"Kicking" Servos

[neuman5022]

Hello Folks

I need some help here.

My TQ is hooked to DVATX + Phidgets 8/8/8 and ServoCard.

Calibration is OK - all works fine, but everytime I load the power supply for the servo card - the servos "Kick" the handles - some times very erraticly. Lowering the handles back to IDLE and then all works OK.

Tried several load sequences - but I got the same. Tried to use the Phidgets original power supply with the servo card (I use the 12V from a PSU) - no joy.

I have normal high torque servos (not Hitech)

I also use different OFFSTES for the servos and inputs.

I am currently doing this with the FSX throttle - not with my PM setup. (MCP Etc)

Is there something I am doing wrong ?

Cheers

Use N1 offset to drive your servo's if you arent already

Hi Issac,
I dont use Phidgetsbut have had that do it to me with Cheap servos. I made a trim position gage with servo supplied from Tower hobbies, their own brand.
Every time i applied power it would jump to new position.Replaced it with a Futaba or Hitec and these didnt do it.So it maybe servo type.
Hope thsi helps.

Guys, hands down, the new hitec micro digitals are the way to go! Fairly cheap, programmable to boot! Small foor print, will fir inside a 2" gauge. Use them and dont look back! Some places you shouldnt try save money! ;)
