General Assembly Instructions

Thank you, for purchasing this Stevens AeroModel Sky Scout™. A design inspired by the joy of flying. This model has been developed and manufactured using state of the art CAD/CAM systems and features a unique interlocking construction process that, when compared to traditional methods found in other model aircraft kits, save countless hours of measuring, cutting, sanding, and fitting. We are certain that you’ll find our kit to offer a truly exceptional build experience. As this kit is recommended for the novice model builder and “pilot”; we invite absolute beginners to correspond with us, or to seek the help of another seasoned builder. At any time should one run across a term or technique that is foreign please don’t hesitate to contact our staff with your questions.

READ THIS

Please READ and RE-READ these instructions along with any other included documentation prior to starting your build and or contacting our staff for builder support.

Pre-sanding

Do not skip this step. Prior to removing any parts from the laser cut sheet wood use a sanding block loaded with 250-400 grit paper and lightly sand the back side of each sheet of wood. This step removes any residue produced as a result of the laser cutting process and, as we have found that most stock wood sizes run several thousandths of an inch over sized, slightly reduces the thickness of each sheet.

Leave your pre-sanded parts in the sheet until required in the assembly process.

Protecting your worktable

Use the poly tube that this kit was shipped in as a non-stick barrier between your worktable and the product assembly. Promptly clean up any epoxy spills with rubbing alcohol and a disposable towel.

Bonding the assembly

As this product tabs, notches, and otherwise interlocks like a 3D puzzle we suggest that when fitting parts you dry fit (use no glue) the parts together first. It’s advised to work 1-2 steps ahead in the instructions using this dry-fit technique which allows ample opportunity to inspect the fit and location of assembled components and realizes a benefit as each successive part contributes to pulling the entire assembly square. Once you arrive at the end of a major assembly step(s) square your work on top of a flat building table and revisit the dry fit joints with glue. Using the dry-fit process you’ll be able to recover from a minor build mistake and will ultimately end up with a more square and true assembly.

Unless otherwise noted in the instructions, always use medium CA glue for bonding parts.

Never force the fit!

Remember this is a precision cut kit our machines cut to within 5 thousandth of an inch in accuracy. Yet the wood stock supplied by the mill may vary in thickness by up to 20 thousandths. This variance in the wood stock can cause some tabs/notches to fit very tight. With this in mind, should you find a joint or two to fit rather snug consider lightly sanding a tight fitting tab rather than crushing and forcing your parts together. You’ll break fewer parts in assembly and will end up with a more square and true assembly.

Scale Notes

The Pietenpol Sky Scout was designed by Bernard H. Pietenpol in the late 1920’s as an easy and inexpensive to construct homebuilt aircraft for the average guy. Plans were published in Modern Mechanics and Inventions in 1932, and reprinted in their annual Flying Manual in 1933, and are still available from the Pietenpol family. This model was designed using the original plans as published in the 1933 Flying Manual.

Since the Sky Scout depended on the builder’s ability to scrounge parts and materials, no two were built exactly the same. Variations in the type of engine, cowling, landing gear configuration, etc. were the norm.

We designed our model with simplified scale details, leaving plenty of room for variation and the taste of the individual modeler. Excellent scale detail reference material can be found in the afore mentioned 1933 Flying Manual, still published by the Experimental Aircraft Association, and on several sites on the internet, including the official Pietenpol site and many others dedicated to this particular aircraft.

Additional details you might want to add are: a shock strut or spreader bar for the landing gear, wood fairings for the landing gear struts, wire bracing between the flying and cabane struts, a pull-pull control system with scale control horns on the control surfaces, and cockpit coaming. Details specific to a particular aircraft, such as wheel type, engine and cowling, windshield, tail skid type, color scheme, etc. may also be added.

Have fun researching your model. Changes to the details should be planned before construction begins. Read this manual thoroughly before making any changes. Or simply build it as we represent it here and enjoy a simple build and many hours of pleasurable flying.

