    Twin cat rpm questions

    Anyone ever been able to get a reading to see how close in rpm brushless motors are to each other? I can imagine there is likely alot of back and forth with one motor carrying more load and trading back to the other. Is there some ways to illiminate as much of that as possible so both are carrying the same load? This would be for a couple Neu motors on hydra esc's.

    My 3080's have been apart as much as 2k rpm according to eagletree, but thats because of hard turns, hitting troughs and launching, coming back in at different angles etc. Most of the readings are within 300 rpm avg of each other which in my book is quite fine, the closest they have been in a single run is 160 ish and change, that was glassy water. It would be impossible to get them to run exactly the same rpm.

      That is much bettor than I had thought and expected differences in corners and such. I was just wondering if "buss bar" type setups where power is shared between both sides is best.

        The only way to get the props spinning at the same exact speed is to run both props off the same motor.
