Hangar 9 UltraCote 10 Meter, Orange

Introduction

 



Surface Preparation:
The covering job can just be as good as the finish of the surface area it's used|used} over. In order for the covering to appropriately adhere to a surface area, the surface area should {first|initially} be smooth and tidy. Sand the model using a sanding block and gradually finer sandpaper, with the final sanding being finished with 320 grit paper. Vacuum away all the dust, as specks of dust under the covering will leave unattractive bumps. Fill spaces and damages with a premium filler. If using light-colored UltraCote® (such as white or yellow), use a tan-colored filler that matches the wood color to avoid|avoid} the filler from revealing|revealing} through.

Pro Pointer - Some expert home builders “raise the grain” then sand a 2nd time with 320 or 400 grit paper for the ultimate finish. After the model is sanded, use a wet fabric to wipe down the model. Some modelers prefer to use a fine-mist squirt bottle filled with water to dampen the surfaces to be covered. As the surface area dries, inserted wood fibers in the surface area will “stand.” When dry, sand the surfaces again using 320 or 400 grit paper. Raising the grain now and sanding it off will prevent the grain from raising later under the covering, creating a rough finish. Vacuum the model thoroughly and prevent touching the model with oily hands.Your model is now {ready|prepared|all set} for covering!



Trim Movie to Size:
Start by covering the bottom of one wing half. Using scissors or sharp hobby knife, cut a piece of UltraCote® a few inches bigger than needed to cover the wing. Get rid of the backing (save for later) and place the covering with the adhesive (dull) side down, centered over the wing. Set the covering iron to the application temperature level|temperature level} of 220°F.

Pro Pointer - If the iron you're using does not display the real temperature, here is a pointer that will ensure your iron is appropriately set.Water boils at 212°F. Enable your iron to heat up at a medium setting. When the iron reaches its supported temperature, thoroughly pour a few drops of water on the iron's surface area. Adjust the temperature up until the water just starts to boil off. This method is remarkably precise and is usually within 10° (of the specific application temperature of 220).


Tacking Covering to Spar:
Tack the covering to the spar or the high point of the wing, using your iron as revealed (an iron sock is extremely recommened). Carefully pull the covering towards the root and towards the pointer, as you work the iron from the center of the spar to the root and pointer of the wing. Press gently with the iron, allowing the heat (not pressure) to activate the adhesive and bond the covering to the high point. Ideally, the covering will naturally lay flat against the whole surface area with a minimum of wrinkles.


Covering a Solid-Sheeted Wing:
If covering a solid-sheeted wing, work from the center of the spar outside to the routing edge then to the leading edge as revealed, using the iron at 220°F. If a wrinkle develops, the covering can be thoroughly raised and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar towards the routing edge, gently moving the iron (set at 220°) towards the routing edge with the iron contacting 2 ribs. Using your iron, adhere the covering to the remaining ribs, working toward the pointer and the root. Now finish the open structure leading edge, using the very same method. If the leading edge is sheeted, then follow the strategy listed above under “Covering a Solid-Sheeted Wing.”


Sealing the Edges:
With the iron set to 220°F, seal the leading and routing edges. Using a straight edge and a sharp #11 hobby knife, thoroughly cut the excess covering from the leading and routing edge, allowing a minimum of a 1/4" overlap to twist around the leading and routing edge of the wing. Now seal the leading and routing edges firmly with the covering iron.


Wing Pointer:
Depending upon the amount of the curvature of the wing pointer, high heat (approximately 350°F) might be needed to diminish and stretch the covering to eliminate all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing pointer while applying heat with the iron. Remember, UltraCote® can be thoroughly raised and rearranged to assist eliminate wrinkles. This feature is beneficial, especially when covering dramatically curved wing ideas. Continue working, pulling, and warming the covering around the pointer up until the covering is past the center of the pointer. It might be needed to increase the temperature of the iron to achieve greater shrinkage to eliminate all wrinkles. Trim the excess covering using a #11 hobby knife, then reseal the covering on the wing tip.

Pro Pointer - If sealing the covering in tight areas such as corners or fillets, using the Wall mount 9 ProTrim Sealing Tool is extremely helpful and leads to an expert finish.


Covering the Top of the Wing:
Using the backing from the wing panel that you just covered as a template, cut a piece of UltraCote® to be applied to the top of the wing. Make sure to cut a leading panel, ensuring that the adhesive is on the correct side. Apply the covering to the top of the wing using the very same strategies as explained in steps 3 through 6. Make sure that the covering overlaps a minimum of a 1/4" when trimming the edges and firmly seal the edges with the iron.


Shrinking the Covering:
Now it’s time to diminish the covering. With the iron set to 300°F, apply heat using the very same pattern utilized to apply the covering starting at the spar and working outside. It might be needed to increase the temperature to 320°F to get rid of persistent wrinkles. Utilize the minimum amount of heat needed to tighten up the covering.

