Servo question?

[Spucknit]

I've been running a Futaba S3305 with no problems until today. I installed some cvds which should if anything allow the servo to move with less resistance, and the only other change was put in a new 1500 MaH 9 cell 2/3 a NiMH battery. I was originally runnig a 2000 Mah 8 cell 4/5a NiMH. The crawlmaster/max combo loves the new battery, but the servo has lost a lot of power. It wont move the tires at all while at a stand still. I'm not runnning a voltage regulator, becasuse the BEC of the max has always been sufficient for my 2.2. I did notice something strange though. While looking through the specs for the servo it said Nicad only. Could the fact that I've been runnung a NiMH for a while have harmmed the servo? or could the fact that I changed cell size matter? or number of cells? any advice would be appreciated.

I would say the loss in power is due to you adding a cell in your new pack. The output of the BEC decreases when you increase the input voltage. To gain back the steering you will need a regulator, a receiver pack, or reduce your input voltage.
