Well, I'm the type who does not 'blip' the throttle often enough as I am an electric guy at heart. The OS speed has really suited me in this respect. I had problems with RB's (my fault) and later G branded motors (motor fault).
I ran the G branded motors for the better of the last year & a half but had a lot of problems with flame out & carb issues. Well, sold all of them & never looked back.
This motor has helped me to move up from a middle 'B' main finisher to middle 'A' main.
Also running a Ninja JX in my truggy. Plenty of power.
