  1. Big Fun!

    Posted by Andrew K. on 3rd Sep 2016

    When you want a break from your big complicated rocket or if you are new to high power, this kit is for you. It is a fun simple build and looks impressive when done. Does very well on 29mm high power loads. IMO, it looks much better with the longer cone though. The only thing I would suggest is adding a third centering ring to the kit and make the motor tube longer to shift your cg forward. The third ring let's one be able to do internal fillets which is a must with below bottom fins! SUPER KIT and so much fun to fly! I could not wait to fly it when I built it, so i went out to launch it when it was still in primer, a first for me! A 5.5 inch version would be glorious!

  2. Superb First HP Rocket

    Our club built 6 of these as a project together to get our HPR1 certs. This is an excellent kit, tight tolerances, straightforward, reliable, and fun to fly. Order the 38-29mm engine adapter with it and you have a super versatile flyer. Would also recommend the chute protector.
