Rounded, Like Laminar Flow……

The curvaceous Elipse 3.0 is 3" diameter rocket that stands 78” tall. Its shapely design sets it apart from the straight lines seen in other rockets. Notice the rounded, elliptical fins - -something extremely rare (and very difficult to do) with G-10 fins. These four shapely fins then flow graciously into a new rounded (Ogive) tailcone retainer - - the latest in our aluminum Slimline tailcone motor retainers. At the other end of this rocket is the sleek and rounded Pinnacle nosecone to balance the lines of this gorgeous kit.

Subtle, masculine and sexy, the curvilinear shape of the Elipse 3.0 is inspired by the famous Jaguar XKE.

Ok, this is seriously cool…The new Groove-Lok fin attachment system makes attaching your fins much more efficient. Made of extruded aluminum, the Groove-Lok holds your fins in preset channels that are perfectly aligned. It’s like having a fin-alignment guide built into the rocket.

Let’s face it; laying up fins the old way is like juggling eggs on the roof of a moving bus. You have to aim and drip epoxy down into an impossibly small space while keeping the fins straight and aligned, making sure the epoxy and cloth are making contact, while keeping the epoxy drips out of the motortube, off the airframe and away from your shoes. Fun, huh?

Now there’s a more efficient way - - the Groove-Lok. You epoxy the fins into the preformed channels that are the exact width of the G-10 fins. We’re in love with this product and you’re going to see it in more of our kits. To learn more about Groove-Lok, click here,
