HAND-CRANK SPEED WINDERS 
      Our Speed Winders make winding rubber motors on our airplanes fast and easy. These labor saving tools wind 5, 10, or 15 revolutions on the motor for every 1 handcranked turn.  Requires 3 hands (i.e., you need a partner to hold the model). 
To use, unhook the motor from the rear motor hook, 

     stretch the motor, and walk in toward the plane while winding, then re-attach the motor.
     The 5:1 Winder works with all our rubber-powered planes, including ready-to-fly, as long as rubber motor can easily be unhooked from its rear attachment and re-attached. (e.g., not the Flyboy). The 5:1 is not a good choice for the Cruiser or Sorcerer (too slow), and will not work with the Guillows Flyboy. We have reduced the price on the 5:1 winder from $7.50.  

     Use our 15:1 and new 10:1 Rubber Winders for no-fuss, no-nonsense fast winding for competition events. These are absolutely necessary for the Cruiser or Sorcerer models (they require 1500 - 2000 winds). You cannot hand-wind these models, and the 5:1 is too slow.  
We have reduced the prices on these high-speed winders from $25.95.

     The new 10:1 winder is a little slower than the 15:1, but the 10 to 1 ratio allows easy and intuitive counting of winds - so important in contest flying!  The 15:1 winder is the fastest simple hand-crank model available. The 10:1 and 15:1 are not recommended for the Guillow kits (Build-n-Fly,Ready-to-Fly).

Electric Winder operates on 2 AA batteries. Resettable counter lets you count winds, so you know exactly when to stop winding. An efficient labor-saver for all our "Just-for-Fun" models (not for the Sorcerer or Cruiser). This is the only winder you can use with the Flyboy. Not usable for the Sorcerer or Leading Edge or any other competition model.

   Builders' Supplies:   Glue, Assembly Pins, Mylar, knives, single-edge blades, precision jig cutters 

Grip Pins  - a real necessity!  More expensive than T-pins but sharper and much easier to use.
   These make the job easier, produce better quality work. Two structure sides can be duplicated, one one top of the other with wax paper in between, for symmetric structure precision. Also provides light clamping pressure for setting glue joints at any angle. Use the pin shoulders to hold the work, or pin through a piece of scrap used to press the work to the workboard.  Gentle side pressure can be applied to keep joints in place while drying, and cambered ribs can be held vertical with 1 or 2 pins on each side of the rib. Note: Use very light pressure on balsa parts and do not pin through balsa on Cruiser or Sorcerer models!  
   We suggest using an accurately flat, sufficiently large, soft balsa or pine board or piece of 3/4" softwood plywood, clean, flat heavyweight corrugated boxboard, 2'x2' ceiling tile, or dense insulation foam board as a construction surface for use with these pins. Cover work surface with wax paper to permit easy removal of finished assemblies. 
#587 - Grip Pins . . . . . . . . . . . . .$6.50   (Box of 50 pins)      

Ambroid Cement
The choice of many experts. It is very forgiving, does not require joint pressure, and can be removed from an incorrectly built joint with acetone. Apply sparingly with toothpick or balsa sliver. Where weight is critical, do not follow tube directions; apply to one part only.  Where strength is more important, apply to both parts, rub into wood and remove excess, allow to dry a few minutes, then reapply to one part and mate surfaces. Hold in place until dry with gentle pressure with pins. (NOT SOLD SEPARATELY) 

G18AMBR  1.8 oz tube Ambroid Cement . . . . . . . . . . . . . . . . . $3.25    
 WE MAY SHIP EITHER DUCO OR AMBROID IN PLACE OF THE OTHER, DEPENDING ON WHAT IS IN STOCK. 
Right now, what we have is Ambroid Cement.  We were lucky to get it.

We also recommend a similar cellulosic solvent-based glue, that old standby Duco Cement.
This is the same strong, reliable glue we were building models with 50 years ago. It's a little thicker than Ambroid, and can be cut with a small amount of acetone to adjust viscosity for lightweight structures such as airplanes.
(NOT SOLD SEPARATELY)  At present, we do not have Duco Cement. 

