Mi2 servo arm

[Andy68]

Im fitting a new servo to the mi2 and have noticed the servo arm has no splines inside to fit onto the output shaft on the servo , so is it the wrong arm ? or just worn out as even with the securing screw its still easy to turn the arm with no servo movement ,

could it be you have fitted something like an Acoms horn to a Futaba splined servo or it is one of those horns where you fit a conversion ring onto the servo & then fix the horn onto that.

Hi mate thanks for the reply , Irrespective of the spline size / type the thing thats confusing me is the arm itself , ive fitted many servos over the years (in model boats ) but havent seen this before , It looks like the arm that came with the kit , In your post you refer to a conversion ring , never come across one of those , where can they be bought ?

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

Having recently bought the car it came with a dodgy servo , so a new one was ordered , when i took the old one out i noticed the same issue with the old one , i lost no parts when taking apart , is this the kind of thing you guys are refering too ?
