minimal, I built mine from the pieces in my scrap box! I suggest that you start first by making a 'kit', cutting out all the fuselage formers and wing ribs. Note
that F2A is built up from two pieces of plywood.

Fuselage: Cut out the fuselage sides up to the centerline from 1/16 balsa sheet using light balsa. Mark out the correct places foram formers and glue them to the fuselage sides. Align the center of the formers to a straight line drawn on your building beard to ensure that the fuselage will be built straight and symmetrical.

Add the 3/16 square balsa pieces and the reinforcements in the fuel tank compartment. Glue the rear of the fuselage together and add former. Next, glue the tail group pieces in place making sure that everything is properly aligned before you leave it to dry..."

    ScaleType: This (oz5977) 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.

* 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.
