Default Hitec HS-225MG and 6.6v A123

Hi, I've searched a little and found some opinions about this but I felt I'd ask again for more current opinions.

I'm planning on using a HS-225MG for the throttle on the 1/4 scale cub I'm building. I'm looking at going with a 6.6v A123 for my flight battery and was wondering if I should worry about any problems since they're only rated through 6.0v. I don't really want to put a reg in this plane.

. Servo - Operating Voltage Range - (Hitec) usuage with NiMH, Lipol & A123 batteries.
"20Jan2012:
A123 Update
"Any Hitec standard size servo can be used with unregulated A123's. - Mike."

Not withstanding the higher the voltage, the higher the servo speed and shorter overall life of any servo.

Much more information available under sub section:
"Servo - Alterations, Calculators, Databases, Leads, Repairs, Convert to an ESC or winch & FAQ."

I run all my Hitecs (probably 60 of them in service between 12 airplanes I fly) on 6.6 LiFe chemistry. I have 225BB & 225MG running every weekend on 6.6v with not a single issue. Juts my 2 cents.

A "6v" rating means its good for 5 cell NiCad/NiMH

It will be fine on A123

I have now had 4 out of 4 HS225MGs fail. My advice is don't use them on a critical control surface. Throttle is OK. I don't know for sure that my failures were related to voltage, but I was using a 5 cell NiMH pack in each case.

Unusual to have so many stop working if not age related, the following might assist with diagnosis/repair:
. Servo - Burnout. Cause & Prevention
. Servo - FAQ : Metal Gear Servos - DIY Repair & Extend MG Servo Gear Life
