It might have something to do with your transmitter or rates.
Are you using a Spektrum DX5E by any chance? They have hardly any movement at all and they are slow.
I have an FrSky Taranis I use the 3 position rates @ 50-75-100% to adjust in flight control. These rate allows me to select the control throw for any flight situation. The 100% rate at full throttle may too much for some flyers. I use 50 and 75 % rates in slow flight to help new flyers transition from gliders to jets
