Quote: "From Guantanamo, Cuba, through efforts of Dorita comes this jaunty little control line trainer plane. Profile Pete, by Alexis Poyato.
Profile Pete is the result of my girlfriend Dorita asking for a model that would be easy to handle and fly. Her interest in modeling began when she first met me, for that was the first time she'd ever seen a model airplane. She got so excited about modeling I had to teach her to fly with an old control line trainer I had. After she piloted a few big models successfully, she wanted to know if I could design a small model with scale-like lines and one more easy to fly than the big jobs. So I designed Profile Pete which fulfilled the specification perfectly.
Wingspan of the model is 25 in; weight without motor is 6.5 ounces; it is powered with an OK .099 engine. You can use an OK .074, too. With floats we fly it from a river near home within city limits and it is a big attraction. Construction begins with the wing. Cut the ribs from 1/16 sheet balsa and tip plates from 3/32 sheet stock. Then cut the four 1/16 plywood spar joiners. Assemble the wing flat on your bench and when dry cut at center and cement in the joiners, propping each tip up with 1 blocks. Cement on the tip plates and the 1/16 sheet pieces in bottom of the center section of wing. Bend the alumi-num brackets for the struts; cement the guessets on each side of the wing. Cement the lead weight in iight wing tip. Cover entire wing with Silkspan and give it two thin coats of clear dope. Bend the lead-out guide fro,rn 1/32 wire and push it into the 3/32 tip plate; bend the ends and push them hack into the balsa again, and cement all this well.
Cut the fuselage from 3/8 sheet balsa; make the cut-out for the bellcrank. Round off all corners by sanding a 'V' cut where the wing will mount. Bend the 1/16 landing gear wire and fix it in place with aluminum brackets and two 3/32 x 5/8 bolts. Cut the motor mount from 1/4 in plywood and cement well in place.
Cut tail surfaces from 1/16 sheet stock; join stabilizer and elevator with fabric hinges and cement control horn in place. Offset rudder % to right and cement in place. Bend 1/32 wire tail skid, push into fuselage and reinforce joint with gauze. Connect the 1/32 wire pushrod to horn and bellcrank. Make a vertical groove on the right side of the fuselage for the 1/16 wire bellcrank pivot, pass the crank from left to right through the fuselage cut out, put the pivot wire through the bellcrank hole, add two washers and cement pivot wire in place.
Add flexible lead outs and pushrod guides. The latter are made from pins loosely bent over pushrod with round-nose pliers. Make the struts from 1/8 x 3/8 strips and sand corners round. Cut the aluminum strut bracket and fix it to bottom of fuselage with a wood screw. Cement the wing at center; bind the strut ends with thread to the brackets and cement everything thoroughly. Give the fuselage and tail surfaces three coats of clear dope and sand smooth. Paint the entire model with one coat of STA. Give a second coat to front portion of the fuselage.
If you want the seaplane version, make a pair of floats from 1/16 sheet balsa. Bend the 1/16 wire rear strut as shown on the plans. Paint the floats yellow. To change from land to sea operation you only have to unscrew the wheels, screw on the rear strut, then hold the floats in place with rubber bands.
Use a square or wedge tank and a 7 diameter x 4 pitch prop. You can take Profile Pete every place you go - to the flying field, to the parking lot, to the river, lake or sea. And you can thank Dorita for the fun you are going to have flying this model."

* 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.
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.
