Cross The Road Electronics has posted a detailed report of some Motor Controller Output Power Testing they preformed with the four main FRC speed controllers on the market:
- Victor SP
- Talon SRX
- SPARK
- SD540
Link to .pdf document here
Please take note of the test results on page 7. I'm very concerned about the SD540's performance, particularly that the SD540 appears to brown out at 9.5V.
2016 will be the year of the brown out...
