I've got a new and fairly robust gaming computer with a yokestick. I recently purchased Flightgear 2018.3 and I can't get off the ground with the Cessna 172p. Hitting 'b' does not release brakes most of the time. Nor does using the , or . do anything for differential braking. On the few times 'b' did release the Cessa veered off to the left and was not controllable. Not sure if the problem is my PC or lack of knowledge. I'm not exactly a newbie to flight sims having had earlier versions and didn't have these kind of issues. Sure could use some directions to a location where I can find some basics that work. I did look up basics in help for this version and nothing worked to release the brakes.
