Estes Prototype Motors Part 4
I've shown pictures of the 24mm diameter 'D48' motors.
What about high-thrust 18mm motors?
Sure, there's been the B3.3/B8/B14 and the C5 motors.
How about something with a little more 'Uuumph' in that diameter?
I present the Estes C10 motors.
These motors might have been very close to release in the mid/late 1990s.
Estes had obviously thought out multiple delay types for this motor.
I vaguely recall seeing the motor listed on some Estes publication/packaging but I can not find it.
I heard that it didn't go into production for the following reasons:
1) Extra steps to machine out the nozzle and drill the core
2) So much propellant was removed when drilling the core that the Total Impulse dropped to 8.6 N-Sec.
Pictured here with a current C6-5 motor is a selection of C10 motors:
C6-5, C10-0, C10-4, C10-5 and C10-6
