Are there technical drawings available showing dimensions
and weights that I can use to assist me in building rockets?
YES- The Rouse-Tech website has that posted under “technical
information” for you to download.
the Rouse-Tech “Monster Motor” hardware compatible
with other hardware?
YES. Our hardware is machined in the same facility as other approved
Aerotech RMS hardware and is cross compatible. The only difference
is the color of the anodizing.
are the colors of Monster Motor hardware?
The 18mm, 24mm and 29/40/120 hardware features a gold case, gold
forward closure and black aft closure.
All 29mm, 38mm and 54mm products feature gold cases and hard anodized
forward and aft closures. Forward seal disks are not anodized
at this time.
The 75mm and 98mm hardware uses blue anodizing on the cases and
forward closures and a hard anodized rear closure with double
the anodizing thickness as the smaller motors for that added protection.
there a warranty?
Yes. The hardware is warranted against motor failures caused by
manufacturing defects for one year. The proper procedure to follow
in the case of a motor failure is to send the hardware to Aerotech
for inspection. After review, either Aerotech or Rouse-Tech will
warranty the replacement hardware based upon the cause. Every
failure should be presented to the motor vendor at the launch
for a preliminary review.
can Monster Motor products be purchased?
We have an extensive dealer network established that will support
you and your activities. Most have product in stock. Please visit
our dealer page on the website to find a dealer that suits your
needs. Some people like to purchase from dealers that attend and
support their launches, while others like the ability to buy online.
I use an open closure instead of a plugged closure in a flight
that uses electronics?
Certainly. Care must be taken in reading the propellant re-load
instructions so no in flight problems arise. I have seen failures
due to gasses escaping through the forward closure and igniting
the ejection charge or gasses entering the compartment above the
motor, causing harm. If the o-rings are not installed properly
in the delay compartment, gasses can escape past the delay grain.
As a safety precaution, I recommend using a plugged closure whenever
you are using electronics.
tight should the closures be, and should they thread all the way
into the case?
The design of the RMS hardware, their threaded closures and casings
is intended to satisfy a key engineering need. Motors are able
to be threaded to compress the o-rings to a proper amount, each
time a motor is used, regardless of the manufacturing tolerances
of the liners, grains and parts. It is normal for the closures
to tighten up prior to them threading all the way into the case.
There should be a slight gap. If you tighten up both closures
and they seat all the way into the case without a snug o-ring
fit, no not fly it. That means that the liner is too short and
the o-rings have not seated properly. Contact your dealer and
obtain another liner that is longer.
