I want to build the BB-R2 from Mr. Baddley. I want to use the IO-Tiny and a 7.4V lithium battery. I need three continuous rotation micro servos like the FS90R.
However, I need it to run with the voltage up to 7.4V. Will the 7.4V lipo "fry" the FS90R? Is there a 7.4V continuous rotation micro servo?

these are 6 volts servo's . i dont think they will last long .
The EZ-Robot micro servos may be able to be modified to use in continuous rotation applications. I will have to check if the stall protection activates and disables the servo after a few seconds.
Otherwise, I would suggest continuing to use third-party continuous servos with the 5V inline regulator as you suggested.
*Edit: Actually come to think of it Feetech does have 7.4V rated continuous servos. They are called FS90R. I bought them at Robotshop I believe. I've successfully used them on my Magnedrive robot.
