Running a hpi blitz ese and got a rx8 gen 2 and pro 2 5100kv on the way. Running a JRZ9100s servo. It might be a dumb question but I never had a problem with the servo on a RS pro only a slight lose in motor power during turns and all the leds would flash random and in no order when powered. I'm assuming the rx8 gen 2 shouldn't have a issue. Also is there a sensored only or timing boost mode? How is the interface differ from the RS pro?
