Default BAD BATCH OF SANWA SERVO'S

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

Using a 23 tooth spline arm? Not a 24 or 25?

I too have a faulty one, I bought 2, one is perfect with my hudy alloy horn, the other ones isn't, I have also tried another alloy horn on it, and it wouldn't go on either. However the plastic on does.

Any idea how I can go about getting this sorted?


Regards

U need to contact ur country's distributor mate, or message the shop u purchased it from.

It's should get sorted quickly u will be asked to send the servo back to them. I would advise getting it sorted as it's not a cheap servo!!

I have 2 others which are perfect but it seem a minor quality issue has slipped through!!

Yes 23 tooth horns ;-)

Ah OK, just checking. Hopefully it's a limited issue, I assume they will take care of it.

The big issue is they don't know there response is

"We know of no fault"

I have posted every where in an attempt to get people to check it should happily accept alloy or plastic. If it doesn't accept 1 of them it's faulty!

I have 3 servos at 250 I can't use out doors with alloy horns!!

Some Sanwa servo's are hard to get the arm on, did you try to press it on with the screw?

you will feel it go, if it doesn't then its truly faulty.

Yeah tried everything to get the fooker on! Even all my weight in pushing servo down the horn... It's so strange as down to the micro it's the same size same amount of teeth as ones that accept the alloy horns!
