Maule M7 by Pilot Experience Sim

I recently picked up the Maule, in a sale. Not my favourite bush plane to be sure. In my hangar that would either be the Wilga, the DoubleEnder or the Kodak. However, overall, I’m quite happy with my purchase. I’m just curious about a couple of things.

Firstly is PES still working on this thing? I tried emailing them but received no response. Secondly is the autopilot meant to be functional? I cant get it to work and if its not functional then what was the point of including it?
