ill have to say u got a good one if it holds,peel the sticker off the front of the gyro and can access other pot screw, i turned bout 1/4 turn if that much, and it started to hold at 55%hh, and at 25% rate and sero arm dosent move like before, its a little better and will hold, but i just still dont trust this gyro, bout cost me couple of times already, so i think i going to suck it up and guess go with a 401 or any other sugg. on a gyro