Pro Pointer - Usage heat, not pressure, to diminish the covering taught. If pressure is applied, gouges can be pushed into the wood. Let heat, not pressure, do the work.
Alternate Technique: A heat gun can likewise be utilized to diminish the covering. This works especially well over an open structure. It can likewise be utilized over a strong structure if a Hanger 9 Covering Glove™ is utilized to gently push the covering to the surface area after heat is applied.


Covering Fuselages and Other Solid Surfaces:
The strategy for covering fuselages and other easy flat surfaces is identical to covering a strong wing. Start with the bottom, then sides, and finally the top. Initially, tack the center of the surface area down using an iron set to 220°F.Work outside from the center, bonding the covering to the surface area. Trim and seal the edges. About 1/4" or more overlap is advised when applying the next piece of covering. Diminish the covering, using the very same method as explained above.

Important: Even if you're experienced in applying other brands of covering, it’s important to read the following directions. UltraCote® integrates a unique multi temperature controlled adhesive and shrinkage system that makes achieving expert covering results easy.

Multi-Temperature Control System:
Understanding the benefits of this system and ways to use it will make covering with UltraCote® easy and assist to guarantee expert results. When using UltraCote®, there are 3 crucial temperature levels to be aware of.

Application Tempature-220°F (100°C):
At 220°, the adhesive on UltraCote® ends up being active, allowing the covering to be connected to the model.While 220° will totally bond the covering to the model, it is well listed below the temperature that causes UltraCote® to diminish. This is precisely what's needed when very first connecting covering to the model to prevent the covering from distorting.

Pro Pointer - Lots of expert home builders mark this temperature on their covering iron with a marker or striping tape for quick referral, as this temperature is utilized frequently whenever putting on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® starts to diminish. This is called the Shrink On-Set point. After the covering is attached using an iron set to 220°F, the next action is to diminish the covering. This initial shrinking is finished with the iron set at 300°F.
Maximum Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum diminishing point. Raising the temperature above this point will not cause additional shrinkage.

The rate of shrinkage is not directly in percentage to the temperature. The chart to the right demonstrates how most of the shrinkage rate occurs in between 300°F and 330°F. At greater temperature levels UltraCote® continues to diminish however at a much slower rate. The tiniest amount of shrinkage occurs in between 340°F and 350°F. This is helpful to bear in mind when diminishing and tightening up covering.


Essential:As Soon As UltraCote® is shrunk to a specific temperature, a greater temperature should be utilized to additional diminish the covering. For instance, if the covering was shrunk using 320°F and wrinkles begin to appear/reappear, it will be needed to use over 320°F to achieve additional shrinkage.

Pro Pointer - Constantly use the minimum heat needed to remove wrinkles when tightening up the covering, therefore allowing plenty of shrinkage/temperature range remaining if it's needed to additional diminish the covering.



Useful Tips

Several Colors:
When applying covering with a 2nd color, it’s important that the light color be applied first (under the dark color) to prevent the dark color from showing through. Where colors satisfy or at the edge of the covering, it is important to not overheat this area (over 300°F), as this will diminish and misshape the straight edge.

Use a Sealing Iron Sock:
A covering sock placed over the iron is extremely advised, as it usually avoids the surface area of the iron from scratching. The sock absorbs heat and will require the user to work slower or to turn the heat up 10%. Almost all expert home builders use covering socks. Hangar 9™ deals among the best that features muslin on one side to prevent heat damage and soft cotton on the opposite for a soft, scratch-free finish.

Dryer is Much better:
Wood naturally absorbs moisture.Wood models in fact grow and diminish a little throughout different seasons. This can be experienced by traveling from the humid Midwest of the United State to the dry deserts of Las Vegas. After a few days in the desert, the model develops covering droops due to model shrinkage. It is suggest that you cover the model in a dry climate if possible. Placing the model in a room with a dehumidifier for several days prior to covering the model might prevent the covering from drooping due to model shrinkage.

Painting:
UltraCote® will accept most types of polyurethane, epoxy, and vehicle acrylic paints. It’s advised that the surface area be scuffed with 000 steel wool or Scotch® intense pads then thoroughly cleaned with acetone or thinner prior to painting. Model Dope or butyrate-based paint are not compatible with UltraCote®.

Bubbles and Imperfections:
Periodically the intense heat from the sun can cause bubbles and blemishes in the covering, especially when using dark colors. To remove these, heat the bubbled area using a heat gun to expand the air under the covering, causing the bubble to rise. Quickly pop the bubble using a needle then wipe the area using a cold, wet wash fabric. The wet wash fabric rapidly cools the area, allowing the covering to re-adhere. It might take several aim to entirely remove the bubble/blemish, however this method works great.

Clean Up:
The adhesive can be eliminated from the iron or model using acetone or a moderate thinner.
