I am inretested in upgrading my transmitter from a DX4E to a Spectrum DX6i. Currently when i fly my 4 channel plane I prefer to configure the transmitter so I have control of the airelon and thrust on the left hand control mode 4. I find this easier than having airelon control on the right. Reading all the articles on the DX6i it all seems to be configured in mode 2. Only the 7s allows mode 4. Does anyone know if there is a method on the dxi6 which allows me to use the lefthand control for the airelon without having to dismantle the transmitter. I am reluctant tobuy a 7s as its more expensive and seems a bit more complicated to use.
