Normally you would never use negative values for the gain.
You only check the proportional box if you want to control it with absolute position - eg with a dial or a shoulder-lever on the radio.
And for power-up, it will normally hold off the initialisation until it is still so it should be OK. If it keeps moving it will abort after about 40 seconds and revert to the calibration data so it will in fact initialise on a boat or whatever. It needs to be properly calibrated for that (which it should be pretty close already).
THANKS JC ....LIGHT GREASE paccked into the servo gearbox does get rid of a lot of backlash ..alowing more gain ..but be carefull its easey to overload the motor. question JC .....ON start up roll cranks over about 10 degrees . left down ....and i have to bring it back to level with the stick. how do i correct this please ... also.. is it best to start up in fixed mode ie locked ..or start up in stablized mode .. cheers trou
It is most likely that your resistor pack is way out for the servo. Never fear though : the G-Lock has a trimming feature. Once the servo has settled at the 1- degrees left down, select the axis in the G-Lock software and click the 'Set' button in the 'Stab Servo Trim' box and then write it down to the G-Lock.
I don't remember if you have a variable pot on there or two resistors. If it's a pot, you are better off adjusting it instead of doing the trim 'Set' as I described above. What you need to do is let the gimbal initialise then adjust the pot until the 'Servo Out' indicator bar goes to zero.
The G-Lock actually auto-trims this output but has a limit of +/-20% for this trim. If the pot is way out then it can't go far enough.
I would normally start up in fixed-position so it stays at a known angle until the radio is turned on.
Not yet .......im working on a 3 position focus thingy .. using the 3 pos flap switch . and a sailwinch servo ...pos 0 infinity pos 1 some what less ..pos2 even closer .. BUT ALL PREDETURMINED. and speed controlled .. start with pos 1 and adjust servo gear to the middle focus desired...then travel adjust pos 0 to infinity ... then travel adjust pos2 to ur closest focus required .. DX8 has servo speed control .. servocity has great ali servo hubs for mounting gears on .. this is a good fix for the slopy roll gear on an AV 200 ... THINK ITILL WORK JOHN
