| Subject: | tacho ballast resistor question |
Im wiring my Europa XS with a 912ULS engine. I have fitted the factory-supplied
UMA tacho and am also taking the engine tacho output to a MGL E-3 engine instrument
and a Smart Avionics CSC-1 prop controller.
The UMA manual calls for a 270 resistor across the engine tacho output (if the
readings are erratic). The MGL manual calls for 220 (and one is supplied).
With no electronics shops open nearby in lockdown, its going to be awkward buying
a single 270 resistor. Does anyone know if using the 220 resistor Ive got would
make the UMA tacho unhappy? And conversely, would using a 270 make the MGL
instrument unhappy?
in friendship

hello,
Do you know if Europa Aircraft LTD is open during the crisis covid?
Can they send parts ordering?
I send mail for a quote at enquiries@europa-aircraft.co.uk but no response.
Thanks
Olivier

Hello Rowland,
If I were you I would get a potentiometer (about 1K) and firstly try it in lieu
of a fixed resistor.
I would be looking for the lowest resistance at which either instrument plays up
and similarly the highest reading and then use a fixed resistor of the mid way
value.
BUT THEN ....... We are not in lockdown.
If I WAS in lockdown, I would try the 220 ohm resistor and see how it goes. It
certainly wont do any harm.

Duncan - thanks for your message, thats very reassuring. Your instructions must
be a different edition, there is no such wording in my UMA manual, just the suggestion
I quoted of a 270 resistor. I felt it probably wasnt critical, but wanted
to find out if anyone knew better.

Roland, go ahead and use the resist do you have. Theres no concern with harming
the meter as the resistor is simply dampening the input signal a little bit.
The difference between the two will only make a minor difference in your reading.
If you have access to an optical tachometer, you can verify your meter reading,
as meters do tend to vary a bit.

| Subject: | Instrument Panels |
Just wanted to share this to see if it might be useful for anyone else. I'm in
the process of designing my instrument panels for my Europa XS tri-gear. I bought
aluminium panels from Europa as a mod kit and hacked away at them and made
an OK job. However, I have now changed the design layout and need a new set of
panels to hack at! As I can see this being a bit of an iterative process I decided
I would prototype them using my 3D printer.
I have created the panels in Fusion360 and can manipulate them as much as I like,
print them to check and when I'm happy with the layout I can export the files
from Fusion360 to get them laser cut. Worth the effort of modelling them, saved
a lot of time and effort so If anyone wants the cad files Im happy to share.
Stay safe. Alan
