My Stug was DOA as well. Turned out the power plug to the electronics module need to be pushed in further. That is why I always suggest poking around a little. The whole return process is so cumbersome and time consuming. The new Heng long electonics are all plug and play, so changing out fried electronics has never been easier.

I only hope these new electronics are stocked as spares in the near future and Darkith can do somehting to make them IR Tamiya compatible
