Hi Guys,
My Rotax 912 uls oil changes every 50 hours max, and plugs, little 100 avgas mostly
premium unleaded, 1074 hours suddenly vibrates at 3000 revs.
gearbox cogs replaced... all good!
Don't know what would have happened if I hadn't replaced the gears, but the point
is a "stitch in time". It's all very well to not follow a maintenance schedule
and think its OK, or even to follow meticulously a schedule and think its
all OK, but the truth is, ignore the everyday signs of your engine at your own
peril. If it sounds wrong, go looking, if it behaves differently, go looking,
if it leaks oil , go looking. If the gauges show a change.., if your fuel consumption
increases.. etc etc.
And you still may miss something of course, but the name of the game is keeping
the odds in your favour.
The way we jump into cars now without even a cursory glance under the hood isn't
good training for a pilot!
cheers
Gt

Don't rule out the EIS. GRT make a great product, but my EIS gets grumpy in
cold weather and the altimeter resets to -2,850 ft. I'd have thought
subterranean flying would be darker, but I can see no difference except
that the altimeter reading gets smaller as I ascend.

It is the 360-004 for the single pole (single wire) sender
and the 360-430 for the double pole (two wire) sender. Both are 0-150 psi senders.
The fuel sender is the 360-043 0-30 psi.
