Others favor a thin film of 5-minute epoxy. The problem with both of these choices is that they cure much harder than the surrounding foam. This creates a stress concentration that actually weakens the assembly.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">Recognizing these shortcomings, Eddie Noble of Nikitas Aircraft approached some industrial chemists and came up with a solution. Foamhesive is a fast-acting contact adhesive that was specifically formulated for use with Depron foam. Foamhesive joints remain flexible and strong. The new adhesive allows stresses to be transferred across the joints, rather than focussing the energy into, and breaking down, the foam beside the glue.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">Though not as fast as CA and kicker, you can build stronger and quite rapidly with Foamhesive. It is also much faster and neater than working with epoxy. Simply spread a thin film on each side of the joint, let it air dry for about a minute, then press the parts together. Foamhesive is relatively light, and any slop can be rolled of the foam and your hands for quick clean up. Foamhesive has become my favorite choice for foam models and is available exclusively from Billy Hell RC." Charming name.

The great thing about Foamhesive is that the drying time is short. Foamhesive creates a bond that is flexible and NOT stiff. This creates a joint that is much stronger than one created by foam safe CA.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">To use Foamhesive all you have to is run a bead of glue on one side of your two parts, adhere both pieces together and then separate. This activates the glue. Let your parts stand for 10 to 30 seconds then join the parts together. Glue will instantly join parts together.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">The trick to wrapping carbon fiber around a tapered leading edge is: Apply glue to the leading edge, apply the carbon fiber to the piece with glue and then pull it apart. Let the two pieces set 15 or 20 seconds. The final step is to apply the carbon fiber to one side first and tape, then the middle and tape, and then the other side and tape. Leave the tape in place.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">You can sand Foamhesive to a degree but it will gum your sandpaper since it is a rubber based compound.
