Thanks guys for your quick replies. I was afraid you were going to say that. You see, i had to pay shipping and customs to bring them to my door... this added 40% to 45% to the original price. I am not sure if the customs here would reimburse or credit for other items. I will check but from the way things are done over here it seems to me that i am stuck with these units... Just wished i read the threads in this forum before ordering.

I wrote Duratrax today and i am waiting for their response.

But in the worst case that i am stuck with them, can anyone diagnose what could have happened with the units? it must have a logical solution that can be repaired even at an additional cost.

Thanks again
