Hangar 9 UltraCote 10 Meter, Orange

Summary

 



Surface Preparation:
The covering job can just be as good as the surface of the surface it's applied over. In order for the covering to correctly comply with a surface area, the surface must initially|initially} be smooth and clean. Sand the model using a sanding block and progressively finer sandpaper, with the last sanding being made with 320 grit paper. Vacuum away all the dust, as specks of dust under the covering will leave unsightly bumps. Fill gaps and damages with a top quality filler. If using light-colored UltraCote® (such as white or yellow), utilize a tan-colored filler that matches the wood color to avoid|avoid} the filler from revealing|revealing} through.

Pro Pointer - Some expert builders “raise the grain” then sand a second time with 320 or 400 grit paper for the supreme surface. After the model is sanded, utilize a damp cloth to wipe down the model. Some modelers prefer to utilize a fine-mist squirt bottle filled with water to moisten the surfaces to be covered. As the surface dries, imbedded wood fibers in the surface will “stand up.” When dry, sand the surfaces once again using 320 or 400 grit paper. Raising the grain now and sanding it off will prevent the grain from raising later on under the covering, producing a rough surface. Vacuum the model completely and avoid touching the model with oily hands.Your model is now {ready|prepared|all set} for covering!



Trim Film 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. Eliminate the support (conserve for later on) and position the covering with the adhesive (dull) side down, focused over the wing. Set the covering iron to the application temperature of 220°F.

Pro Pointer - If the iron you're using does not display the actual temperature, here is a suggestion that will guarantee your iron is correctly set.Water boils at 212°F. Enable your iron to heat up at a medium setting. When the iron reaches its supported temperature, carefully pour a few drops of water on the iron's surface. Change the temperature till the water just begins to boil off. This approach is remarkably precise and is typically within 10° (of the exact 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 shown (an iron sock is highly recommened). Carefully pull the covering towards the root and towards the suggestion, as you work the iron from the center of the spar to the root and suggestion of the wing. Press gently with the iron, permitting the heat (not pressure) to activate the adhesive and bond the covering to the high point. Preferably, the covering will naturally lay flat against the whole surface 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 shown, using the iron at 220°F. If a wrinkle establishes, the covering can be carefully lifted and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar towards the routing edge, gently sliding the iron (set at 220°) towards the routing edge with the iron calling 2 ribs. Using your iron, adhere the covering to the remaining ribs, pursuing the suggestion and the root. Now finish the open structure leading edge, using the same approach. If the leading edge is sheeted, then follow the strategy noted 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, carefully cut the excess covering from the leading and routing edge, permitting 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 safely with the covering iron.


Wing Pointer:
Depending upon the quantity of the curvature of the wing suggestion, high heat (as much as 350°F) may be needed to diminish and stretch the covering to remove all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing suggestion while using heat with the iron. Remember, UltraCote® can be carefully lifted and rearranged to assist remove wrinkles. This feature is beneficial, especially when covering greatly curved wing suggestions. Continue working, pulling, and heating the covering around the suggestion till the covering is past the center of the suggestion. It may be needed to increase the temperature of the iron to accomplish higher shrinking to remove all wrinkles. Cut the excess covering using a #11 hobby knife, then reseal the covering on the wing tip.

Pro Pointer - If sealing the covering in tight locations such as corners or fillets, using the Wall mount 9 ProTrim Sealing Tool is extremely useful and leads to a professional surface.


Covering the Top of the Wing:
Using the support from the wing panel that you just covered as a design template, cut a piece of UltraCote® to be applied to the top of the wing. Make sure to cut a top panel, making sure that the adhesive is on the right side. Use the covering to the top of the wing using the same methods as described in actions 3 through 6. Make sure that the covering overlaps a minimum of a 1/4" when cutting the edges and safely seal the edges with the iron.


Shrinking the Covering:
Now it’s time to diminish the covering. With the iron set to 300°F, use heat using the same pattern utilized to use the covering starting at the spar and working outside. It may be needed to increase the temperature to 320°F to get rid of stubborn wrinkles. Utilize the minimum quantity of heat needed to tighten 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 Approach: 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 after heat is applied.


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

Important: Even if you're experienced in using other brands of covering, it’s important to read the following instructions. UltraCote® incorporates a unique multi temperature managed adhesive and shrinking system that makes accomplishing expert covering results easy.

Multi-Temperature Control System:
Comprehending the advantages of this system and the best ways to utilize it will make covering with UltraCote® simple and help to make sure expert results. When using UltraCote®, there are 3 crucial temperature levels to be conscious of.

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

Pro Pointer - Numerous expert builders mark this temperature on their covering iron with a marker or striping tape for fast referral, as this temperature is utilized regularly whenever placing on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® begins 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 made with the iron set at 300°F.
Maximum Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature above this point will not trigger further shrinking.

The rate of shrinkage is not directly in percentage to the temperature. The chart to the right shows how most of the shrinking rate occurs between 300°F and 330°F. At greater temperature levels UltraCote® continues to diminish however at a much slower rate. The smallest quantity of shrinking occurs between 340°F and 350°F. This is useful to remember when shrinking and tightening covering.


Important:As Soon As UltraCote® is shrunk to a particular temperature, a greater temperature must be utilized to further diminish the covering. For instance, if the covering was shrunk using 320°F and wrinkles start to appear/reappear, it will be needed to utilize over 320°F to accomplish further shrinkage.

Pro Pointer - Constantly utilize the minimum heat needed to remove wrinkles when tightening the covering, thus permitting a lot of shrinkage/temperature variety remaining if it's needed to further diminish the covering.



Useful Hints

Multiple Colors:
When using covering with a second 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 fulfill or at the edge of the covering, it is necessary 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 put over the iron is highly advised, as it typically avoids the surface of the iron from scratching. The sock soaks up heat and will require the user to work slower or to turn the heat up 10%. Nearly all expert builders utilize covering socks. Garage 9™ deals among the very best that includes muslin on one side to prevent heat damage and soft cotton on the other side for a soft, scratch-free finish.

Dryer is Much better:
Wood naturally soaks up moisture.Wood models actually grow and diminish somewhat throughout various seasons. This can be experienced by taking a trip from the humid Midwest of the United State to the dry deserts of Las Vegas. After a few days in the desert, the model establishes covering sags due to model shrinking. It is advise that you cover the model in a dry environment if possible. Putting the model in a room with a dehumidifier for a number of days before covering the model may prevent the covering from sagging due to model shrinkage.

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

Bubbles and Acnes:
Sometimes the extreme heat from the sun can trigger bubbles and acnes 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. Rapidly pop the bubble using a needle then wipe the area using a cold, wet wash cloth. The wet wash cloth quickly cools the area, permitting the covering to re-adhere. It may take a number of aim to completely remove the bubble/blemish, however this approach works great.

Clean Up:
The adhesive can be gotten rid of from the iron or model using acetone or a mild thinner.
