  1. Get yourself a Twitch!

    Posted by Tim Cubbedge on 3rd Jul 2018

    Great little flyer. Easy to build. I added a glass NC so I can put a GPS tracker in it.

  2. Quick build

    Posted by Steve Kendall on 9th Nov 2016

    Got this kit in a pre-black Friday sale. Everything fit very nicely, requiring only minor and expected sanding to prep for assembly. This kit came with a 54mm MMT, but I think I'll limit it to J class motors. Wish it came with a parachute (4 stars), but otherwise a nice, simple L2 kit.

  3. Our L1 cert rocket

    Posted by John Kovac on 24th Sep 2015

    My son and I just got our L1 cert at XPRS this weekend with this kit. We got in two more great flights after the cert flight as well, and the rocket is still in great shape. This was our first HPR, 1st fiberglass, 1st epoxy build, and this kit turned out to be a great choice. As others have pointed out you could do an L2 cert with it as well.

  4. My Level#2 Rocket

    Posted by Adam Dean on 18th Jun 2015

    This is a fantastic kit, all parts fit snug and it did a great job for my Level#2 Certification. I stuffed a six grain Cesaroni J354 in this bird and made a successful mach flight over a mile high (5998') I would Highly recommend MadCow to all my friends. See ROC website for photos, graph and on board video of my level#2 Flight.

  5. Great Kit!

    I bought the Twitch and used it for a successful level 1 flight. High quality parts and a very sturdy rocket!
