I have been trying to set up the Milviz Baron for the past few days. I found it to be very over sensitive to rudder and brake inputs using Saitek Rudder unit. No matter what I did, the thing was all over the place during taxi. Note that I have been using the EZCA profile that was prepared by Milviz. After purchasing The Opus weather program, I decided to Turn off the EZCA setup and try out the opus camera effects. After setting up a Camera, I started a test flight to check things out. I use FSUIPC for setting up all control inputs and had the rudder and brake controls dialed all the way back trying to control this beast on the ground. To my surprise I noticed it took much more input (almost full deflection) to get the brakes or rudder to take effect. Also note that in testing I had set the realism setting in FSX to Easy.
I returned all the Slope settings in FSUIPC back to 0 and changed the realism settings to realistic and sure enough, the control problems were a thing of the past. The other thing that I noticed was that the nose drop experienced during braking was much more realistic. I have not tried this on any other aircraft at this point. I just thought it was worth letting the community know. I quite often see threads with similar control problems. It seems like at least in this case EZCA was doing to much!!
