The PTS is supplied with a 3 blade 10x5 prop.... not a 9x3.

It is set up this way to slow the plane down.

It does not slow the plane so much that you must run it at full throttle.

This is a mistake I've seen many instructors make, as they THINK that they plane is flying too slowly and will stall out.

I usually end up calming their fears by letting them try out my plane, and encouraging them to run it at 80% throttle.

They are quite amazed that it doesn't "fall out of the sky" this way.



Nor is it unresponsive.

The default control throws are at 75%. These must be taken up to 100% to get the plane to fly properly.


The gear is not any more fragile than any wired gear trainer. Some planes came with loose blocks, which is why a once-over is encouraged as per the long PTS thread, to avoid such problems.


The flywheel helps make the engine easy to tune for the newbie.
Once they have progressed to the point that they are taking off the training aids, it can be removed as well.
But the flywheel does not greatly and adversely impact the plane's flight characteristics. I flew mine for quite a while with the flywheel in place.


The plane does tend to yaw left at runup more than a usual trainer. This is one reason that an instructor is almost a must with this plane.
