Quote: "Cessna-152 Construction: Construction of the fuselage, wing and tail surfaces is easily accomplished. The fuselage framework can be accurately by inserting the longitudinal fuselage members and bulkheads into the notches in the plywood pieces. Use your favorite epoxy glue to adhere the members individually as you assemble the component parts. The wing and Stab. are similarly constructed using the plan as full size plan. Install the radio system as indicated on the full size fuselage drawings and the instructions provided with your radio. Spruce pushrods are included in the kit as is the piano wire for servo and control surface attachment. Clivis are not provided in the kit and must be purchased separately.

Fuselage Construction: Glue firewall F-2, fuselage formers F-3 through F-9 into the notches in the sidepanels F-1. Sandwitch and glue the tail piece F-10 between the tail end of both sidepanels. Glue ENGINE MOUNT F-11 and reinforcement F-12 into the place with epoxy. Put and glue 1/4 x 1/4 balsa stringers into the notches in the formers. Glue 3/8 tapered balsa shoulder stringers F-1 and F-14 into the appropriate place. Glue plywood kells F-15 and balsa F-16 into the place. Glue F-17 to the F-15. Glue F-18 through F-26 into the correct position. Plank top and bottom of fuselage with 3/32 balsa sheets. Glue F-28 through F-30 to the front of firewall F-2.

Cut the plastic windows, wheel pants and cowl parts from molded sheets as indicated inside of the molded sheets. Construct the plastic cowl with liquid cement contained in the kit. Trial fit the plastic cowl parts and if all fit well you're ready to cement. Fix a few point with scotch tape to keep the actual form and glue with liquid cement. The best way to use this is have a small paintbrush, clip it into the liquid cement and while holding the parts together allow the cement to run between them. Hold for a few seconds and they will be together. Glue the side windows and windshields to the fuselage with vinyl cement (not contained). (If you finish the fuselage with heat shrink plastic film, attaching the windows and windshields must be done after the covering.) Attach the cowl to the F-30s with self tapping screws.

Wing Construction: Glue ribs W-1 through W-9 into the notches of leading edges W-12 & W-13 and trailing edges W-10 & W-11. Take two 5/32 x 1/4 spruce spars and place into the notches in the ribs. Join two wing halves with W-14 and W-15. Glue ply W-16 and W-17 into the position. Glue balsa ribs W-18 through W-22 into the center wing. Put and glue 1/8 x 1/4 spruce stick into the notches in each ribs. Glue W-23 and W-24 into the place. Glue the spar webs W-25 through W-30 between top and bottom spars. Glue bellcrank mount W-33 into the place and reinforce the corner with 1/4 x 1/4 balsa stick. Glue wing strut hold block W-32 into the place with epoxy.

Attach the bell cranks on the W-33s. Put the aileron push rod into the wing as shown in the plan. Glue W-31 to the place. Plank top and bottom of wing with 1.5mm balsa sheets. Glue rib caps to the each ribs. Glue wing tip W-34 into the place. Glue W-35 and W-36 to the rear of center wing, 5/32 x 3/8 hard wood to the front of W-17. Round the leading edge and smooth whole surface with sandpaper. Attach the ailerons W-37 to the each wings with hinges. Make the wing strut with 1/4 x 5/8 spruce bars for fit the plane as shown in the plan. Fix the strut ends to the wing's W-32 and fuselage's F-17 with self tapping screws..."

Update 18/4/2023: Added main landing gear scan, thanks to Dwayne Josefski.

Quote: "Morning, My father is currently building a Pilot Cessna 152 from OZ plan oz3615 and he has identified that the main landing gear is not shown on the plan. So please find attached a photocopy (true size) of one of the original from my kit. Keep up the great work. Regards,"

    ScaleType: This (oz3615) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Cessna_152
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

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.
