Brief:
This is a 13mm version of Art's larger 24mm Qubit. This is the first all cardstock kit I've built that is intended for 13mm motors. It is a free download and is contained entirely on one sheet of colored cardstock, including the instructions. I built a beta version that was pre-printed and one that I printed myself. The latter is called 'Dicey' as it resembles a die.

I know this may be somewhat repetitious, since there are already two nice reviews on this mini-Qubit, but mine was mostly written before those were posted. So here goes...

Construction:

Art Applewhite 13mm Qubit

  • Cut out the body, which consists of a single cutout for both the outer shell and bottom sections
  • Cut the launch rod and motor mount holes
  • Form and install the motor tube

The instructions tell you how large the side of one of the cube faces should be and I recommend you verify this measurement. On the version I printed, the cutout was a tad larger than it was supposed to be. The only issue this caused was that the motor mount hole, was also a bit too big. I compensated by making the cutout of the motor tube a bit longer. Once it was wrapped, the OD was also larger and fit nicely into the motor hole.

Finishing:
Finishing the plain version is up to the individual but I was happy with the day-glo orange mine was printed on. The Dicey came pre-marked.

Construction Rating: 4 out of 5

Flight:
The only recommended motor is the A10-PT. All you have to do is friction fit the motor and offset the rocket 6" or more from the blast deflector.

The A10 gives this rocket a nice jump off the pad. Both my Orange Qubit and Dicey flew straight despite the 15+ mph winds. The Orange one suffered some damage prior to launch when the LPR rack blew over. However, with a little masking tape, it was good to go.

Recovery:
Aerobrake..'nuff said. The Orange one landed one car away from my SUV and Dicey actually hit my range box and came to rest just under my SUV. I guess the wind was fairly uniform from flight to flight.

Flight Rating: 5 out of 5

Summary:
Fun, easy, and FREE! This little guy really rips on an A10! The only issue is that the cardstock will warp easily and may deform under A10 power, but remember the cost!

Overall Rating: 4 out of 5
