4ch SHARKFACE R/C Plane
The very simplest of weekend builds, but not a sedate model by any means! This model is a tribute to Eric Clutton's 1965 "Sharkface" adapted for electric power and 4 channel R/C. This models flies like the wind, and is very aerobatic. It's an ideal fun flier to chuck in the car boot, for a quick scream round the common.
This is a great beginner build. With sheet sides, you can expect a speedy build time with little faffing around. Everything tabs together which makes getting the fuselage straight and true rather foolproof.

Fit it with a verity of power options. There is plenty of room for any small outrunner/esc combo. The motor can be bolted straight to the nose which makes the build even quicker. If you have a spare set of electronics lying around, building this plane to make good use of them is a must.

The kit was sent out quickly and packaged well. The wood quality and laser cutting on our kit was excellent. Our kit came very complete, including all required push rods, clevises, and even original DuBro control horns. White tissue for covering is included, but we used iron-on covering film (Oracover light). The plan is very well printed and contains build instructions. Building is a breeze, it took us two weekends, with most of the time spent on covering and installing the radio gear. The fuselage is super simple as it has a rectangular shape. The wings are small and flimsy so great care must be taken, especially when sanding. Fit of all parts was superb. The lock for the hatch using spring steel is very old school yet simple, cheap and works very well; love it! The kit is designed around three Hitec HS-55 servos. We used HS-55 for Aileron and Rudder, and a KST DS113MG for Elevator (because that's what we had on hand). Even though technically the DS113MG is the same size as the HS-55, we couldn't use the DS113MG for the ailerons as the cable exit on the servo was at a different location and interfering with the limited space in the wing. It would have worked with a bit of trimming; just be aware if you are using non HS-55 servos. Our plane is powered by a EMAX 2204 / 2300KV (very old design) mini-quad motor and a Gemfan 5x4 prop. We run an old 25A ESC (max current is about 11A with that motor/prop). Battery is Zippy Compact 3S 1300, which when pushed all the way back balances the plane perfectly. AUW is 320g (Battery is 120g already). We get about 13 minutes flight time out of a battery. It flies like you would expect from a plane that was originally designed for single-channel RC. It is very stable for its size, but affected by gusts due to its low weight. Launch and landing is without drama. The old 2204 motor on 3S is OK power wise, but the plane is certainly not overpowered. It likes to fly fast rather than slow. At high bank angles it drops steeply; when you drag it through the corners with a lot of elevator it likes to climb and almost go into a stall. It can do loops and rolls, but 3D is certainly not what it wants to do. If I would build it again I would use stitched hinges instead of tape for the hinges. I may also build it rudder and elevator only; the ailerons are not really necessary for this design yet add a lot of complexity and weight. All in all: a great quality low-cost kit of a vintage design. As the say: a blast from the past! Werner (aka LANE Boys RC)
