V-Tail quad help pls

So I happened to come across an APM 2.6 Controller for free. I will have it in a few days. Also have obtained a V-tail quad frame for free as well. I really want to use the board for the frame and have not been able to find reliable how to’s or much info at all. Can anyone help me or lead me on how to accomplish this? I have APM Planner as i have a Mac. It is said that the 3.2 firmware can support a v tail but like i said i haven’t seen anyone use it. There are videos of apm controlled vtails but none is saying how they are doing it. Any help or guidance would be greatly appreciated. Happy Flying!
