Do OE 33's require tunnel or trim tabs

Waste of money. Really don't need.

Now that's what I wanted to here.

With the [Magic] 33' Image the tabs mainly were used only to get on plane. But that was back in 1986 when we were just learning about venting the prop to break them loose. When that tunnel starts to pack air she rids nice.

I dont use either on my 32, boat planes in a snap and rides as flat as a pancake!!!
