"SOLVED: I feel silly :) I started triple checking everything from the start, and realized that my rear motor was set up to spin CW, not CCW like I had thought.

It's literally the worst thing to have to change on this Trifecta frame, requiring me to…"

"Having the same problem with a new Tri build myself, and not having a very easy time of finding info on the "correct" way to trim it.

Is there even a manual for tricopters using APM anywhere?"

"Another option people have tried is to attach a bluetooth serial tx inside/on the TX module, then you can connect via bluetooth to your tablet/computer to eliminate the cable."

"I just used a couple zip ties to attach 4 ESCs to the left and right side of the rear arm, it's worked great and keeps them out of the way so that the front arms can fold back (I live in NYC so have to travel with my copter to fly it).
