V-Tail question.

[ZRX Doug]

I'm building an aerial photography plane based around an old "Gentle Lady" wing, and I'm planning to go with a v-tail configuration. My question is, how do I calculate the size and angle of the v-tail surfaces?

I've done this to a few 2Ms and larger for AP.
Works well.
This is a GP Spirit with the Charles River vee-tail mod..which carries an Aiptek at times, slung under the left wing..