G62455DUC  DUCO CEMENT 1.0 oz  -- $3.25 --  OUT OF STOCK

Mylar Film
Use this in place of tissue where performance is critical.
Paper-based tissue absorbs atmospheric moisture, and your wings, stab, and fin can be warped by changes in humidity.
We now offer 1.4µ Mylar film in rolls 12.5” x 10’, enough for covering several models.  It is superior to tissue in several ways.  It is included with the Cruiser kits, and may be purchased separately for the Sorcerers. We include updated instructions for use.  Application takes some practice, but it is worth the effort.

Aero-Gloss Clear Brushing Lacquer

Use this clear finish to fill and seal wood surfaces that will not be covered by tissue. Allow 24 hours to dry, sand lightly with fine sandpaper to produce smooth surface, then paint.  (You can't sand tissue covering!)  May be used over Testors paint (see below) to add luster and depth to colors.   Also apply to tissue covering to tighten and strengthen, and to provide a better base for painting.  1 ounce (29.5 ml) bottle is enough to do one large or several small models. NOT RECOMMENDED FOR COMPETITION - ADDS TOO MUCH WEIGHT.

1-OZ. SIZE IS NOT AVAILABLE SEPARATELY - SOLD ONLY WITH ONE OR MORE MODEL AIRPLANE KITS.   Flammable. Contains organic solvents. Not recommended for children younger than 8 years old.

Replacement Parts
   
Replacement Rubber Motors & Motor Supplies
Our #376, #377, and #378 48-foot rubber motor thread is now genuine high-performance Tan Super-Sport Rubber, with the highest energy return of any rubber motor. 
***If you are using our #376, 377, or 378 motors for high-performance competitive models like the Leading Edge, you MUST use O-rings and Lube, both sold below.

Care and selection of Rubber Motors:
1. For longest life and maximum performance, lubricate the rubber motors with Sil-Slick, available below.  Store motors in marked Zip-Lock Bags. Use Speedwinders for proper stretch-winding (directions in model kit package), and always count winds. Do not use an electric winder!! Select motor according to weight specs and energy requirements, model weight and room dimensions, among other things.
 The selection of a motor, and determination of length, is dependent in part on the ceiling height of the competition venue and the prop pitch angle.  You need enough torque to get the plane up to the ceiling in a steady, gradual climb. The torque curve at that height should yield just enough to start the plane flying level, after which it descends under power.  Also, the greater the prop pitch angle, the more torque you need.  High ceiling, steep prop pitch indicates more rubber mass.  A thinner rubber gets more winds and a shallow prop pitch, spins faster.  A thinner rubber may not provide the power needed for climbing.  Experiment!  There is no straightforward formula for calculating this.  Another variable is number of winds. Use #377 (3/32") for Leading Edge or Sorcerer. 
WINDING A RUBBER MOTOR FOR COMPETITION FLYING: (Also see Last year’s Cruiser directions)
Important: You MUST attach an O-ring (SOLD BELOW) to the tail end of the motor to facilitate removing and replacing the motor from the motor hook for winding. 
*Have an assistant hold the front of the model by pinching the nose of the model and the propeller hub with the thumb and forefinger of the left hand.
*With the one hand, the assistant places a cardboard sheet between the motor to be wound and the model. This will protect the model in the event that the motor becomes loose or breaks during the winding procedure. NOTE: Should the motor snap back to the assistant's hand, the assistant must insure that the model is not dropped or released. THE ASSISTANT’S JOB IS VERY IMPORTANT IN CONTRIBUTING TO THE SUCCESS OF THE TEAM.
*The motor must be stretched out approximately 8 times its normal length (6 to 7 ft) and should be at a 10-30 degree angle away from the plane’s motor stick.
*Begin turning the crank handle in a clockwise motion to wind the motor. For the first few flights put in approximately 300 turns into the rubber motor (divide the motor turns by the gear ratio to arrive at the number of crank handle turns). After the first flight is completed, and adjustments are made, add an additional 100 turns into the motor. As the last of the 100 turns are finished, the person winding the motor should slowly walk toward the rear motor hook so that the rear o-ring is at the rear motor hook at the completion of the winding process. THE ASSISTANT NEEDS TO BE SURE THAT THE O-RING IS SECURELY IN PLACE ON THE REAR HOOK PRIOR TO RELEASING IT FROM THEIR CONTROL. FAILURE TO EXERCISE DUE CARE COULD RESULT IN A DESTROYED MODEL.

