About this Plan

Hammerhead. Radio control pattern plane, for Merco .69 power.

Quote: "We are pround to present this outstanding example of master craftsmanship and winner of numerous awards, including the RCM Editor's Trophy.

And so it was by me. After years in modeling, with the last few in radio control, I had to try. Experience with several of the recent favourites, plus a few ideas of my own, sparked the Hammerhaed. I wish I could give you a learned discussion about why things are as they are, momentwise and all thta, but the plain facts are that I drew my dream unscientifically, decided it probably wouldn't fly, and then built it anyway to get it out of my system.

The first flight was conducted in secret, of course. Darned if the thing didn't go right off, and no witness. I had a mazing luck for about 25 hours of flying, and then, prang!

The second Hammerhead had 'improvements'. At 7-1/4 pounds it was deliberately heavier by 3/4 of a pound. I substituted a lrgger engine (which shall be nameless) for the Meroc 49 which served so well in the first airplane, revelling in the heady promise of greater power at no increase in engine weight. Then several interesting things happened, some good and some bad...

You can see from the plans and pictures that some of my ways of building are different. The fuselage can be built in the conventional way if you like. You're on your own. I use fibreglass. I have made several fibreglass bodies several ways, but I like the method described here the best..."

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.
