5.8 Are the Aerotech composite motors the same size as Estes/MRC/Quest motors?

Aerotech makes the following 'standard' retail motors in -4 and -7
second delays. The first two motors are the same size as Estes A-C motors.
The next two are the same size as Estes D motors. There are some other
24mm motors that are available from Aerotech that are longer than
Estes D motors. Some of these 'non-standard' Aerotech 24mm motors are listed
after the four 'standard' ones. The F and G motors may be obtained from
some dealers and mail order sources, but are not packaged for retail sale.
