hezik,
I had no motor heating issues with the 18x12 prop, was just being careful with the
kind of temperatures we experience in the summer here in Texas, as a matter of
fact I like the way the airplane flies better with the 18x12. Silvestri says he uses
the 18x12 in his Wind 110.

Silvestri doesn't fly the 110. He might have, a few times, but not constant.

For a flight of 10, it'll be ok.

If you want to fly more, you'll kill your engine. Hacker also confirms this. According to Hacker itself, even 18x10 is too much.

On a moderate day, temperature-wise, here, say 21 degrees celcius, flying with the 18x12 leaves my angine at about 65 degrees after the flight.

You problably wouldn't find that too warm, but it is. If you do that often enough, the magnets lose strength.

A programmable brake isn't a mircale thing. Sure it makes a difference if you have an ESC with a really programmable brake, like the Master Spin 90, or the Schulze, but it won't solve the issue with this plane.

The prop is too small to really brake it. I have looked for 18x10W props, or maybe even three-bladed props, but there aren't any in this size (electric).

The 110 has low wing loading, relatively small frontal area, relatively thin profile. So it accelerates.

I have not yet seen a video of this plane not accelerating.

Don't get me wrong, I love this plane, but I'm not blind to it's shortcomings.

Our Dutch F3A champ has flown mine and someone elses, both with different ESC. This is someone that made it into the semi-finals on the WK F3A. He came to the same conclusion.

They even advice the .50 size bipe over the 110 size, because of the acceleration. You can brake the bipe by using the ailerons.
