Possible bad batch of Sanwa servo's

[Jampot]

As title I have found 3 servos with what can only be a faulty spline pitch!!

The way to test if urs is or not is with an alloy servo horn!
Yokomo hudy these types which don't have a cut in to clamp it up!

The plastic horns work fine it is the alloy ones.

I have 2 971's (waterproof) and 1 sdx801.

I have a friend with a 971 with the same fault to.

These servos are faulty contact ur shop or distributor

in what way are they faulty?

if plastic horns work fine and clamping horns work fine then is it not possible its the horn that your using?

[Pacman]

I agree, sounds like it's the alloy servo horn which is incorrect.

I have 2 older 801's and 1 brand new 801 that accepts the selection (5 hudy horns) (3 yokomo horns) no problem.

I will only post what I know for fact

And yes the plastic ones are fine it can only be the toothsome pitch as they have the same amount of teeth and on a vernier are the same size exactly!

I have a SDX-801 in my M05, and that has a Alloy Servo horn. Goes on without problems. That is a tamiya horn though, for the M05.

Yeah I have a few that will accept the alloy horn,
I have a few that don't these we're purchased within a month hence I have said

"Bad batch"

I have only brought the issue to attention so u can check being honest if urs accepts alloy horns it saves hassle of getting it replaced.

If u are never gonna use an alloy horn it won't ever matter that it don't fit them.

It would be nice to know how many others have the issue, a guy in Australia has one with an issue (on rctech too)

The 3 with issue's were purchased feb and April this year. If u have got one this year it's worth a check
