Antares 18S Maiden Flight

I don't believe that there is anything wrong or suspect
with two stroke engines. You do have to be careful
with them, here are the things that I've learned from
motorbikes and glider turbos

Use the best sparkplugs you can get to avoid two stroke
whiskering, try platinum or exotic equivalent

Take care of your plugs

Do a DI of your engine before flight, are all the bits
there, eg, the HT leads are ON

Take scrupulous care with your fuel/2 stroke mixing

Prime your engine before takeoff

Start your engine before starting task, 2nd starts
are always much quicker for some reason

Remember the sequence fuel on, erect, ignition, TE
change over, push prime, pull decomp speed up and release.

Sounds dificult but it isn't with practice - this on
a Ventus c so its a bit old tech compared to ASW 28
and ASG 29s or DG1000s.

After a couple of months layoff the engine is much
slower to start and needs determined effort to get
it going. I presume that it needs to blow oil out of
the crankcase and cylinders.

Never had a problem with my Discus Turbo (apart from
finger trouble).

Always prime it. Always start and run it for at least
20 secs before leaving site/starting task.

Has anyone mentioned that it confirms that the logger
engine noise sensor has worked properly?

Yes. It has no starter. (And, btw: Even if it had one,
the simple fact
that it starts *now* doesn't mean that it will start
*then*.)

My bad - never looked closely enough at a Turbo.


2) Do many pilots flying sustainer-equipped sailplanes
presume that the engine is unlikely to start and not
care,

Yes and no. Yes, flying a sustainer we *always* presume
that the engine
is unlikely to start. And no, we actually care. Thats
why we never rely
on a ststainer but only start the engine over a landable
field.


That part I know. I was trying to ask a slightly different
question, which is: if sustainers are less reliable
on a first start than a second start and pilots don't
do some sort of runup prior to heading out on course
is it that they just don't care that much if the engine
fails to start when called upon - forcing them to land
out? Or is it that they don't believe the second start
story? Or do most pilots actually do a runup (from
an air start of course!), prior to going out on course?

Well, if you want to score your flight anywhere, you need to have the engine
in operation somewhere during the log so that the engine noise/vibration
sensor is verified.
You can do that after returning home, of course, but it would be more
sensible to do that before leaving.

Now you suggest that.

Good heavens!!!
I strongly suggest you start using different ropes!
