Lets get that loser Frank to explain why he's killing children with his
launch controller.

Yeah, Dennis, we had a long talk about that one too - the flag dragging,
the nudist cyclists, the druggies high on LSD who showed up to "watch the
pretty rockets"

I'm hoping she didn't see the nudists - that was pretty disgusting

Yes, we talked about that too.

For the record, I am not butt-hurt by Cliff's response. In a way, he
proves my point that people make mistakes reading or actually don't read
everything thoroughly, so you can't rely on a manual to make an inherently
unsafe thing safe.

hey guys
Look, this is a serious issue - a product like this shouldn't even be on
the market, Cliff got pissed and didn't read through the email and i am
sure he apologizes.
There are so many levels of wrong about this Rockcontroller I'm not even
going to go into right now ... I like to get all of my facts straight about
the situation and
I need to talk to Frank about this before I do anything about it - but I
will be doing something about it - as far as I'm concerned, this unit
shouldn't even be on the
market.
Those of you guys who know me know that safety is a big thing for me, this
is why I went out and helped invest in the club launch system because A) I
know the
guy who designed the system and he is solid electrical engineer (Ron
McGough - Blackdog Rocketry), B) it needs to be rock-solid as if your life
depended on it
(it does) and C) I reviewed the circuitry and schematics for the
continuity check and relay circuit myself - it's physically impossible for
this to fail unless there
is a mechanical failure.
let me get the data together and we'll decide to do what's next ... what
really pissed me off the most right now is that there is no online site for
it:

And no, I shouldn't have to google to find a point of contact for a device
like this.
But the same guy is out selling his "Tiltometer" and from what I can tell
it was put together with bubble-gum and bailing wireas well.

If not being ironic, you need to reread my post. I am totally in agreement
with you. The design is unsafe, and you can't expect a manual to make it
OK. That was my point.

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 f or 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,
Yes, this is the correct sequence to make it work and what we did all
weekend.
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 connec ted to the Receiver, connect igniter
leads to motor
3) Turn on the Receiver - it will make a beep beep beep and then you'll
hear the igniter pop and the rocket motor light
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 once
when Dennis/Aidan were flying.
I spoke with them, showed them the above steps (which ARE in the manual)
and we never had an issue.
Clear example where you need to Read The F***in manual (RTFM) :-)

Your sequence must be wrong if you are lighting igniters/rockets without
pushing any buttons
1. When you hook up igniter clips this wire should not be plugged
into the relay module
2. When you hook up relay module plug, your wireless relay module
should be off and the safety clip out
3. Now when you turn on Blue unit safet y clip is out now put in
safety clip
4. If unit now goes off no one is by the rocket and you have a an
issue with unit
5. Unit will not turn on unless this sequence is followed
