LOL!!Gotcha !
So how about this ole-timey, tried -n- true method for determining the CP of a rocket that you KNOW is stable for those pesky RSO's:
Tools needed:
PENCIL
ERASER
RULER
FINGER
In addition, you will need:
A LOADED ROCKET, ready to present to the RSO and fly
Before approaching the RSO, say back at your Prep Area:
1. Measure the diameter of your LOADED ROCKET
That measurement is called One-Caliber.
2. If there is already a CP marker on the rocket, use the ERASER to remove it.
3. Balance the LOADED ROCKET on your extended FINGER.
That is the CG
4. Use the RULER to measure One-Caliber backwards from the CG, toward the Flamey End of the Rocket
5. Mark that point on your LOADED ROCKET with your PENCIL
That is the CP
6. Proceed to the RSO and if the RSO asks, show them the CP marker.
7. Fly your stable rocket
-- kjh
I have a few RSO stories - best left unsaid - that would REALLY leave you scratching your head. Some of these guys shouldn't be at the table.
