About this Plan

Coquette. McCoy 9 diesel powered stunt model. Dick Carlson, MAN September 1955.

Quote: "Big ship performance in .09-powered stubter resulted from this designer's need for an 'apartmant-sized model' Mac diesel does it.

When the McCoy '9' Diesel was marketed, we saw the possibility of using the motor to good advantage in an 'apartment-sized' model. Since our interest is primarily with stunt flying and space restrictions prohibit the building of a large stunter, the Diesel seemed to be the ideal answer to our problem.

If the Mac Diesel lived up to its power-size dad, we felt that it should be able to pull a good sized design capable of big model performance. Consequently, we made our model considerably larger than the average .09 stunt job - the end result being a ship that turned out to be a full-pattern flier.

Our first few flights were with the Diesel running rich and the model flew all but overhead eights. When the motor had had sufficient running time, we leaned the needle out and found that we had a superb stunter which flew everything as well as a big job, which speaks well of the smaller 230 sq in wing.

The model goes together very easily, since since fairly standard construction is used throughout

Fuselage. Cut the sides and F3-F6 formers from medium 1/16 and 3/32 in sheet. Cut the nose doublers from 1/32 in plywood, join them to the inside faces of the balsa sides, then cement the 3/8 in sq hardwood motor bearers to the doublers (flush with the top edges). Cut out the 3/32 in ply formers (F1 and F2) and attach the landing gear to F2 with small machine screws and tin straps. Join the two sides at the nose with Fl and F2, then add the remaining F3-F6 formers.

Wing and Stab. First join the plan drawings at XX to give the full wing layout. Cut out and cement all ribs (med 1/16 in sheet) to the lower hard 3/16 in sq spar, noting that the left wing panel is longer than the right. Now block up the rib ends and cement the top spar in place..."
