Has the IBU3 been discontinued, have an IBU2 pro thats having issues all the sounds are OK when using the sticks and switches. No power to the motors and the servos only work if you power the Rx with a battery pack. No obvious burn marks on board, last time the recoil servo died and you could see a burn mark. Sent it back for a fix ,repaired /replaced.

I believe the 3 usb version was a short lived expirement.

Thanks for that
Was going to buy one as you could program the unit without removing the SD card. The programming also looked a little better than on my old IBU2PRO one. Will probably buy another Elmod fusion pro again , the programming of the unit is easy as you can adjust and check functions with the tank switched on. Have to order from Germany and thats becoming a pain with leaving the EU. More hassle, taxes? and extra time thro customs.

There is a US Dealer that might be easier for you.
