You can set EPA, but Gear Ratio should stay unchange.
This is what I don't understand.... People, Don't get the 3.5R because it's the same price as the 4.5R, 5.5R....10.5R... You should know what you use the motor for. Besides, pure speed doesn't mean anything without good setting and driving skill. As I mentioned before, the most popular brushless here in the USA is 10.5 and 13.5. 10.5R race with 19T, and 13.5R race with 27T. |
