I've done some more research and rcmart doesn't sell the charger with the radio. If I go through tower and buy a 3 channel receiver $89, since the system only comes with one rx, I will get the charger with the radio. After adding up the cost through rcmart which includes the system, 2 rx's, radio charger through amain and shipping I will only be paying 5 more dollars by going through tower with the super saver club discount.
There are two 3 channel rx's to choose from with the only differences being port and antenna location/orientation.
The question is, does everyone use a battery pack in the radio which would make purchasing the charger necessary? If so, I think I may go through tower.
I may be over thinking this purchase.
