About this Plan
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 have to be reduced for the less intrepid..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHere is an action shot of Eric Clutton's Sharkface that I built from one of your plan downloads [see more pics 003].

Eric Clutton's famous Sharkface is a classic. Designed as a single channel model for an 049 glow motor, with modern equipment it makes an excellent rudder/elevator/throttle electric powered model, my version was built over a period of 30 days (very quick for me) which shows how simple it is, it also uses mostly balsa from the scrap box. Power is a BRC 140 watt out runner propped to give just under 90 watts running from a 2S 850 lipo. As it only weighs 300 grams (10.5 ounces) this equates to 120 watts per pound and at this level it is very lively indeed and extremely aerobatic whilst the motor, ESC and 30C lipo are operating well within their comfort zones. A great little model [more pics 004-006].

Here's a picture of my Sharkface done in the old Skyleader colours [more pics 007, 008].

Hello Steve & Mary! I recently build one Model from your plans collection, the "Sharkface" by Eric Clutton. Here are some pics [more pics 009-011]. It flies very well and fast (around 110km/h) on a Dymond 2714 Outrunner using 3s 1000mA Lipos and APC 6x5 Prop. Current draw is 12 A on the ground. Mine got very tail heavy, so lengthening the fuselage by half an inch would be a good idea.

* 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.
