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. FWIW,
I was taught to add power gradually which I do, usually anyway...

The 235 airframe has a small rudder compared the
320/360 series. A majority of 235 builders have added the ventral fin to the
bottom of the fuselage and added the same amount to the bottom of the
rudder. This rudder addition adds about 20% more surface area to the
rudder and helps significantly during the takeoff for airframes
with 320's.
Doing as you have done, adding power slowly in
the initial takeoff roll, is still required even with the added amount to the
rudder. On occasion, full right rudder will still not be enough to
overcome the 320 overpowering the 235 airframe. Particularly if there
is a bit of crosswind.

p-factor takeoff in 235/320
Hey! It works... slow application of throttle with full right rudder, then
gradually reducing rudder .
I just
pretend I'm in a P-51. : )
Thanks
to all for the suggestions.
