I just wanted to address the weight issue that someone mentioned about the Fox 40.
My Fox 40 abc /bb delux.. set up with a Big Art tube muffler ,
zinger xtra wide blade 10x6 prop, fox spinner nut, weighs in at 11.8 0zs, and
this engine is a double ball bearing true chrome set up.
My Os fp 40 with a Big Art tube muffler , same weight as the Fox version, same Zinger
xtra wide 10x6 prop and Fox spinner nut weighs in at 11.4 ozs, and this is a plain bearing
engine...so the difference being 4 tenths of an oz. less than the Fox , but remember that
the Fox 40 is a double ball bearing engine and true chromed sleeve.
So if we were to add two ball bearing to the Os Fp 40 we would be looking at roughly the
xact same weight.
Both the Os and Fox want to run the same way out of the box, in a fast 2-2-2 style.
With a few simple mods that I've done to the Fox 40 Deluxe I get a powerful and smooth
engine and a 4-2-4 stunt run..
