A few enquiries about this, so here goes
You already have the easy steering of a GV with the Pedals on the rudder axis
Getting the Toe axis to work for the GV accelerate and brake is possible. Before I start, the downside is you are going to change them from analog axix to a key press functions. So keep off the toes when the radio bar is active! You also need to be using CH Control Manager for your Pedals
Remove the analog toe brakes assignment for aircraft in the AH Controller Map. We will use the default C and V keys instead
Remap GV Accelerate to V
Remap GV Brake /Reverse to C
Using the CH Control Manager in Map Mode
In the CH Map uncheck DX Mode on both Toe Axis's
Set right Toe to 1 increment and enter v on both inc and dec
Set left Toe to 1 increment and enter c on both inc and dec
Please note that increment 1 has a special function that makes the toe work as press & hold until released, So once at the speed you want just release the toe.
The range sight used to be mapped to C and V so remap it where ever you want. Currently I have mapped it to my CH throttle axis instead (in AH Mode 2)
Initially I cleared the WSAD GV keys and used A and D for the range sight instead - That works to
So now you can use your Toes in both aircraft and GV's
If we ever get accelerate & brake/reverse with an axis option in AH you can forget all this and go back to use as axis
