I was looking at the GT3b but was always on backorder so decided to go with the 310 to run my RC8RS. Push button bind was done first go with no issues, EPA holds position well, has good range (better than my eyesight), and failsafe works well. It also has more model memories than i will ever need. To many other settings to go through but played with all and was impressed for the price.
I am going to get another rx to try out on second Evader i am building to see how it goes with brushless system, will post results when done.
