About this Plan

New Era II. Radio control pattern plane, for .29 to .45 power.

Quote: "The New Era I (oz8042) has proven to be a fantastically successful aircraft. A great number of them have been built and flown around the country. In fact, probably more New Era's have been built than almost any other aircraft from a magazine plan. It seemed natural to us, then, that we should pursue the New Era and develop another aircraft that might gain your acceptance as well as the New Era I.

The New Era II is the result. It is an exact replica of the New Era I, but scaled up to a larger size to satisfy the urge for a little larger aircraft. The II can be flown marginally with .19 size engines, but it can also take a .45. The wing area is 546 square inches, and the all-up weight should be between four and five-and-one-half pounds. There is no doubt that some of you builders will want to put a .60 in the nose, and this can be done, as the nose of the New Era II was made large enough to take almost any size engine. If you are going to use a smaller engine, then use a spacer behind the engine mount, as shown on the plans, or move the firewall forward. Keep the prop in the same location as shown on the plans and adjust the location of the firewall to suit your engine size and type of engine mount.

The structure of the New Era II is strong enough to take any size engine, and almost any G-load that you impose upon it. The original prototype was designed around the fabulous OS Max .40 racing engine. This engine really has lots of power. While it may not have quite the top end that the K & B .40 has for all-out racing, it has lots of power and the ability to swing a large or small prop. In addition, it can be idled down to tick over with the best of them. Uncle Don told me about his lugging a 6.5 lb. shoulder wing Vics Custom Trainer around the sky with speed and ease, so we decided to use this engine in the New Era II. The combination is terrific.

The New Era II is very simple to build and the entire structure can be fabricated in one evening. The plans show a foam wing for the New Era II and this was what was used on the original. You can build a built-up wing if you desire by following the same type of construction that was employed in the New Era I wing. Either way, the wing is simple and doesn't take very much wood.

In keeping with the theme of the New Era, several new ideas were tried out on this model..."

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.
