This is where adding that forth centering comes into play as I have it epoxied on the motor tube so when epoxying in the double wall coupler it sticks out of the booster exactly four inches. I then cut the slots on the booster tube all the way to the end so I could slide the fin can assembly in. Using the provided couplers I made a double wall coupler for connecting the booster to the booster extension. This also meant ditching the baffle as well. On the booster section I ditched the short 14 inch long motor tube and stepped up to a 28 inch long motor tube so it would extend into the booster extension tube.

I really like this LOC-N-Ring system as it takes out any guess work if your fins are perfect aligned and straight. With the way this kit is designed using the LOC-N-Ring system is best to build the fin can assembly outside of the rocket and then slide it into the booster tube. This rocket kit doesn’t include any instructions which I’m personally 100% okay with. A few modifications I did to kit was I added a 4 inch LOC electronics pay, put in a 28 long 54mm motor tube, forth centering, 100’ drogue tether, 12” X-form drogue parachute, 60’ main tether, 90’ X-Form main parachute. Whats in the box? In the box there are three 23 inch long body tube sections (booster, booster extension, and payload section), two couplers, baffle system (two bulkheads, two 4” long 38mm tubes, and coupler), three centerings (using the LOC-N-Ring System), a 14 inch 54mm motor tube, four main fins, four canard fins, a nylon strap shock cord with sewn loops, 4” bulkhead, a 50 inch main parachute, decals, and other miscellaneous hardware (rail buttons, I-bolts, z-clips motor retention set, etc.). This rocket kits comes very well packaged in a box and not in a standard plastic bag with a header card.

This rocket is a great overall sports flier or perfect for an L2 certification attempt. This is a scale model sport rocket kit of the AIM-120 Advanced Medium-Range Air-To-Air Missile, or AMRAAM.
