About this Plan

Piper Super Cruiser. Scale model for single channel RC (or free flight). Wingspan 40 in, wing area 231 sq in. For .045 - .074 engines.

Quote: "40 inch wingspan two-in-one Radio and Free Flight Superscale model. Piper Super Cruiser.

A Contest Champ the World Over, Jetco's accurate replica of the Piper Super Cruiser PA-12 incorporates detachable flying surfaces (see adjoining photo) with internal rubber band fixing and speedy 'flat-on-the-plan' building methods.

The design is equally suitable to single-channel Radio Control and Free Flight - with both versions being fully covered on the super-detailed plans.

All makes of commercial RC equipment now available easily fit in the roomy fuselage. the kit features top grade materials - including die-cut sheet balsa, strip balsa, windshield, plywood, dowel, covering material and hardware."

Planfile includes full build instructions.

Quote: "This Model is on accurate replica of one of the USA's best known high-wing cabin monoplanes the PA-12 Piper Super Cruiser. Powered by a 4-cylinder 100 hp Lycorning 0-235-c engine, this 3-seater spans 35 ft 5-1/2 in and has a top speed of 115 mph.

The proportions are ideal for radio control (.049 - .074 engines) and free flight (.020 - .049 engines) flying. Authenticity has been assured by the full co-operation of the Piper Aircraft Corporation, who kindly supplied plans, data and photos of the actual airplane registered NC137803. Noteworthy features of the model are the detachable one-piece wing, struts and tail surfaces.

The K&B Allyn Sky Fury .049, .049 Deluxe and .078 engines are particularly recommended - the .049 Deluxe being featured on the plans. One of the prototype models was fitted with an Allbon Dort diesel (.32 cc), which is the standard powerplant for the British version of this kit (manufactured in that country by Keil Kraft Kits).

As is usual with kits of this type, items such as the engine, propeller, wheels, dope etc, are not included. Extra items required are noted on the adjoining Plan A and are available at your local model shop. For the strongest joints, use Regular Ambroid, the finest cement made.

The plans cover the R/C version (CG Electronics RX-1 receiver shown), but the free flight version (shown in construction photos) is basically similar, with the changes required detailed in the following instructions. For ease of handling, separate Plan A from this section by cutting along the vertical dotted line.

Only a few tools are needed for assembly - a balsa knife or single-edged rater blades, straight pins, fine sandpaper, brushes and finishing mat-erials. An old drawing board makes a fine working surface and the parts may be prevented from sticking to the plans by building over the top of transparent paper. Study the plans carefully before starting to build the model - and use pins to hold the various parts in position over the plans during assembly, wherever possible.

FUSELAGE: 1. Begin by cementing F4 to F9 former parts to-gether (a typical assembly being F7, F7-A and F7-1) flat over the former sections on Plan A. Cement F3-B pieces to front of F3-A(instrument panel) and join the F10 halves. Cement the plywood strips (landing gear guides) to F4 and F5 former assemblies - and drill holes for the landing gear retaining bolts through both formers and strips..."

Quote: "PIPER SUPER CRUISER IS SUPERSCALE KIT

Popular member of the Jetco line of Superscale kit models by CA Zaic Co, Inc. (Brooklyn, NY) is the Piper Super Cruiser. Billed as a 'Two-in-One' model, it is intended for free flight or radio control. Only concessions made when the original Piper factory plans were adopted for model use were a slight increase in tail surface area and wing dihedral.

Jetco expects many purchasers to enter competition with this Cruiser - AMA Free Flight Flying Scale and Radio Control Scale rules are included; also that real essential for competition judging, a three view!

An oldtimer feels a bit nostalgic opening this kit for one of the first sights is a tube of cement - Ambroid, at that. For those who don't go back too far in modeling, let it be explained that most early kits were 'wet' - they included both cement and dope. The latter was a problem, as it sometimes had dried up or leaked out by the time you opened the box. Cement has not been put in balsa kits for years; maybe Jetco is restarting a trend!

The Piper PA-12 has a 40" span and 231 sq. in. of wing area; fuselage length is 26". Total model weight as a free fighter is 11 oz. Obviously construction is quite light, as it has to be for good performance. If you keep the weight down you can fly the model with a Cox .020 or Herkimer .024 Cub engine. Otherwise any of the K&B Sky Fury engines from .049 to .074 are recommended. Plans show both inverted and upright mounting; former is more scale-like with e-gine completely out of sight.

The fuselage is the open-frame type, constructed by assembling two lower side frames, then joining these with built-up formers. The portion from nose to windshield is planked for appearance and strength. A plastic cowl nose dresses up this area. Landing gear wires are pre-bent; gear attaches by small metal clips and machine screws.

The hardware envelope, very complete, contains screws and nuts, washers, eyelets. On the plan is a listing of parts needed to finish the model - engine, wheels, fuel tank, dopes, and the like.

The wing is built in conventional manner with two main panels and a center section, assembled with dihedral. Internal rubber wing hold-down method enhances the scale appearance. This wouldn't be a true Piper without wing struts and a neat method has also been worked out for fastening these, making it easy for them to pop off in a hard landing. The struts contribute support to the wings, too.

This is a Bill Dean design; large plans by Dean and Gerald Zeigenfuse include 2-views (front and side) of pilot and passenger, for those who want full realism. A large decal sheet carries wing and rudder license numerals, an instrument panel and tiny Piper placards.

Tail surfaces are built up. Instructions caution the flier to make balance adjustments by slight front or rear packing under the stab—not by wing incidence changes.

To keep weight down and make a very simple radio installation, the plans show use of the F 8s M Electronics (formerly CG) Jupiter (also called RX-1) which is a receiver-battery holder-escapement in one compact package. This mounts on bearers directly under the wing opening, with on-off switch accessible from fuselage underside. The rudder is driven by a torque rod; escapement rubber is reached from rear of fuselage."

Does look to be a direct copy of the same designer’s model for Keil Kraft. I wonder what Eddie Keil felt about it, or did he even know?
Richard Falconer - 24/01/2024
It's interesting to compare this with the British KK offering. A few minor improvements, especially the sheeted LE. The most useful mod. is to fix the centre section and attach the wings via stub dowels and a band across inside. What you won't see in the UK is a glow engine sticking out the top! It doesn't need that much dihedral and this one [main pic, 011, 012] weighs 9oz. Flies a dream.

Oh that's very nice. Is that James Stewart in the cockpit? Very nice work.
SteveWMD - 31/01/2024
Well-spotted! See if you can identify the pilot in the smaller Piper that's should be up soon

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.
