JR DS 8917HV - problem!

[Malc1]

I was playing around earlier with the Whiplash and a bluetooth unit for the VBar and noticed that something didn't quite seem right with one of the US model JR8917HV servos on the cyclic's.

Every so often the servo would just stop altogether and moving the servo arm would then make it work again.

Initially I could only get the servo to fail a few times in about an hour of fiddling but couldn't take a chance so got the servo tester out managed to get it to fail much more often.

Ended up pulling the servo out and stripping it down.

Looks like the coreless servo motor is knackered.
Anyone know if this part is available for a DIY repair?

If not it looks like I'll have to order one from the US as these servo's are not available over here.

Lucky save I think though but looks like the heli's grounded again.

Send it too JR for a service or replace with a 8925 same servo I think...

To back up jwatts007 - this is from the JR servo page -

" Overview

JR’s DS8917HV servo in USA and DS8925HV in Asia and European Market is the perfect choice for heli pilots who want high-speed servos and JR’s reputation for incredible servo performance. The 8925HV servo provides pilots with everything they need- high speed, the use of li-pos without a regulator!"

I'll give them a call on Tuesday to see what they say.
Don't really want it replaced with an odd 8925 though unless I really have to.

Now sorted with a new DS8917 sent out from ExperienceRC in the US.
Ordered Friday and arrived on Tuesday morning and ended up costing a little less than a UK DS8925 including the fast shipping.

I have also spoken to Steve at Macgregors who has now ordered me a replacement coreless motor so I can repair the servo I have here and have a spare. Didn't discuss them doing the repair with a new motor being £37.50.

As I have the servo fully to pieces after managing to get the old motor out of the heatsink case I thought I would give it a go.

These motors are glued in and a solvent had to be used to release it.
