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?
