HI all,
Our club has just swapped the J160 for a J170. I've just tried it out. having gone up with the instructor for the required type conversion, and than I did a couple of solo circuits.
Our club used to own a Jabiru LSA, in which I learned to fly. Then we switched to the J160. The new airplane seemed more docile, quite a bit more stable around the vertical axis, albeit it lost some climb performance, being heavier than the LSA with the same engine. The roomier cockpit and extra fuel were welcome changes. One thing I didn't like at all was the electrical flaps, but that, I suppose, is a matter of personal preference.
In the end, after getting used to the differences, I quite liked the J160. It was a very nice plane to take a passenger for a ride (provided the pessenger was not too heavy).
Now, my first impressions from the J170 were not very favourable. I didn't really notice much difference in the climb performance, but that could be due to many factors such as the amount of fuel, air temperature and humidity; to see the difference, the two aircraft would need to be tested by the same pilot at the same TOW side by side.
In the circuit, performance seemed more or less similar to the 160; the ailerons seemed a little heavier. Putting flaps down produced a pronounced nose-down attitude, especially evident on the final; this "nose dive" attitude could easily scare the dickens out of an unexperienced passenger.
I approached at 60 knots, flared and it floated ... and floated ... and floated. I've done about ten landings in it so far, and every time it would float, and it seemed forever before it touched the ground.
I have no doubt that the Jabiru people did a great job on this aircraft, and all the changes are well justified. Also, I'm not a very experienced pilot, and maybe I've had too little time in the J170 to learn to appreciate its advantages. This is just my first impressions, and in this thread I would love to read opinions of other pilots who switched over from J160 to J170, their impressions and comments.
Cheers,
Andrei