NSSLO4:  SIL-SLICK RUBBER LUBE 2 OZ  --  $3.25   --   Quantity  
Silicone oil, a step or two up from Armorall (at auto parts store). You must lubricate rubber motors to get their full power, and keep them from breaking when fully wound. Sil-Slick is seriously greasy stuff! Consider wearing disposable latex gloves when lubricating motors. Put some Sil-Slick in a zip-lock poly bag with your cut-to-length motor and let it soak. Put on the O-ring and tie the knot BEFORE lubricating!

IKARA Propellers  
These are not the common "Ikara" props available elsewhere.  These super-light props are designed specifically for endurance flying models.  They have the most efficient configuration of camber and hub-pitch, 

9.5" Ikara prop - included with Leading Edge Kit
are made of a paper-thin plastic which can easily be re-pitched or re-shaped with sharp scissors to provide maximum performance while complying with competition rules or torque requirements. 
     The thin plastic blades flex slightly to achieve a steeper pitch at the beginning of the flight to slow down the climb, 
but then flex back to the original flatter pitch for the remainder of the flight, thereby making somewhat of a variable pitched prop. Note: These props require skill and care for proper shaping and tuning. DO NOT USE WITH ELECTRIC WINDER!

New for 2008: Our new Ikara props are pre-assembled with hub, bearing, and motor hook, for rapid replacement in the event of prop damage. 
Strongly recomended:
Install a 1/8" Teflon washer on prop shaft - 
reduces friction, greatly enhances efficiency. Included at no charge with purchase of propellers, or available in bag of 6 washers. 
Installation requires dis-assembling prop.

     The "COMPLETE PACKAGE" includes 2 pre-assembled Ikara propellers, with prop hanger and rear motor hook for each propeller, and 2 Teflon washers.  The propeller bearing plugs into a mating hole in the hanger, so a new prop can be swapped with a damaged one in seconds. BUY THIS ITEM FOR NEW CONSTRUCTION. 

     The "REPLACEMENT PACKAGE" includes 2 pre-assembled Ikara propellers, and 2 Teflon washers. Use these to replace damaged props. BUY THIS ITEM TO REPLACE BROKEN PROPS ON ALREADY-BUILT MODELS.

Scales

AMW-55 electronic digital pocket scale. 55g capacity, .01g resolution   New for 2008! 

     The AMW-55 is a super-sensitive small scale that lets you weigh each component, each stick, so you can keep track of weight as you are building your model plane or bridge, and modify the parts before you install them. Repeatability is excellent: we found it to be within .03 g maximum across a small sampling of our first shipment. Accuracy seems excellent, too: We measured the weight of a paper clip on 4 scales at .44, .43, .44, and .45 g. Weight of a 50g test weight was also within .04g on each of several tested scales.
This new product looks like an amazing value. Time, experience, and your feedback will tell!

The AMW-55 is so sensitive
that gently breathing on it from a distance of a foot will change the reading! 
** Handle this extremely delicate device with great care.
** Do not expose to moisture, deceleration shock or impact, heat or cold.
** Do not exceed 55g weight capacity.  This scale is best for weighing objects less than 40g.
** For most repeatable and accurate results, make all measurements at same ambient temperature, in room without air currents, on stable, flat, horizontal vibration-free surface. 
** Read product directions carefully before using.

AMW-55 Specifications:
*Scale is built in to a hardshell case measuring 5" x 3" .75" closed. 
*Power: 2 AAA batteries (included)

  *Auto Shutoff after approx. 1 minute inactivity.
  *Weight platform: 2.5" x 3"
  *Functions/controls: On-off, Tare, Mode (g, oz, gn, ct)
  *10-year limited warrantee
