I owned a FlySky GT5. I thought it was good enough for 1/10 off-road competition. At some parts i needed to accelerate quickly to make a jump after short part. I was always hard to achieve this, i thought my esc to slow for it. One day when practicing, i asked one of the guys to use my car and transmitter to see what i am doing wrong. The thing he instant noticed was the response time was way to slow. He showed me that if you moved the trigger this far, your car should have moved already, wich it didn't, resulting pulling the trigger to far and doing to much already, making everything harder to control. So got myself a Futaba 3PV, this was huge difference.
