RE: 6V Receiver Bat Charge
Man this is an argument that won't die. YES you can use the Futaba wall wort to charge 6 volt receiver batteries. I use mine to charge both an 1100 mah AND a 1700 mah battery. It does take longer but who cares if time is not an issue. It takes both batteries up to FULL capacity and seems to charge them better than the fast charge. I actually prefer it over the fast charge and just make sure I have enough time to charge them. The 1700 mah will be on charge for about 20 hours when it's very low. Usually I don't come close to using all the capacity and only need an over night charge. I always check the battery at the field under load and it lasts all day long never going below 6.25 volts.
