Sharkface - 22in wingspan radio control model for up to 1.5cc engines and rudder only control.
Quote: - "Eric Clutton reveals in his own inimitable way an approach to small-field R/C aerobatic flying on a low budget, introducing the full size plan ' Sharkface' for .049-.09 (.8-1.5cc) engines ...that practically takes care of the selection of the radio gear: all transistor, relayless and with a simple escapement, all operating off 3 volts...
To fly fast we must have plenty of power. A heavy model will not penetrate unless it has a powerful engine fitted - it's the engine capacity in relation to the model size that counts. Also a fast flying model will hit the ground with quite a bump if something goes wrong, so it must have built in bounce...
Wings are a necessary evil on RC models, they are often tricky to build and are the first component to break, so my wings will be as small as possible - consistent with a reasonable glide. Built up wings do not have to be flimsy. A glance at the Sharkface plans will tell you this! The prototype was covered with heavywight tissue and has yet to receive any structural damage apart from the odd scrape where it has clobbered the runway...
For those who like to live dangerously the 1.5cc diesel is the obvious choice, but be warned - you need hair on your chest for this one! Sharkface does not become vicious however, and things happen only slightly faster. Rudder movement may habe to be reduced for the less intrepid."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
