After a year and 1,000 miles, my stock controller - same as this one - has worked reliably. But I can't believe this stock controller has a 1.25 second throttle response delay. It is so frustrating. This delay can even be a safety issue when, for example, you cannot throttle out of the way of a car in time due to the delay. Any time you let off on the throttle completely, the delay happens at the time you get back on the throttle... starts, corners, etc. And based on my conversation with Hiboy, the delay mechanism is built into the controller. Please, please offer a new controller version one with NO delay.
