It wasn't as tight as it looks, I did it through a few other holes that were even tighter but had to raise the drone at the end so the camera angle wasn't just right.Very close to trees and that power line. Would have been safer to record coming in and reverse it in post so that the vid played backwards.
I had it in SPORT mode.I think the reversing was to avoid the front OA from triggering and stopping the drone. I done it once with my MP, happy with the result, not planning to do that again, especially with my M2P.
With M2P, you need OA off, cos the rear OA would go off.
So in that regard, you can just fly forward with OA off. I guess the difference is if you accidentally hit a branch, you don't want to hit it with the camera.
