Instructions:
The Blastcap is simple to use and set up. It was designed without an Ematch feed hole in its side for 2 reasons; one, fishing the Ematch wire through the hole is tedious and two,100% of the black powders force is aimed in the desired direction as a result.
- Position the Ematch in the Blastcaps bottom.
- Add the desired amount of black powder.
- Bend the Ematch wire over the top and down the Blastcaps side. Be careful not to crimp the wire.
- Top off with dog barf or wadding packing down the BP
(just a bit) DO NOT over pack.
- Wrap a piece of tape around the top of the Blastcap and over the Ematch wire. Let a portion of the tape overhang on top so you can fold it over to secure the dog barf and BP.
That's it. Have a great flight!
