Motor Guide Results

Here is your handy guide to the motors that might work with your rocket. We found 4 motors that fit and appear to have enough thrust (807 motors didn't fit). All motors had thrust curves available and 8 flight simulations were performed.

The Rocket

Rocket Name:   Estes Humdinger
Owner: Warren Taylor
Body Diameter: 14.0mm
Dry Weight: 20g
MMT Diameter: 13.0mm
MMT Length: 2.50in
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.

  Motor Weight Launch Velocity Accel Altitude Time Delay
OK Estes 1/4A3 26g 17m/s 21m/s 18.7G 22m 2.2s 2s
OK Estes 1/2A3 27g 22m/s 39m/s 29.0G 72m 3.9s 3s
OK Estes A10 28g 24m/s 62m/s 44.3G 175m 5.9s 5s
OK Estes A3 28g 18m/s 69m/s 20.2G 200m 6.4s 5s

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).
