RPM Reading TT Pro .40
Mike,
From my own Tach reading of the TT Pro .40, I got 17,200 RPM without the baffle and 16,900 with the baffle on the ground. However, in flight test with same plane (Predator), same fuel, same day and same time, same prop, the engine with the baffle seem to unload better and seem to out perform the one without the baffle by about 10mph in speed (at least that what I think from own observation). Plus, the needle setting is more consistant with the baffle in it.
