Is the micro servo in the store HDD or still the standard version. I remember reading a thread where DJ said new ones were available soon. I don't want to order if they are not the HDD versions.

I don't have a 7.2V NiMH to test with, but could you try using a 7.4V LiPo instead to rule out the battery? I have no good reason for this change, it's just the only difference that I can see.
Worth a shot @Jeremie... i will swap out the nimh for a 7.4V li-Ion i have... will report back...

Jer, I’m guessing Richards hdd’s were part of the batch with potentiometer. Some of those servos just burn out immediately, like the two that I had. Because the potentiometer tries to move the servo past the stopper and poof smoke. There were also posts on the forum with a few jd’s where hdd servos poof’d because the joint would bend to the stopper. It’s one of the rarer outcomes of the potentiometer hdd issue with that batch. There aren’t many from that batch still around. Richard most likely has a bunch.
Ok... Good news after an experiment (sort of)... servo number #5 from a mixed batch of 20 hdd servos I bought on 2 separate occasions has worked flawlessly for over an hour including holding (under continuous load) for 15 minutes a water bottle... 30 minutes using a 7.4v Li-Ion and 30 minutes using 7.2v nimh... Anyway this servo seems robust... So it looks like not all of the 20 servos I bought are doomed to fail... Just unfortunately I can't tell the difference until I use them...
