Default KO PROPO PS-87 FET Servo

Hi,
Is anyone out there running a vintage PS-87 servo using Lipo power?

This servo has a blue wire that you connect directly to the battery positive, but the specs on the servo say this should be 7.2V, I'm wondering if the 8.4V from the Lipo would be a problem?

I suspect that back in the day a fully peaked pack of SCRs were probably way over 7.2V anyway, but my memory is not that good and all my old cells seam to have died!

This servo is a little low on torque by modern standards, but looks fast enough, and I'm hoping that if it stood up to the abuse I gave it as a teenager, it might survive a bit of running in my recently restored YZ10.

I would appreciate hearing of any recent experience of running one of these servos.

Thanks.
