Motor Guide Results

Here is your handy guide to the motors that might work with your rocket. We found 17 motors that fit and appear to have enough thrust (773 motors didn't fit, 1 motors failed safety checks). 18 motor had thrust curves available and 32 flight simulations were performed. Browse the motors that did and didn't work right here or download the results as a spreadsheet.

The Rocket

Rocket Name:   Fat Alpha/Omega 18mm
Owner: Jim Lane
Body Diameter: 1.64in
Dry Weight: 2.5oz
MMT Diameter: 18.0mm
MMT Length: 3.75in
CD: 0.60

Motors That Work

These motors fit your rocket and appear to have enough thrust to lift it safely. If thrust curves are available, a quick simulation has been run to give a rough idea of the performance of your rocket on this motor. We encourage you to run a more complete simulation with any motor you plan to use; see the simulators page for more info.

Motors That Fail

These motors fit your rocket, but failed one safety check or another. They may actually work, but you should use them only with caution. We encourage you to run a more complete simulation to verify flight safety; see the simulators page for more info.

  Motor Reason
failedG Estes A8 speed at end of launch guide too slow (46ft/s)

G These simulations were run with a launch guide length of 6ft (rod, rail or tower). If this is not correct, launch guide lengths can be specified for your saved rockets. (The minimum velocity required is approximately 15m/s or 50ft/s.)
