About this Plan

Pelican. Free flight gas model.

Quote: "The Pelican, this month's gas buggy, is really one of the efficient, yet easy to build, Class A jobs ever to hop off a contest runway. Stressed to take any of the high powered class A engines, this 'modeler's dream' is a natural for those many spring and summer meets. The model from which this job is developed placed second in the Class A senior event at the '39 Nationals, and although the Pelican has not been entered in active competition, the hundreds of sport flights it has made during the last few months indicated that it should be watched in competitive flying - and not without field glasses, either!

Before attempting to build the Pelican, study the plans carefully and read these instructions two or three times. When you are fully acquainted with both, you may proceed with the fuselage construction.

FUSELAGE CONSTRUCTION: The side view of the fuselage should be scaled up to full size. Then the longerons and uprights, which are of medium weight balsa 3/16" square should be pinned inplace on the plan. The bottom longeruns are first soaked in water for a few minutes making it easier to bend them to the plan form. They will automatically hold their shape better when dry.

After the uprights are in place and the glue joints dry, the two sides of the fuselage may he removed from the plan and joined, using 3/16" square cross-pieces. The dimensions of these may be obtained from the top view of the fuselage plan. When finished, the cross-section of the fuselage at all stations should resemble a rectangle.

The fire wall of 1/16 hard sheet balsa is glued to the front of the fuselage frame. Slots are cut into this bulkhead to receive the motor mounts, The size of these basswood mounts given on the plan is for one specific motor and may be altered to fit various other motors. A good gluing job on the mounts is essential to prevent them from loosening because of motor vibration.

A hard piece of 3/16 sheet balsa is cut 'U' shaped and glued to the front ends of the motor mounts. A piece of 1/16 sheet balsa is glued to the bottom of the mounts and serves by catching the oil dripping from the motor. This whole front section is made oil proof by lacquering it several times.

The landing gear is bent from 1/16 steel wire, as shown, and lashed with strong thread to the two cross pieces. A few generous coats of glue are given both the thread bindings and the spots where the cross pieces join the fuselage sides.

The ignition system may now be installed. The wiring diagram shown should be followed carefully. Be sure to fasten securely the coil and the timer.

Detailed instructions for making the battery box are given on the drawings. When completed, batteries are inserted and then the box is so placed in the fuselage that the model balances. The box should be glued in the fuselage at this spot. Consider the model balanced when it rides on an even keel when suspended at a point on the wing 35% of the wing chord. This of course cannot be determined until the plane is completely finished and assembled. Therefore assemble the plane and leave the top of the fuselage uncovered. Then the battery box can be placed correctly without much trouble. The original model balanced with the battery box as shown on the plan.

The front section of the fuselage is covered with thin sheet balsa as indicated by the dotted lines on the plan. The completed fuselage is covered with gas model tissue and then given four coats of dope. The top of the fuselage, as explained before, remains uncovered until the battery box is installed. Then a small opening is left over the battery box to facilitate the changing of batteries.

WING CONSTRUCTION The wing is made in three sections. The center portion lies flat while the tips are raised to give the proper amount of dihedral. The required number of ribs are cut and slotted, and then glued onto the main spar at the points indicated on the plan..."

Hi Steve, Have a look at the Pelican plan and photo. I think this model should be 40in span and not 55in. Count the centre ribs of the wing using the photo. I may be wrong ?

Thanks Terry, I think you're right. Let's call it 40in wingpan - until we hear a better argument.

To understand this plan is fine, compare it with several of the web. You cannot base a shot on a photo.
Néstor Hugo Fiorini - 27/08/2019
Yes, but the plan is badly (misleadingly) drawn. It does not have a centre-line on the middle of the wing. So it is unclear that the wing has only 3 panels. That is why the photo is useful. To help understand. See my sketch with red corrections [morepics 004].

The plan is original and can be built like this, respecting that. Won't it be badly built? What is wrong with the photo model? It could have taken away the size of the wind.
Néstor Hugo Fiorini - 28/08/2019
Steve, the plan lacking a centre-line is as you rightly say misleadingly drawn. At those times there was a lot of misinformation flying around, so to speak, see for instance the B-29 fin in Bill Wylams Scale Aircraft Drawings vol. II in the RCLibrary, #RCL1390. The only things right in that drawing was that the B-29 had wings and four engines (of wrong shape at that). This was purposely done to to lead the enemy astray. In the case of the Pelican drawing dare I suggest it would be the same thing, no CL (no CG either, mind you) so whatever Hitlerjunger got hold of this plan by devious means would remain in doubt as to the true span of this fat-belly hippo of a model due to the plan ambiguities. The plan being American, I see the FBI's J.Edgar Hoover hand here.

The CofG is stated in the article as 35% wing chord. The depth of the fuselage is probably to comply with competition rules

Thank you for your clarifications, pmw, I hadn't noticed the CG location, and of course the Guppy Look was common in designs of the time, possibly rule mandated as you suggest.

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.
