Pirata Twin (oz6698)

About this Plan

Pirata Twin. Sport twin-engines model for control line.

Quote: "From Cuba comes this jaunty 'Pirate' designed for young Sunday Flyers; 2-engined control liner breezed through 6-mo. test program with not a single crackup!

Who said profiles are not beautiful? Look at this sleek 'Sunday Special' and you will think differently. This is a beautiful, simple and inexpensive model that will give you long hours of fun and action. Although this is my first twin, the flight results pleased me so much I'm tempted to abandon the single-engine field. I recommend it as your first twin. If you install the arresting hook, the fun will increase. The only extras you will need are two sandbags, a length of Nylon line and a pair of hooks to anchor the sandbags in the ground. Install some device in the model to rev-down the two motors or stop one for landings.

Wingspan of the model is 32 in, weight without motors is 8.5 oz; it is powered by two OK Cub .099's. It can be flown in two OK .074's or .049's with little modification, but what the doctor recommends is a good pair of OK .099's.

Begin construction with the wing. Cut the ribs from 1/16 sheet balsa. Remember to cut out 1/16 strips on top and bottom of six ribs to accommodate the center section covering of 1/16 sheet. Punch holes in left ribs using the metal top of a pencil with the rubber removed. Cut wing tips from 3/32 sheet and insert 1/16 aluminum tubes for lead outs. Select good, straight stringers for LE, TE, and spars, and assemble wing in conventional manner. Add small 1/8 gussets to wing tips and remember to put the weight in right wing tip. Cut bell-crank mounts and spacers from 1/8 plywood and cement the mounts well in place. After dry drill the 3/32 bellcrank pivot holes. Hook up the 1/32 leadouts to bellcrank and install this unit with the 3/32 bellcrank pivot; remember to in-sert washers and spacers top and bottom.

Install the pushrod and cover wing's center section, from motor to motor, with 1/16 sheet, leaving a small opening for the pushrod in the bottom. Outer panels of wings can be covered with Silkspan. Now cut the fuselage and motor nacelles from 3/8 sheet and make cutouts in them for the wing. The cabin can be made from scrap stock. Make the cut at rear of fuselage for the stabilizer..."
