Hi everyone- I built a small ASV using BR T200 and Basic ESCs. I normally use FrSky RX/TX but this time I decided to try out the FlySky i6x because it’s so stinkin cheap. The ASV runs fine in manual RC mode, but I can’t figure out how to configure the i6x so that the motors will operate in forward and reverse. Right now I can only move forward using the TX. In loiter, my ASV will use reverse thrust. Anyone done this before?
I’ll start off by noting that we don’t deal much with radio stuff, so it’s possible you’ll receive better / more complete advice on the general ArduPilot forum.
Our Basic ESC expects servo-style PWM inputs with a pulse-duration of 1100µs for reverse, 1500 for neutral/stopped, and 1900 for forwards. Single-directional controls just have the low value as neutral/stopped, and the maximum value as full throttle, which may be what’s happening here.
From a brief look at an online Fly Sky FS-i6X Instruction Manual, the most promising looking features (to me, with my limited understanding of such systems) seem to be
endpoints, which I expect need to be set to 1100 and 1900
trim, which should maybe be set around 1100 or 1500 (or 0% or 50%, if it’s done as a proportion of the output signal)
subtrim, which should maybe be set around 1500 (or 50%)
