It has been awhile since I looked at what is available.
HS 82 MG are new to me.
I think they are more than what you'll ever need for a 1/2A project.
Last time I went shopping for 1/2A servos I hate to say it but the Hobby King micro servos did the job just fine and this was back when I did quite a lot of flying.
I think "HK Corona" was what I ended up buying in 4 packs, They were so cheap that I didn't feel guilty about simply leaving them permanently installed in each plane that was built..[instead of .transfering high priced servos from one plane to the next]
