Hi Folks,
I fitted my new regulator today - oh why did I use regular stiff nuts on those bolts which meant I had to remove the panel?!
Ah yes, the joy of removing the panel. If I had to do it again I would do a whole lot of things differently/better - maybe we ought to compile a database?
Anyway, test flown and all is well - a steady 14 volts indicated throughout the whole flight, which incidentally took me to my highest altitude ever in my Europa 11,500 ft. Not bad for a 912 with a fixed prop. I was still doing 300 fpm.
Thanks for all the advice on the subject.
Regards,
Martin Tuck

as you know, the original Ducati regulators on Rotax
914/914 engines are not very resistant to heat. I am
looking since a while for a substitute and so I am very
interested in this regulator. Do you have more details
about this regulator?
Thank you.

I have ordered a Schicke GR6 regulator and it is in the
mail at the moment. I will report back.

Martin didn't say what regulator he put in.

What is the price for the GR6?

It was 82 euros plus 16 % German TVA plus 20 euros for
postage to England.
Look on the web site; the specs are the same as the Ducati
one, but some creativity will be needed to connect up the
wiring as there is no connector.!

Hi all,
Some years ago I performed some bench tests regarding Rotax regulators,
the regular Ducati one, and the Schicke GR4.
http://contrails.free.fr/elec_ducati_en.php
The GR4 proved superior in many respects, so I installed it in our Rotax
914four-seater.
It has performed flawlessly for nearly two years.

According to Herr Schicke, the GR6 has the same specs as the GR4n but
thermal characteristics are better. Please note that the rated output is
about 16 amps, quite the same as the ACTUAL safe output of the Ducati.

No big deal with fastons on the wires. You just insert each faston in
the correspondig aperture on the wiring connector. Thus reverting to the
Ducati is a straight swap.
For those with an OV protection, be aware that the Schicke won't shut
down when the sense wire ('C' or 'skinny red') is disconnected or put to
ground. The setup is better as in the last Z16 update on the Aeroelctric
connection.

On Friday my GR6 Rectifier-Regulator (RR) arrived from
Schicke in Germany.
I fitted it yesterday and test-taxiied at high power.
Today I flew it to Conington and back.
This was all generated by my purchase of a new RR at the
beginning of the year after my original failed at 175
hours. The new RR (and all three other new RRs that I
tried) made my analog ammeter oscillate from 1 - 10 amps
at 5700 rpm and from 1- 5 amps at 4600. At the same time
two older RRs lent by other kind souls worked fine with
no oscillations.
There was an implication that I had a wiring fault in
G-OWWW. Nigel Beale's solution was to "disconnect the
ammeter"  I did not find that acceptable.
I did use the 'faulty' RR for about 30 hours and I covered
up the ammeter, almost, to avoid distraction.
Today with Herr Schicke's RR there were no oscillations.
It worked right !
So, although four faulty RRs seems to be unlikely it is
actually true. I suspect that Ducati have changed the
circuit (or are using a different poorer quality
component) about 12 months ago.
I have asked here and on the Rotax Engines list for anyone
with experience of a new RR with an analog ammeter. I was
looking for either "yes I have an oscillation" or "no I do
not have an oscillation" when they had used a new RR. I
had one response from Australia but his engine was now out
of commission for another reason and he couldn't further
confirm his position. I had not a single comment, yes or
no, from anyone else. So I rather assume that no one fits
my description.
I am going to stick with the GR6 for now. I have told
Nigel Beale that he needs to get the new RRs checked as he
is sending out with new engines RRs which will give him
grief when the builders finally start them up.
I will post his reply. I am not hopeful that I will
achieve any progress. Too expensive an implication if they
confirm my findings
I have done my part with my tests over the last 9 months.I
would recommend anyone who needs to replace their RR to
buy from Herr Schicke. The GR6 is and isn't a direct
replacement for the Ducati item. Yes it comes with 5 male
fastons which can be plugged directly into the black
plastic Ducati connector. However the size is larger, and
the wires provided are a bit short. I am going to make up
an adapter to allow me to carry a Ducati as a spare until
such time as I invest in a further GR6.
In the circumstances, after my comments I don't suppose
anyone wants to buy a Ducati RR from me  ?

PS Buying from Schicke in Germany involves sending a money
transfer as he does not accept credit cards. He charges 20
euros for the postage on any number of RRs, so a group
order would be sensible.
