Half A Twin (oz2905)
About this Plan
Half-A Twin. Twin engined control line model.
Quote: "It can be said that at one time or another almost every modeler has had the urge to build and fly a twin engine job - for 'twins' are really different, fun to operate and draw attention the way honey draws flies. For most this desire has never been fulfilled, due to several good reasons; one main one: twin engine operation has been considered expensive, complicated by gadgets and usually involved a complex model if it were to be attractive.
Nevertheless, the desire for one is still there. The Half-A Twin is believed to be the model that will allow even the most skeptical die-hard to realize said desire. With this design, we have tried to incorporate the answer to all the objectionable problems which have been present.
The answer to the expense problem comes with the use of Half-A engines. Most of us have one or two on hand anyhow, and with the Twin they do not necessarily have to be of the same make or power, allowing even more leeway in powering it. The use of Half-A engines also solves the operation problem as these small jobs are noted for their easy starting and consistent running ability in the air.
In flying the model, it has been noted that you can hardly tell the difference between the effort required to operate the two engines and that required for single engine jobs. Then, too, the performance in the air has been really remarkable; no instance can be remembered when one engine failed without reason. It almost seems that if one engine is operating well it will pull the other through if you should happen to have a false setting!"
Quote: "Here is the Half a Twin from Air Trails issue 12-51. This is a cleaned-up ,full size, plan scan from the treasure chest. Nice and small, both file size and model size".

Thanks to Fernando for help and the model pic.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
