I didn't change my sim speed. To be honest I don't know what that actually does. My settings are all standard. I'm just using an old Futaba AM tx and I'm not using expo or anything in the setup. I have a Futaba computer radio but the interface doesn't work with the trainer plug so I have to use my old AM radio. Sorry I can't help more. Maybe someone else can help. Stick around for more replies to your thread. I've heard of Pebble Creek. They have a buy-in membership from what I heard. Supposed to be a nice field. I fly at the Flying Electrons Club in Menomonee Falls. In fact I was just there last Monday flying. Not too bad out actually.

Good luck,
Joe
