I believe that problem was on the V1s, the V2s i have dont seem to have the same problem.

Also that control type is tank steering effectively. its really hard to be accurate using that system. For example, if you want to go straight down a line, you need to accelerate both sticks at the same rate, and hold them both fully up.

Theres then an added problem of adding a weapon control which is why many use one stick. And also in order to drive that way you need to do the mixing yourself in your head, often itll lead to a very binary and inaccurate form of driving style. My using the mixing included in the transmitter, its just one less thing to think about whilst driving.

Its certainly doable, but its likely to cause more problems than it fixes. You could certainly try learning that way, but its less of a headache to not do it - the driving comes more naturally
