Initially, I remapped my various Honeycomb Bravo levers as shown in Rmag’s YouTube video tutorial, which has been referenced a bunch on the forum. In the Sensitivity settings, the Throttle 1 lever appeared to move through 0% to 100% quite normally and linearly yet in the sim while flying, I couldn’t go lower than about 30% throttle and the throttle on increasing would suddnely jump up from there to about 60% or 70% and be “linear” to 100% just over the last little bit of its upper range. It turns out when mapping, I must have screwed up by mapping Throttle 1 to L-axis Y-, somehow.
I went back, cleared the input, and validated to remove Throttle 1. Searched all Honeycomb Bravo bindings for Throttle 1 and mapped it by input scanning. This time I came up with L-axis Y. Moved the throttle handle from all down to all up, back to all down and validated. Now the Throttle 1 lever works great in very linear fashion through the full range of engine RPM .
