Has something changed between r416 and r429 regarding the altitude PIDS?
Ive upgraded FW from R416 to R429 and loaded my parameter file and have noticed the moment i switch to DVH mode and either climb or descend my Hexa bounces up and down similar to Mennos PID tuning video. If i change back to r416 my PIDS are locked in. On R416 the only parameter ive had to change from the default is Tilt Rate D, all other parameters are default.
