Eric, shut up, go to Hell.
There is no reasonable expectation for users to read a manual that isn't at the
pad and there isn't any reason to expect them to understand it in 107 degrees
heat.
Launch control wiring has been the same for more than 60 years. Users do not
expect live wires. Ever.
This is a complete hazard and unacceptable risk to destroy the rocketry
community. Such a simple thing. Unnecessary.
I will protect my family and friends. My friends are the entire rocketry
community.

It sounds like there is potential for user error.
RTFM is always a good policy, but as a person who used to write a lot
of M's, we know that not everyone will R T F'ing things. Generally, the
best policy is if the design will save the user from making mistakes if
at all possible, not the manual! In certain situations, I used to tell
developers, "You can't save this design with documentation. You need to
fix the design and save users from themselves."
The danger I see is that if a person is unfamiliar with the design and
procedures, and they assume there is NO WAY it can light the igniter
unless someone is actually pushing the button (or an equipment
malfunction), then it could result in disaster. If the design is such
that after one launch, the system is not automatically safe to hook up
the next bird without removing leads or some other steps to make it
safe, there is a potential to forget. Or there is a potential for one
group to leave the equipment unsafe for the next group.
Of course, I'm saying all this without having ever seen this equipment
and not even a good familiarity with the usual club equipment, and i
don't know what kinds of procedures you had in place. It just sounds
like the system can accidentally be left in an unsafe state.

Thanks Jack,weekend.
Yes, this is the correct sequence to make it work and what we did all
igniter leads to motor
If you want to kill yourself, here is what you do:
1) Don't remove the safety interlock on the transmitter
2) Leave the alligator leads connected to the Receiver, connect
3) Turn on the Receiver - it will make a beep beep beep and thenyou'll hear the igniter pop and the rocket motor light
once when Dennis/Aidan were flying.
And the unit will turn on and fire the rocket if you do this.
This happened twice - once when Mike and I launched a Mad-Dog and
I spoke with them, showed them the above steps (which ARE in themanual) and we never had an issue.

Your sequence must be wrong if you are lighting igniters/rockets
plugged into the relay module
1. When you hook up igniter clips this wire should not be
module should be off and the safety clip out
2. When you hook up relay module plug, your wireless relay
safety clip
3. Now when you turn on Blue unit safety clip is out now put in
an issue with unit
4. If unit now goes off no one is by the rocket and you have a
5. Unit will not turn on unless this sequence is followed
