Twin lead wire
10 meter spool.
To make one very long igniter in case you forget your launch box, or a lot of smaller ones if you like to fly more than one time a day.
Just cut it to the required lenght and strip one end 1-4 cm. Put the stripped end in the Caveman Strip and Dip mixture and let it dry over night. The igniters can be use with a low voltage system like 4 AA batterys , but with will ignite without any delay when hooked op to a 12 V system.
