Kits YOU Build!

Engine Adapters

Engine adapters are used to fly a smaller diameter engine in a model that has a larger size mount. The ASP 13/18 and 18/24 kits require construction and come with quick-change engine hooks.
The ASP 24/29 and 29/38 adapters are designed for friction fitting and require only very minor construction.
The Estes adapters are plastic and fit around the smaller size engines.

Testimonials

I must say that I was very impressed with the WAC Corporal kit I bought from you guys.  The quality of the components, particularly the recovery system, was so much higher than Estes. I had built that rocket when I was a kid, back in 1968, from an Estes kit, and still love the rocket.  Yours is so much better:  the kevlar cord, the way it is attached, and the shock cord are so much better, as is the nose cone.I will be buying other of your scale kits because of this.  I don’t think you do enough to tout the higher quality components.
Thanks for everything. - George P.
