Streight out, I am a frustrated buyer and attempted user of the OMP Sim. Purchased the delux unit January. Called middle of February asking status of delivery. Unable to deliver due to back order of controller, due in next week. (Billed my account first day) Waited the week, now back order several weeks away. Ikrus says May. Ok, send me the package less the commander for JR. Got it last week, and working to get it to work every since. Everything works right out of the box except the controller. (the one they do not have) Tried JR 10X, JR 9303, Futaba (2). Finally got the system to recognize a controller on line and show some reaction in setup. System still says no controller connected, and still have no control. Apparently the JR conection substituted for the Fatuba Multiplex connections. Called and had the JR connection shipped (another $30.) From my view, this group just does not have it togeather. Don's know what RCU reviewed in their lead report, but not the same complete items I received. Don't know the answer. Part of the problem is probably that I am a complete computer dummy. The other is how do I get some real on line help aka AOL, Del and other professional originazions. Yea, I am venting.