Build Instructions


Definitions of Construction Terminology:Fit - Assemble parts together “dry”, using no glue, as friction between the fit parts alone should retain the pieces within the assembly.

Tack / Tack Glue - Use medium CA glue administered sparingly through use of a fine gauge glue tip to place a small dot of glue to retain fit parts within assembly (non-permanent easily separated).

Bond - Unless otherwise specified, use thin or medium CA glue and a fine applicator tip to thoroughly glue parts within assembly along all mating surfaces.

Fillet - Use medium or thick CA glue administered through a fine to medium gauge glue tip to build up a trough of glue along adjoining parts. The easiest way to understand what a proper glue fillet looks like is to go and have a look at the caulk that seals your bathroom shower or tub to the walls and floor; your glue fillet should resemble this caulking. Fillets are typically used in high stress locations such as motor or landing gear assemblies.

Harden - When requested to harden a wooden part with glue we are suggesting that a thin viscosity CA glue is applied liberally to an area (usually a mounting hole for a screw, exit point for landing gear, or some other part that needs additional strength), allowed to wick into the fibers and pores of the material, and cure.

Proper Use of Thin, Medium, and Thick Cyanoacrylate (CA) Glue

Follow the general tips given below for determining the proper use of the various viscosities and varieties of CA glue as they relate to the construction of balsa and hardwood models. We suggest the use of a “Top Shelf” CA glue such as Zap brand glues as they have proven more consistent in formulation, working time, and strength than the wide array of budget glue products.

Thin - This watery form of CA glue readily wicks into porous materials (such as balsa or ply woods) and cures/sets rapidly (usually within 1-3 seconds of application). A fine gauge glue tip is mandatory in regulating the flow of this CA glue from bottle to model. Thin CA glue is excellent at rapidly bonding tight fitting joints and hardening areas of balsa wood. Thin CA glue is not suggested for bonding parts that have minor gaps or spans to bridge, wrapped parts (such as sheeting), or when additional working time is required. Generally an accelerator is not used with thin CA glue.

Medium - A general purpose glue with good gap filling properties, fair wicking ability, and intermediate working times (5-10 seconds). Medium CA glue is an excellent glue for temporarily bonding or tacking parts together, filling minor gaps, bonding plywoods, creating fillets, and reinforcing high stress areas of the model such as spars and motor mounts. A fine gauge applicator tip is recommended to precisely apply medium CA glue. Accelerators are typically not used with medium CA glue unless repairing a previously bonded joint.

Thick - Generally not required for construction of our model kits, thick CA glue gives the user extra working time (10-20 seconds) to properly locate and apply sheeting, build larger fillets, or fill large gaps. Accelerators are generally preferred when making repairs with thick CA glue.

Accelerator - Commonly referred to as “Kicker” and available in pump and aerosol configurations. Good for setting glue rapidly when making repairs or to decrease the working time of Medium and Thick CA’s. An accelerated glue joint is typically weaker than if the glue was left to cure normally.

Odorless / Foam Safe - Often available in Medium and Thick formulas, this glue sets very slowly and does not produce as many fumes when curing. Good for use in place of normal CA glue when the user is sensitive to the fumes or has a CA glue allergy. Accelerators are almost mandatory to decrease the working time of this product.

11/12/2011 Kit Update (Pre Cut Brass Hardware)

Please note that we have improved the wheel assembly of your Pietenpol Sky Scout kit by providing pre-cut and professionally de-burred brass hardware for the wheel axle, wheel bearing, and wheel collars. This update specifically affects assembly steps in the following section “Landing Gear”.

We have elected to leave the original instructions intact for those building from short kits or with older full kits that do not feature the new pre-cut hardware. I have indicated in the following steps where pre-cut tubing is provided and added a strikethrough to text that is no longer applicable for those builders using the new pre cut parts.

