About this Plan

Macchi C.202. Control line profile stunt trainer model.

Quote: "For practicing the pattern here's a sort-of-scale profile job for 15 to 25 size engines. It is also popular in the West Coast Class A Stunt event. Macchi C.202, by Scott A Conradson.

In our search for the all-around airplane, we find that it must meet the requirements of being inexpensive and easy to build, and its flying capabilities must be in the full stunt range. The low-cost factor can be obtained by designing the model around a 19 engine. But after testing several present kits, it was found that this size of airplane flies more like a brick. The kits seem to lack sufficient wing area to achieve a flyable wing loading. We therefore designed the aircraft with double the area of kit planes, yet almost the same weight. Now we had only to achieve the right configuration, as scaled-down full stunt ships' moments were not usable.

After having designed several models to meet these requirements, all with only limited success, a member of our club, Dick Oglesbee, brought out a new aircraft for the WAM 'A' Stunt event. This plane came close to what we wanted. Using it as a starting point, we enlarged and generally redesigned it into the plane presented here - the Macchi C.202.

The Macchi has been so successful that the fuselage and wing tips have been changed by various club members to produce such variations as an Me 109, a P-47, a Boulton-Paul Defiant, and more. We use ours for sport flying and practicing the stunt pattern. It is also a real crowd pleaser when used in Slow Combat. The Macchi is an excellent plane with which to learn the AMA stunt pattern. If you are ready to begin stunting, try one!

The Macchi has flown competitively on engines from a 15 up to a 23. I would recommend an OS 19, or for a really hot ship a Supertigre 23. The new Fox 25 is also good. The advantages of using an 'A' size engine are many. It costs about two thirds of an equivalent 35 to buy and run, and the cost of the aircraft is also less. The main reason that such a small engine can effectively power an aircraft as big as a Ringmaster is the plane's light weight. Therefore, wood selection is important. All wood should be firm, light 'C' grain balsa (the balsa that is speckled), except for the planking, which should be 'A' grain (the wood with long grain marks that bends easily). The airplane can be modified to suit individual tastes. Do not change the moments or airfoil, but try your own original fuselage outline drawn over the plans. This is a good way to begin learning how to design your own. Besides, it's fun to take your original design out to the flying field.

Construction: The piece of wood used for the fuselage is the most important single piece in the entire plane. It must be firm, very light 'C' grain. If you cannot find a good piece of 1/2 in balsa, then use a 3/8 piece. Trace the fuselage outline onto it, and cut it out. Do the same for the 1/8 ply fuselage doublers and the 3/8 x 1/2 in hardwood engine mounts.

Epoxy the engine mounts in place; then epoxy on the doublers. When they are dry, use a block plane to plane the fuselage to an oval cross section. This step will lighten the aircraft considerably, and is a must for optimum performance..."

    see Wikipedia | search Outerzone


    ScaleType: This (oz13421) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Macchi_C.202
    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.

Notes

* 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.

Scaling

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.
