HIGH HEAT FORMULA!

...Locks fins into place!

We discovered expandable foam years back from a group of level-2 and -3 flyers in California. It¹s a two-part urethane, closed-cell expandable foam that fills in the fin tab / motor tube area, nosecone, or anything else you can think of. We've used it to reinforce a crimped airframe. Easy to use; Just mix the two-part foam and pour into the cavity. It starts to expand in less than a minute. It¹s high-density structure helps hold fins into place, and provides rigidity to other structures like nosecones, with virtually no cost in weight. The foam does not require oxygen to cure. Both this and the MEGA-FOAM below are special heat-resistant formulations. Expands approximately 20 to 30 times it's size. The 16 oz NHP foam is an excellent shop-grade foam for small projects. For premium grade foam with a volume savings, see the 2- quart MEGA-FOAM below.

Two parts 16 oz total...... $23.95

Mega-Foam

Save 33%!

2 Quart Kit....$39.99

(you'd pay $60 for this much of the smaller-quantity foam above)

$41.24

a premium foam at a volume discount

Not only a better value than the foam above, we think it's a higher grade as well.
The NHP foam above great, but for those who need the best, MEGA-FOAM is it.
It has excellent pour & mix characteristics. Sets up well - - very uniform.
It has a VERY long shelf life too, just like Epoxy.

It's the best foam we carry….period.


SMALL REMOVABLE RIVET

The Small Removable Rivet is designed for assemblies requiring fast and economical fasteners that can be installed without tools. The 2 Piece Molded Fastener comes assembled ready for use. The Rivet is placed in the hole and the smooth, oversized head is pressed. The specially designed legs expand and firmly lock the components permanently in place. To remove, use a screw driver to pop it back up. Very handy for securing nosecones to bodytubes or other applications. Eliminates screws and wood backing.

LARGE REMOVABLE RIVET

Removable Rivets are two-piece nylon rivets which can be removed by retracting the pin, and then the body. The body incorporates a slot in line with the pin so that the pin can be removed by inserting a small screw driver, other sharp edge, or even a fingernail underneath the head of the pin. In addition to working in a .250 round hole, will also fit the .210"/.218" square hole found in the "darling" type shelf commonly found in retail stores. Very handy for securing nosecones to bodytubes or other applications. Eliminates screws and wood backing.
