I bought a set of Align BL-8XX HV servos from a guy here on RR.
They are 3 BL-815HV and 1 BL-855HV.

I may have gotten a price that was "Too Good To Be True".
He said they were "Pulled from a new 700 Dominator kit"
https://rc.runryder.com/t798625p1/?p=6531986#RR

I am starting to see comments about these servos being trouble and I am worried.

From what I gather, some BL-8XX HV servos have serial numbers (these are "good" ) and some do not (these are "bad" ).
People that bought kits with BL-8XX HF servos without SN can send them to Align for servos with SN.

The servos I bought may not have the serial numbers (I don't know for sure). Two of the BL-815HV have the same number printed on the bottom (H1505) and the third has a different number (C1531).
The BL-855HV tail rotor servo has yet a third number (B1510)

The real question is:
Are the BL-8XX servos without serial numbers deadly?
As in "They WILL fail, they are no good, don't fly them"?

I have not even started the helicopter yet.

This is a 700N converted to the CHP direct to swash setup (similar to the 700E Dominator) with the DFC head and 715mm blades.

Would Align help me if I needed to swap them for servos with serial numbers?
If so, where do I call?

I haven't talked to the guy I bought the servos from, so I don't know where he bought his kit.

Thanks.

I had a none numbered set on a 550l and tried getting align to replace them after one died and aligns support was terrible saying they are only replacing them within 60 days of purchase.

"Non Numbered" - as in no numbers on the bottom?
Or all having similar numbers (H1505, C1531 or B1510)?

I guess the next question is:
What does a BL-815HV serial number look like?

Hey buddy.

Don't worry your servos have the serial, the number under the "Made In Taiwan" is the serial. On one of your servos I saw it read "C15XX".
I had a set of the previous release which didn't not have this serial number and according to what I know it's this small number under the made in Taiwan you're looking for.

OK
So it is not a typical "Serial number". It is more of a "Batch number".

Does than mean the "bad servos" didn't have any numbers printed under the "Made in Taiwan" label?
