Mi2 servo arm

[fidspeed]

Hi Andy

i think Wolfie is refering to the large kimborough range of servo saver/arm
they had a large hole in the centre of the arm which you fitted an adaptor usually 3 different adaptors came with the kit for futaba ko acoms and sanwa spline I cant remember exactly but i think futaba/savox is 25 spline and KO/acoms is 23 but dont quote me

it is possible the splines have worn away in the arm .
daft question are you fitting a new (different brand) servo ?

hope this helps
