Has anybody else besides xenom0rph who own HB 1.0 exchanged the arm with jackhammer?
I wonder if his problems are due to some upgrades they made on 2.0 so the arm is exchanged more easily?
Since I own 1.0 version I debate weather to buy accessory hand or not due to possible trouble with exchanging the hands.
Yes, I have version 1.0 and I bought the jackhammer arm and installed it. The old arm took a bit of coaxing to get free but otherwise everything went as planned. Subzero's video in post #381 was very helpful.
I don't think there's any upgrade in the arm area (or anywhere else for that matter) on version 2.0, but then you'd have to have both to know with any certainty. I'm not aware of anyone posting a comparison between old and new because really, who's going to buy a 2nd Hulkbuster?
