I was using the old style Zinger Pro and was getting 8500 I now have the new style Zinger Pro and am getting 7800, anything less than 7800 would be lugging the engine IMHO. The 20-8 would be too much prop especially to break it in on, I broke mine in on a 17-8.

First, the Top Flight Power Point 20X8 is a very poor performing prop compaired to the Zinger Pro or an APC.
Second, I run 20X8's on my 2.13 BGX. I think it would be just a little too much for your 1.60 FX.

Once broke in the OS 1.60 FX will happily swing a 20x8 without over heating problems. My experience with this prop showed it gave a very consistant speed in all attitudes of flight. Just don't use that prop for breakin. An 18x8 would be a good prop for breakin. You might want to switch from an OS #8 plug to an OS F plug if you plan to swing bigger lumber. Yes, I know this is a fourstoke plug.
