I am having the exact same experience. I have posted the problem on the Ikarus forum but so far no help there. I am waiting to hear from the place I purchased it from.

Also, the piccoboard arrived in a package marked JR and the shift jumper in the Futaba position. I have tried using both pos and neg shift transmitter and receiver jumper settings. When the piccoboard jumper is put into the JR position nothing happens (no jitter and no LED light).
