Motor Guide Results

Here is your handy guide to the motors that might work with your rocket. We found 65 motors that fit and appear to have enough thrust (737 motors didn't fit, 9 motors failed safety checks). 74 motor had thrust curves available and 156 flight simulations were performed. Browse the motors that did and didn't work right here or download the results as a spreadsheet.

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 Cesaroni G46 speed at end of launch guide too slow (40ft/s)
failedG Cesaroni G79 speed at end of launch guide too slow (45ft/s)
failedG AeroTech G69 speed at end of launch guide too slow (47ft/s)
failedG Cesaroni G58 speed at end of launch guide too slow (40ft/s)
failedG Cesaroni G50 speed at end of launch guide too slow (36ft/s)
failedG AeroTech H73 speed at end of launch guide too slow (45ft/s)
failedG AeroTech H45 speed at end of launch guide too slow (47ft/s)
failedG AeroTech I49 speed at end of launch guide too slow (35ft/s)
failedG Cesaroni I55 speed at end of launch guide too slow (38ft/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.)

Download the Results

The data is presented in a compact form in the tables above, broken down by motors that worked and those that did not. If you would like to analyze the data further, this section provides download links for files in a generic spreadsheet format (comma-separated value, or CSV) that can be opened with almost any spreadsheet program.

CSV Excel   Download full details of the simulation runs with the various motors:
that worked, that failed, or all of them.
RockSim   Download the list of motors that fit your rocket into a batch for use with SMARTSim. (See the Simulators page for more info.)

You should download these files to your machine and then open them. Normally, clicking the link will prompt you to do this. However, if your browser insists on opening the file as plain text, you can right-click (control-click on the Mac) on the link and chose Save File As (or similar).
