Do any of you folks with the extended ventral fin  have a picture you can =
share?

Thanks

I'm another 235/320 driver that added the ventral fin that extends the =
length of the rudder.  I did not add the trailing edge full length.

So far, I've had enough rudder to maintain runway heading using the =
gradual throttle (as I too was taught many years ago).  Use caution and =
apply rudder quickly on a go around as this caused an unwanted left turn =
recently.. I blame not paying attention...seeing the windscreen fill with =
tree tops brought me back to reality!

I did as Gary described but also added 3" to the trailing edge of the =
rudder full length.
I can nail the power on take off and have no trouble keeping the airplane =
heading down the center line.=20
FWIW,
I was taught to add power gradually which I do, usually anyway...
