This is a futuristic kit with an unusually-shaped nose cone, forward-swept outer fins, and a ring fin.

The kit contains:

  • -Balsa nose cone
  • -body tube
  • -ring fin
  • -laser cut fins
  • -empty casing
  • -thrust ring
  • -engine hook
  • -retaining ring
  • -1/8" launch lug
  • -launch lugs for ion cannons
  • -wooden dowels for ion cannons
  • -elastic shock cords
  • -screw eye
  • -Kevlar® thread
  • -streamer
  • -tape disk for streamer attachment
  • -glue applicator
  • -templates
  • -decals

The instructions are well written and easy to follow with plenty of illustrations as with all Semroc kits. the body tube is minimum diameter so there in no motor mount to build you just tie the Kevlar® thread to a thrust ring and glue it in using the empty casing. I was surprised to get an engine hook, this is held on by an exterior ring. the three inner fins were filled and sanded then went on over the ring holding on the engine hook and were easily aligned using the included fin alignment jig. the three outer fins were also filled and sanded then glued onto the ring fin, the ion cannons were glued on to the tip of the fins.

I gave the rocket two coats of primer then pained it (except the nose) silver, I painted the nose white then masked off part and painted the rest silver. the fins were painted red, because I don't have orange.

Construction Rating: 4 out of 5

I flew this on an A8-3 and a B6-4, both flights were stable. The engine hook made prepping a lot easier. I planned to fly it on a C6-5 however it became to windy.

The supplied streamer was too small for this rocket so instead I used the 12" chute I got with my Javelin. this brought it down slowly and it suffered no damage on either flight.

Flight Rating: 4 out of 5

This is a very nice futuristic rocket that flies well. the only downside is the small streamer, the 12" chute works well for me.

Overall Rating: 4 out of 5