The new pre-cut hardware is described below and included in the amended parts list at the beginning of this manual:

2 - (.188) 3/16 in x (1.50) 1-1/2 in. Brass Tube (Axles) 2 - (.219) 7/32 in. x (1.25) 1-1/8 in. Brass Tube (Wheel Bearings)4 - (.219) 7/32 in. x (.156) 5/32 in. Brass Tube (Wheel Collars)

Build Instructions

Preflight to First Flight

This model is supplied with functional flying struts. Flight should never be attempted without struts properly installed to model.

Have and experienced pilot assist you with pre-flighting your new model. Just like having someone proof read something you’ve written, having a second fresh set of eyes to inspect your final product is often helpful at avoiding disaster.

While not an exhaustive pre-flight check these are some of the major items that you should consider using when developing your own pre-flight check list. Get in the habit of always pre-flighting your models before each and every flight.

☐ Weight and Balance - Check the Sky Scout’s center of gravity. The model should balance between 2-1/2 - 3 inches from the leading edge of the wing Use a permanent marker or trim tape to mark the underside of the left and right wing half at the forward and aft most CG measurements as given above.

Use your right and left hand index fingers and suspend the model from below, between the marked CG measurements. Site from profile of aircraft against horizon. If the shape stringer along fuselage side appears to hang level with horizon line, then the Sky Scout is

Build Instructions


Preflight (continued)

properly balanced to fly. Move equipment and or battery within fuselage to obtain proper balance.

☐ Check Weather - The Sky Scout’s first flight should be in zero wind conditions. The Sky Scout is capable of flying in winds up to 8-10 mph so long as the pilot is capable.

☐ Inspect airframe for warps and obvious signs of wear or damage. Do not fly a damaged or warped model.

☐ Inspect control surfaces for center, proper direction of travel, rate of throw, secure pushrod connections, hinges, and servo mounting hardware.

☐ Check wing attach points and struts for sound attachment, damage and/or wear.

☐ Check landing gear repair or replace wheels. Check that tires are properly retained.

☐ Inspect battery for full charge. Never begin a flight with a partially charged battery.

☐ Clear prop! Before applying power to the model, clear and keep clear of the prop arc. As electric motors are capable of inflicting severe damage (more so than their internal combustion counterparts) and may turn on unexpectedly anytime power is applied to the system. Respect the business end of the model (the prop and prop arc) treating every electric model and propeller as if it were a loaded gun.

☐ Range check radio. Follow the radio makers guidelines for performing a proper range check.

☐ Check for traffic. Proceed to the flight line (With your mentor/instructor if you are a novice pilot) and observe other RC traffic. If the runway is clear, and no one is in the pattern to land, loudly announce your intentions to take off. Remember all aircraft on ground must yield the runway to those landing.

☐ Go flying. Point model into wind (if present) and steadily advance throttle to full. Use rudder to correct track while on ground roll. Within several feet the model should be airborne. Fly model to comfortable 1-2

mistake high altitude, reduce throttle to stop climb, then trim model for straight and level f l ight at a comfortable cruise speed (Depending on speed control responsiveness Sky Scout typically cruise at just over 1/2 throttle).

☐ Setup for landing. Clearly announce your intention to land. Make landings into the wind. With rudder/elevator control and no ailerons setting up landings in cross-winds should be avoided until you are comfortable with the model’s in-flight behavior.

☐ You’ve completed your first flight(s). Sky Scout should have only required a click or two of trim to obtain level flight and should perform smoothy in both pitch and roll.

By now you’ll have noticed that the Sky Scout is a very stable airplane. When built straight, and trimmed for level flight, the Sky Scout should gently return to wings level from any attitude. We’ve found the Sky Scout to capture the imagination of prospective pilots both young and old.

If your first flight was a bit more exciting than you’d have liked and are having problems with erratic flight performance; please inspect your equipment and airframe for damage, improper installation, and/or twists and warps. The most common mistake is to try and fly with a warped or twisted wing. Make certain that your wing is straight before you fly.

Have fun learning the ins and outs of the Sky Scout in-flight performance and feel free to share your thoughts and experiences with our staff. We are committed to improving your build and flying experience and are constantly refining our processes, designs, and manuals to reflect customer feedback.
