How Not To Use A Raise Spring TIP

The picture to the right is how not to use a Raise Spring . . . 
Odd'l Rockets Raise Springs should go under the model - not up the side of the rocket as shown here.

DON'T SET THE RAISE SPRING UNDER A LAUNCH LUG THAT IS GLUED A FEW INCHES ABOVE THE LOW END OF THE BODY TUBE.
Your rocket could get hung up at ignition and not leave the launch rod. You could also scratch up the side of your rocket as it scrapes against the spring coils.

Set the Raise Spring UNDER the model. The spring is designed to raise the model a few inches above the blast deflector. The weight of the rocket locks the spring on the launch rod.
Keep the brass tube arm away from the nozzle flame. You could burn a hole in the brass tube!
