I have a HiMax 2025-4200 with D gearing but was thinking of going to an outrunner. I also have a Little Screamer PP(****) but I think it may be too small, thoughts?

Which is suggested? Billy Hell has one that looks cool. Also I wanted to know thoughts on the HiMax 2812-0850? I heard the Hacker A20-20L was awsome, but the shafts bend easy. ANY suggestion would be appreciated.

I have a Katana and edge 540, both the pro kits.

I have used the Himax 2812-850 and the 20L, both are prefect choices, the hacker does not bend shafts easily. On top of that, they come with everything you need to mount them, and spare stuff.

The Hacker shafts are nearly impossible to bend if you use the prop mount on the can end. The long end of the shaft goes towards the back of the plane.
