Wierd some posts have dissapeared again !!
Joe thanks for the reply although it has gone. Was going to ask you with the 2 receiver batteries you have set up i did not know you could put the second pack just into a spare reciever cannel is that right. do you just leave the 2 switches on when in operation and if one goes does the receiver just take juice from the other battery or do they both discharge roughly at the same time ??
