I've now done a few test flights with the 170 and 195, both recently downloaded versions so they're up-to-date. For some reason the 170 will NOT hold speed at altitude regardless of whether it's FMS/MAN. In fact, in the video I took within X-Plane, I went to MAN mode and decreased the speed whilst the actual speed kept increasing. I suspect there may be some sort of coding error with the 170 that appears to not exist in the 195 regarding this. Please advise.
