Brief:
The Custom Zero Gravity is an easy to build kit with plastic nose cone, die-cut balsa fins, and 12" parachute.

I used a shorter body tube, a streamer and rotated the fins 180 degrees.

Modifications:
I followed the same instructions as building the stock Zero Gravity, except I substitued the parts listed above.

This kit was easy to build. The instructions were easy to follow. No special tools were needed. Just glue, a hobby knife, a ruler, pencil and angle iron. I did use a hot glue gun for the shock cord mount.

Construction:

  • 1 - 5" BT-50 Body Tube
  • 1 - Plastic Nose Cone
  • 1 - 18mm Engine Tube
  • 1 - Engine Hook
  • 2 - Centering Rings
  • 1 - 18mm Engine Block
  • 3 - Balsa Fins
  • 1 - Plastic Streamer
  • 1 - Elastic Shock Cord
  • 1 - 1/8" ID Launch Lug
  • 1 - Water Slide Decals from Estes Mini Max Kit
  • 1 - Paper Shock Cord Mount

The finishing was simple. I just sanded, primed and painted the finished rocket. I painted it the suggested stock blue color, but added some red fade in at the top of the body tube and tips of the fins.

I applied some waterslide decals from an Estes Mini Max kit instead of the stock Zero Gravity vinyl wrap.

The rocket was much smaller than the stock rocket so I put a streamer.

Flight:
I flew the rocket three times on A8-3 motors.

I would recommend this motor for this rocket, especially when launcing at small fields. This rocket flies much higher than the stock rocket on the same motors.

I drag raced it with both a stock Zero Gravity and an Estes Mini Max.

Summary:
It is a great flying rocket mod. I will definitely keep flying it.
