About this Plan

Aries. Slope soarer for single channel radio control. June 1958 Aeromodeller.

Quote: "A 6 ft-span radio-control slope soaring glider by George Upson.

RADIO CONTROL FLYING first stirred my interest early in 1957 and having little actual radio knowledge I felt sure that useful experience could be gained by installing such equipment in a glider. Slope soaring was the obvious method of obtaining flights of any duration, and knowledge gained flying an APS Archangel (oz3935) with radio at 2-3/4 lb weight eventually led to the design of Aries.

The prime design factor for slope soaring is good wind penetration, and for this reason a flat-bottomed wing section is used giving the model a fairly fast flying speed. Other components are orthodox, the tailplane area being 25 percent of the wing, the moment arm three wing chords, and the dihedral 10 percent. Tip dihedral is used in order to simplify the two-piece wing joint.

The fuselage was made as strong as possible and designed around the Hill receiver and Mighty Midget Servo unit which means that there is plenty of room for any conventional system.

Single-channel control with rudder only is employed, utilising the Laurie Ellis Canadian Actuator, described in the February, 1957 Aeromodeller. This provides selective control, i.e., one signal gives left, two right, or vice versa, with automatic return to neutral on release of the signal. Sellotape was used for the dead spots on the gear wheel which provides a means of finding their best position.

Construction. Building is straightforward, but the following points should be noted. Washout in the wing should be incorporated when building. Fuselage top sheeting is added after installing the control rod. It is essential that the rudder control linkage operates quite freely. No centring springs are used on the rudder control surface as servo motor overrun is negligible.

Flying. Trim with CG between 50 percent and 55 percent of wing for straight glide below the stall using the rudder tab and tailplane packing. If you move the CG further back than 55 percent, flight becomes undulating in stall recovery. Trim as above is standard for winds of up to 10 mph; for stronger winds move the C.G. forward and adjust tailplane..."

Notes

* 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.

Scaling

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.
