Still More Igniter Tips

For me, sometimes the paper retaining tape on Estes igniters is too far down the wires.
On the left is the igniter right out of the package. The inset picture shows the paper slid about 1/8" up the wires. This allows me to make the "U" bends easier.
At club launches I rarely see anybody bending the wire ends to a "U" shape. This bend doubles the micro clip contact. Most micro clips on club launchers are pretty charred up and worn out.
The bend helps with igniter wire contact.
I first saw Bill Gibson mark the paper tape with the engine name.
Below the designation is an "E" for Estes or a "Q" for Quest. The "X" tells me wadding has been installed.

The inset picture shows the wires slightly and carefully spread apart. Sometimes the wires get a little too close when the igniter is slid into to nozzle and bent to the side.
While holding the pyrogen (or new clear goop) between two fingers, the wires are carefully spread apart, just a bit.



Just for extra insurance, a 1/4" wide strip of masking tape was wrapped around the engine and over the engine hook.
On this older 18mm adapter, the engine hook was slightly bent away from the side of the engine casing.
