Rocket Preflight

A. Crumple and insert one-half of a sheet

of recovery wadding into the body tube.

B. Fold that parachute and insert it into

the tube with the shock cord. Then insert the

plastic transition section onto the tube.

C. Tie a string from the loop inside the

transition to the altimeter for extra security in

case the rocket comes down in two separate

pieces. Turn on the altimeter and insert it

into the rear of the payload tube (closest to

the vent holes), and then insert the shoulder

of the transition too. Place the NAR payload

into the forward end of the payload bay, and

then insert the nose on top.

D. Wrap tape around the perimeter over

the two ends of the payload tube as shown.

Make sure not to cover the vent holes for the

altimeter.

E. If flying the sustainer alone as a single

stage, it is preferable to hold the engine in

the tube by wrapping tape about the portion

of the motor that extends out the rear of the

tube as shown.

F. If you're flying the Midge as a two-

stage rocket, the motor in the top stage is

friction fitted into the tube.

G. For the booster stage the motor is

inserted so the motor extends out the back

3/8" (0.9 cm) and then held in place by wrap-

ping tape around the perimeter of the motor

and the tube.
