I'm the same. I've had my MCG Pro MkIII for 2 weeks replacing my trusty X52 Pro. One thing I've never been able to do in DCS was refuelling. First attempt with the MCG I took on 6000 lbs. Every practice since has been successful, with a few disconnects. I always felt the sloppy middle of the X52 was hurting my formation and refuelling flying., but as I have average flying skills, I didn't want to blame the hardware. I was very surprised at the immediate improvement after only a few hours general flying with the MCG. Refuelling is still challenging but I finish each session barrel-rolling the tanker rather than shooting it down in frustration
