I would advise to replace the prop with another 3 blade prop.


The reason, I liked what I read about the Alpha, it comes with a trainer prop. A 3-blade fairly flat pitch wide blade prop made by Evolution.

The difference is amazing, much slower flight. The 3-blade trainer prop loads the engine and acts as an air brake. The first flight (with an instructor) we used a regular 2-blade prop. The next time I had installed the trainer prop, wanting to see if there was any difference. My instructor was amazed at the difference in the planes speed. It slows the plane down about half. And the approach speed was really helpful to learn how to land.

The trainer prop’s wide blades act as an air brake. At about 100 feet in altitude on approach, with the 2-blade, when you pull the throttle back it glides in nice but at a much higher speed. With the 3-blade prop at the same 100 feet, when you pull back on the throttle, the nose drops a great deal more, pull back on the elevator and it glides in at a much slower speed.

With the 3-blade Evolution trainer prop (12” slight pitch, 60 size) with idle set at 1500 to 1600 rpm’s, then change only the prop (to a 2-blade 12’ – 6 pitch) the rpm’s climbed to over 2400 rpm’s. Of coarse, you can slow the rpm’s by tuning the engine, but it doesn’t have the same effects of slowing the planes air speed.

I personally feel the trainer prop is a great advantage to a beginner pilot.
