RE: Dubro servo arms color coded?
Grey=JR
White=Hitec
Black=Futaba
But don't trust my word, look on the packages themselves...
Oh yeah, don't switch them....know a guy who lost a plane due to elevator flutter (Dubro JR arms on hitec servos; not positive but servo arms were stripped). Sad part is that he trusted a guy who has been flying for 25yrs to set up plane for him (yep, experienced guy made this mistake).
