Quick-Change Motor Mount System

Skill Level 2

This is a unique and exciting accessory for the experienced modeler. As quick and easy as replacing a spent motor casing, you can change the "power house" of your rocket to suit whatever size field you happen to be flying in that day. Originally designed for the Saturn V Series  (3.900" Dia.) kits, this option can be installed in any rocket whose body tube diameter exceeds 2.600". Developed to change the motor mount back and forth from three "C" motors to four "D" motors, to a single "E", "F" or "G" motor in the Saturn V, we have widened the scope of this to work with just about any large diameter rocket. Basically, you tell us the size of the body tube and what motor configurations you desire, and we custom manufacture the kit to fill your requirements. For ease of integration, we highly recommend that this modification be installed at the initial construction of the kit. Basic knowledge of determining a rocket's center of gravity is required.

The current motor configurations available are as follows:

1 X 18mm
3 X 18mm
4 X 18mm
5 X 18mm
1 X 24mm
3 X 24mm
4 X 24mm
1 X 29mm

The motor mount system entails two separate pieces. The primary mount which is permanently epoxied into the rocket and the motor canisters. You need to order one primary mount and then add whatever motor canister configurations you wish to use.
