No flight data available on a 915 in a europa; this is all work undertaken in a
3D modelling environment... a limitless sandpit.
W&B is just that. More weight up front means more required in the rear; very simple
equation. AUW increase and higher stall speeds will be the major result plus
added stress/strain load factors upon the factory space frame.
Flight characteristics would be know different than adding 30kg loading to a standard
europa; except the extra torque of the engine will improve acceleration
and energy to overcome total drag...
You never get the above without more BTU's going in; that's a fairly fixed formula.
The Europa is a very low drag airframe; its pretty much as good as it will ever
get straight out of the box.
More torque at the propeller is pretty much the only improvement available to increase
its performance.

The 915iS has just gotta be too heavy, and being longer making it even
worse. I heard 220lbs+ with intercooler etc., plus a heavy airmaster?

Agree; there are better options available offering more power with less mass up
front.
Some fun for a change today, getting creative adding a few hundred grams of rigidity
with an upgrade to the cockpit interface.... with the empennage shelling
completed shortly will very quickly be able to re-assess the airframe in carbon
construction.

Alan
Just so I am clear, does the Trutrak need the GPS track data that it uses to set
up the compass cardinals every time it is switched on or is this just a one-off
requirementduring initial commissioning?
If the latter then that would mean I wouldnt have to have the GPS permanently installed?
Maybe thats too much to hope for!

According to the manual after calibration - I have just recalibrated mine- it will
then continue to use the internal magnetometer when the GPS is disconnected/failed.
I need to test that concept when the Wx and the state of the strip lets me fly
again.

Meet Lars... he is a software analyst from Hlstebro and will soon be certified
to operate the undercarriage lever on his own and receive a retract rated endorsement!
Lars has only recently taken up flying on weekends, and also likes fishing for
trout and going for romantic walks on the northern ice shelf to watch the pretty
lights.
Being still quite new to flying Lars has a very low degree of situational awareness
and prefers watching the blue dot on his ipad screen...

Thanks, Alan. It will be interesting to see what happens!
Assuming the magnetometer is not affected too badly by electronics around it, then
using it to fly a simple, manually inputted magnetic track, without it requiring
any further GPS input, would make life very simple, especially as in the
U.K. at the moment magnetic and true tracks are virtually interchangeable.
Is Brimpton waterlogged at the moment?

Weve had three inches of rain this month plus about four inches in last week of
October.
Going down tomorrow to check on aircraft and airfield.
I routinely fly with a track set in AP without a route on GPS but have to pull
it (gps) out of panel inflight to check failure mode.

for the AP to get its reference about whether to turn or not, from a dedicated
GPS feed, which is where the idea of the puck came in (since the pucks looked
small and neat). I hadnt planned to get it to follow a magnetic heading using
the APs own magnetometer (unless Im missing something here - why would it then

Are there any experts out there that can tell me whether the Garmin GPS 18x 5Hz
puck that I have been offered, will work as a feed to it? As far as I can understand
from the various manuals, the Trutrak can only be set up to 9600 baud,
whereas the default baud in the 18x 5Hz is 19200. It seems possible to reprogram
the 18x 5Hz to 9600 baud but the process looks very complicated for those
of us not used to Garmin code (and who also don't have a PC with serial port!)!
Alternatively, are there any simpler 'plug and play' GPS 'pucks' that have
been found to work well with the Trutrak? Thanks!

Thanks Pete, you are right, a 915 with an Airmaster using published
figures comes in at 217 Lbs, so the 220lbs+ would be the real FWF
weight, along with the longer arm. I checked with Europa, they said they
were unaware of any installed 915's and were unable to confirm it could
be done. I would love the extra horsepower but just don't want to be a
test pilot : )
Cheers,
Brian Phillips.

Brian the Edge Performance engines are worth looking at if forward mass is a concern...
the Gen4 6cyl Jabiru is said to finally be showing reliability but i
would still choose Edge over Jabiru
