Thoughts on the Pipistrel Sinus?

We owned one for a couple of years.Â* It's very light and was a handful
at Moriarty during our windier months.Â* It will thermal and gain
altitude, but not with a sailplane.Â* It's a great cruiser, capable of
exceeding redline in level flight, so be careful with the throttle.Â* The
Rotax ULS delivered 100 hp with no more than around 7 gallons/hour at
max power, IIRC, and it cruise it burned under 4 gph.Â* Oh, and it has a
ballistic parachute.

I was thinking to use it as a long distance low cost/hr cruiser. Sort of like sailboat cruising. Not in a hurry to get where I'm going.

What do you think about its thermaling ability? Do you agree that visibility in, say, 45 degree banked turns is terrible? or is it like, say a Cessna 152 (not great but not terrible)? I wouldn't be soaring it with other gliders in gaggles or such. Just cruise-thermaling to save fuel.

Was also thinking to use it to teach off-field landing approaches at various clubs around the US.

Glide ratio appears to vary depending on config. 30:1 is advertised but tech data shows 27:1 for one model and 23:1 for the heavier model:

My flights in a Pipistrel Sinus showed that in a 45-degree bank, the sink rate is quite dramatic, and it takes strong thermals to soar effectively. I enjoyed giving rides to power pilots in which we'd fly around for awhile in airplane ,mode; then I'd stop the engine and feather the prop, and let the airplane pilot glide to a landing (they always handed it back to me at pattern altitude).
Lots of fun, but not a "sailplane" in the XC sense. I can't imagine flying it in weak conditions.

If you are interested in a Touring Motorglider, the Phoenix is the way to go. With the wing tips removed (takes 30 seconds, each weighing 15 lbs) the wingspan is 35 ft and the plane will comfortably fit in any standard T hangar. The Sinus wingspan with tips removed is over 40’ making it a challenge to fit in a regular size T hangar.

My Phoenix is not a substitute for a hi performance sailplane, I've owned a few, but it is a substitute for a light airplane, it is easy to live with, has the big canopy sailplane view, 2 seats side by side, doesn't need a towplane, of which I've owned a few, and climbs nicely in good lift.
Mine has the optional tow hook, haven't used it yet, but its there in case I ever want another sailplane, nearest tow for me is way too far away,
living on an airport means in a few minutes I can be checking out the clouds or taking a sunset flight down the beach.

Hey There Russ Owens
Hello to you and yours!
Thanks for the response.
Question on the ASH25E
It the Rotary engine eats itself up and you drop it off at Rex's shop to fix it, whats your educated guess to completely replace it with all the extra bits.

Probably should ask Rex, or pilot that's had to do it, and not somebody like Russ
(or me) that hasn't had any problems.
