Hey BIGMIG, I learned about that battery thing the hard way, I placed aside the high voltage batt and I'm sticking with the stock batt till I get a better batt with the same voltage. I checked all the soldering and none of them were bridging, so I guess the problem is really in the communication bit.

Thanks for the help

Oh and I pm'd you bout those crystals, I still can't find anyone here who sells crystals or any other spare parts for the HL tank.
I know there are guys on here who are from the Phils. who have some parts to spare but I think I'd better take your offer
