Hints and Tips - Flea
||The Flea is a
simple model in some cases (no engine mount kit, just an engine block) and a bit
sophisticated at the same time (need to cut out your own fins). It is a good first
or second choice for a model rocket kit. The Flea ranks 2nd in cost being slightly
more expensive than the OverDrive
can find a detailed description of the Flea kit here.
This list provides you with some information that can help in
the assembly and launch of the Flea
- When cutting fins it is important to make sure that the grain
of the wood is parallel to the Leading Edge of the fin.
This is identified in the instructions and on the fin pattern, but warrants
pointing out again.
- When cutting, use a straight edge to assure a clean straight
line. Use MANY passes of the knife. Do NOT
try to cut all the way through in one pass. When cutting WITH the grain, the wood
will cut quickly and cleanly. When cutting the other fin edges, it will take more
passes of the knife and result in a slightly more ragged cut. This can be corrected
with sand paper.
- The Flea 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. For our educational bulk packs we include a
complimentary tube that is used for this purpose (the 2.75" long brown tube)
- Being such a narrow model, it is extra important that the
shock cord mount be glued in as flat as possible, flush with the inside surface of the
- The Flea 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 Flea 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 place.
