Easy Operation
The installation of the ignition system
is in our view self-explanatory.
The start-up is quite simple:
If no RC-monitoring is desired, then
simply power the ignition and start
the engine. If everything is connected
correctly, the engine starts - due to the
more powerful spark- no later than 3
times.
Practical experience:
The original ZENOAH engine (tuned
slightly) in my NoMercy turned about
500 rpm higher than the standard
magneto ignition (load condition).
Reason: the ignition spark is more
powerful. Hence, the combustion at
high speeds is enhanced. For the 3-
and 4-cylinder engines it looks even
better: with the magneto ignition the
energy of the red primary ignition coil
had to be distributed to the two grey
secondary coils, resulting in a weaker
spark. Now, the motors can finally
show their full potential.
The ZENOAH had to be further
revised because of operation time, as
an interim solution we installed a
RCMK-based engine with Michi-
Manz-tuning and a brass flywheel. As
a consequence, the engine functions
much better and works with 2
Graupner 76 propellers, which was
previously unthinkable. Nevertheless
the weight of the NoMercy is too
much for a single 26 ccm plus splitter
gearbox, so the logical consequence
is: installation of our 2-cylinder
engine.
Currently, we are building a 30 kg
Mono with our RAT HOUSE and the
POWER SPARK ignition, when we
are finished, we look forward to
reporting back our results.
What works very well is the splutter
function that is activated when the
battery voltage is low. Even in the
fray, if several boats whisk the water
the same time, one can see very well
that the rooster tail interrupts shortly
and then resumes. Below the selected
stutter speed (in my case 11000 rpm)
the engine operates as normal, so one
can ride to shore normally.
Right now we have finished adding
more function to the ignition system:
Speed dependent output for pump,
throttle, signal etc.
Switching output (flashing or non-
flashing) to signal engine stop
(blink a LED)
operating time counter
alternating display of battery
voltage and maximum achieved
engine speed automatically after
engine stop (adjustable)
