LAUNCH CHECKLIST
1. Disarm the launch system by removing the safety key.
2.
Loosely pack three squares of flameproof wadding into the body tube from the forward end where the shock cord mount is located. The wadding
should slide smoothly into the center of the tube for maximum effect.
3.
Stretch the parachute out by holding all parachute cords at the end where they are tied together and at the center of the parachute itself. Roll the
parachute to fit the body tube easily. A light application of talcum powder to the parachute as it is folded will help deployment of the parachute. Be
sure the wadding has been inserted before inserting the parachute. It is best not to pack the parachute until you are ready for a launch.
4.
Install the nose cone over the recovery device. The nose cone should fit snugly; not too tight or too loose. If the fit is too tight, you can sand the
inside edge of the bodytubeorthe
nose cone shoulder lightly until you achieveasnug fit. If the nose cone is too loose, you can add masking tape to
its shoulder to get a snug fit, or you can build up the inside edge of the body tube with a light application of glue. Be sure the glue is dry before test
fitting the nose cone!
5.
Carefully select the engine for launch. For a first flight, use the A8-3 engine as recommended. Insert the igniter as per engine instructions.
6.
Engine Installation -Insert
the engine into the engine tube mount until it stops againstthetop portion ofthe engine hook. The rear hook must latch
over the rear of the engine. The igniter leads should be positioned between two fins and away from the launch lug side of the rocket. "DOUBLE
CHECK THAT THE LAUNCH SYSTEM HAS BEEN DISARMED AS PER STEP 1 ABOVE".
7.
Fit the launch rod through the launch lug of the rocket. The nose of the rocket should be pointing upwards. Be sure the rocket slides freely on the
launch rod. Attach the launch system clips to the igniter leads. You can use anyone of the three lugs on the XR-20.
8.
Clear the launch area and follow all range and safety procedures.
9. Arm the launch system.
10. Countdown to launch!
IF A MISFIRE OCCURS, DISARM THE LAUNCH SYSTEM AND WAIT
ONE
MINUTE BEFORE APPROACHING THE ROCKET TO DETERMINE THE
CAUSE OF MISFIRE. REMOVE THE SAFETY KEY FROM THE LAUNCH SYSTEM BEFORE YOU APPROACH THE LAUNCHER. DO NOT PUT YOUR
HANDS AND FACENEAR THE TOP OF THE ROCKET...
When you are ready to leave the launch site, we suggest you pick up and properly
