Estes/NCR Command Control Launcher - Is it a good idea?

Post by DAL » Tue, 04 Jul 2000 04:00:00



I'm thinking about purchasing a Command Control Launcher.  It
can get one for about $40 and I already own the R/C batteries.

Is this a good all-around launcher?  I plan to launch B-G
impulse engines, but mostly E or below.

This approach is cheaper than building my own relay launcher as
described on ROL.  Is there anything that should point me away
from this purchase?  Is the Aerotech Interlock controller better?

Any idea on how many Solar igniters and/or Copperheads could be
launched on one charge from 2-1200mAh R/C batteries (14.4V)?

Can the charging plugs be used with any charger, or only a
specialized one?

Thank you for your help.

I've had a lot of success with mine. I have no idea how many launches on a
charge, but it's good for at least 20 copperheads - I've done that in a
weekend without a charge. I have the feeling I hadn't really approached
the capacity.

I equipped mine with the lower capacity Nikko-brand cells that are sold as
a set with a charger; I just made plug adapters so I could still use the
chargers for batteries OUTSIDE the launcher, if I wanted. As long as you
match the voltage and polarity you should be OK; but, as I'm sure you're
aware, it's important not to overheat the cells while charging. Since I've
never come close to discharging the cells, I don't want to plus them in
for the specified "4 hour" charge - I just charge them until they're
slightly warm.

Good points over the Aerotech: internal battery, standard clips (three,
for clusters, actually) and the ability to run on one cell. For Estes
Solar ignitors, it actually works better to reduce voltage. They sometimes
"explode" without igniting at 14.4V!

Since you've already got the batteries and charger, I would go for it.  I've
used nothing but mine for nearly 6 years, launching everything from Estes mini
A's to I161's and J350's with Magnalite igniters.  I've even used it to fire a
cluster of 10 Solar igniters nearly instantly (about a second after pressing
the button).

As long as I'm not doing a lot of clusters, mine has gone a full summer of
flying (every two weeks, about 7 - 15 flights per launch) on a single charge.
It was even caught in a sudden (less than 10 minutes warning) thunderstorm, and
after opening it up and letting it air out for a day or two, was just fine.  

I always have mine set to 14.4v no matter what I'm launching.  I've never had a
problem with the igniters lighting without lighting the motor(s).  I've also
used it with an extra 50 feet of speaker cable attached to burn a couple of H
motors using thermalite igniters.

One of the best investments I've ever made for ground support equipment.

I would agree with the others here. I've used mine exclusively for both
modroc and HPR flying/igniters with nothing but success. I also always use
mine on 14.4v as John does.

I got one of these inthe NCR Phantom4K starter set being dumped by a local
Hobby Lobby for $20. All I really wanted was the rocket, but the launch
controller is worth a few bucks. I don't know if it is worth $40. Somebody
somewhere must be dumping these cheaper...

Given you have the batteries and charger, I'd think a custom box would be
cheaper. I usually have piles of scrounged from the trash wire. IIRC, all I
actually bought for mine was the plastic box itself, the dual banana jack,
and in the case of the mini box, the DPDTCO 7/14v switch (From American
Science and Surplus of course!). My wire is old current loop terminal cable!

Solars? 5371. Copperheads? 3 :-)

Well, it's not a standard RC servo/charge type jack; it's one of those round
jacks like you typically find on an AC adapter. I haven't checked the size
to see what fits, but it shouldn't be hard to find one. Check the polarity
when you connect it up.

I've got a bunch of assorted chargers. I make most of them with Deans plugs,
and then build seperate leads that plug in from there, so I can use any
charger with any lead set. And it never hurts to have a couple lead sets
with micro-clips on the end, for terminal type batteries like gel cells.
Same with my cycler, it has the same connectors and can use the same leads.
sets.

I have one, and when my friend and I take our kids to launch rockets,
it's all we use.  I think I charged the batteries about a year ago -- I
have no idea how many solar igniters we've fired on it, but it's still
going strong.

The kids also like the beeping...

RC connectors. Available from ACE RC, and IIRC Tower Hobbies. Ask me to show
you one at the next NIRA launch.

Since you already have the batteries and presumably a charger,
you would do very well to get that launcher. I blew $100 for my
charger because I needed batteries. But I am happy with it.

Yep I think it is. I saw one at a NIRA launch last May and bought
one the very next day. I was able to fire a Solar igniter on dead
batteries... So with a full charge who knows?

The plastic case that it is made from is *VERY* soft and is
easuly marred. But that is about it, especially since you
already have the NiCads for it.

While I have been unable to use my launcher yet (I am recovering from
a torn achilled tendon) I would bet that it would handle far more that you
could do in one afternoon.

Good question as they are rather goofy. The instructions say
absolutely nothing about this. I have a TurboCharger which I
use to charge the batteries. In that case I have to remove the
batteries, but I will check the voltage meter to see exactly
when that will be necessary. I am betting I will probably be
able to go an entire season on one charge.

I believe those are the orange ones with the gold plating??? I used to
replace all of my Tamyia plugs with those as they supposedly delivered
more current which was important to my racing.

Hi all,
  Love my Command Control.  It has lit 50 in a day, including copperheads and
clusters, still had plenty of juice for more.  I just bought a 75' chunk of 14
gauge wire to get 100' of clearance (baby H's!!!!) and it lit a 'Fire in the
Hole' ignitor instantly.  Kids love the beeps, too!

Fly straight and often and true!

Nope. Deans plugs are generic RC servo type connectors. They do find for
charging, but do NOT carry the kind of high current needed for a firing
circuit. For high current, use banana plugs, Molex connectors (most RC car
packs use a type of this connector), Jones plugs, or Sermos connectors.

The Sermos connectors are pretty cool. They mate with themselves, and have
little tabs so you can gang them together into whatever array you need. They
have silver contacts, not gold. Silver is actually the best conductor, with
copper second, and gold a distant third. So why does everything from stereo
plugs to computer pc boards to RC connectors have gold pins? Gold doesn't
tarnish, so the connection doesn't degrade. The Sermos connectors are self
wiping.

Well I just did a search for "Deans Plugs" and found that they also make
the high current battery connectors which I remembered. The ones I have
are about 12 years old but the new ones are very similar. Check the
following

I've been running mine on a single 7.2v battery ever since I got it and it's
proved to be extremely reliable even with cluster ignitions.  The beeping
also alerts anyone around that a launch is about to take place.  By far my
favorite launch controller.
