Stits SA-9A Sky Coupe

Grid Leaks's Stits SA-9A Sky Coupe

Stits Skycoupe - Scale model of the home-built plane 3 channel with 54 inch span and 477 square inches area, for .15 to .19 power and RC. Here is Jess Krieser's Stits SA-9A Skycoupe from Grid Leaks newsletter July/August 1966. This model was featured on the cover as shown.

The Stits Skycoupe. This semi-scale features a fin and rudder area that will really give you maneuverability. By R. JESS KRIESER. Class II R/C pilots who've been complaining about not having enough fin and rudder area to do smooth, axial rudder rolls feast your eyes on the vertical tail assembly of this Stits Sky-coupe! If this doesn't give you enough fin and rudder area to satisfy your appetite for tight rolls, then there's no hope for you in Class II. On to Class III and ailerons?

Builders speculate directional stability and rudder response ought to get from a flying scale model of this unusual design. Jess found that it had unusual wind penetration and directional stahility, and did some of the tightest, most beautiful Immelmans we've seen. A few blips of up elevator puts the Sky-coupe over in its hack, and a single touch of the rudder switch rolls the ship level as though it were rotating about a rod extending through its longitudinal axis. A real hot Class II pilot ought to have a ball with this ship!

One word of caution, though - start with a very small amount of rudder throw on your first flight, and work up to the amount you find comfortable, for if you give it too much throw on its first flights you're liable to wreck.

Plan is clear and scalable although most of the design was originally hand drawn. This plan could use a digital refresh. Only one of the several fuselage formers is shown but the wing only has a few rib styles and are well shown.

Love building and flying. I've always flown on private property and only been involved with clubs twice. I live in southern Ontario Canada near Niagara Falls. I build at least one plane a year. I am fairly new to 3D helicopters.

My name is Donnie and I've been flying planes, helicopters, racing cars and launching rockets since 1970 when I got my first U-control plane from Carl Goldberg models. I finally got my first RC in 1983 a Cessna 182 kit with four channels. My favorite planes are 3D of every sort of aircraft. Anything capable of punching holes in the sky. IRL I work with programming and I use the skills I have to build my own designs and plans. Thank you for the donations.
