Hints and Tips - OverDrive
||The Overdrive is
a simple model that has recently been enhanced with the inclusion of precision laser cut
fins. It offers a very unique look with a total of 8 fins that are glued together to
form 4 fins that are attached to the rocket. The OverDrive is our least expensive
A detailed description of the OverDrive kit can be found here.
This list provides you with some information that can help in
the assembly and launch of the OverDrive:
- The OverDrive uses a body tube that is the
same diameter as a motor tube. Meaning that the motor tube and body tube are one in
the same. In this model you must recess the engine block by pushing it into the
model with a spent motor casing or similar item. IMPORTANT:
Practice this step without glue FIRST!
- When gluing the fins together, it is recommended that you lay
them on a smooth flat surface on top of a flat (wrinkle free) sheet of wax paper to
prevent the fins from being glued to the work surface. When completely dry they can
be applied to the rocket but must be handled carefully until attached and fully dried on
- Being such a narrow model, the shock cord is assembled from
two items, the elastic cord and a length of Kevlar cord. The Kevlar cord is anchored
(glued) to the outside of the body tube, along a fin/tube joint providing a very strong
connection to the body while not interfering with the deployment of the streamer.
Make certain that the cord is securely glued in place!
- The OverDrive does not make use of an Engine
Hook for positive retention of the motor. Instead you must use what is known as "Friction
Fitting" of the motor. You test fit the motor and if loose (most
often), you apply a short wrap of masking tape around the middle of the motor and
reinsert. Repeat until the motor is VERY snug in the rocket.
Lastly, you will notice that fins of the OverDrive are mounted slight above the
bottom of the rocket. This provides you with space to place a wrap of masking tape
around the end of the motor and the end of the body tube to further secure the motor in
- If the motor that you are using is TOO tight,
it is acceptable that the motor stick out the back end of the model by up to 3/4 of an
