Our field has been in an up roar about 2.4 lock out problems. Three giant scale planes have been total loss. After looking into it, a couple may have been related to voltage issues. We did some testing. With a fully charged A123 at 6.6 volts running though a JR switch and a short extension, all were 22 guage, with a 2 amp load from a standard field checking device the voltage dropped to 4.7. With the A123 plugged directly into the load checking device the voltage dropped to only 6.1 volts. Now imagine what 8 5955 servos in a snap roll might do to voltage. I would be interested to know how many people have lost a plane due to lock out and was using a power expander like a Smartfly. I know that on my 35% with 2 power leads going into reciever from an A123 the voltage drop was around 1.3-1.5 volts according to the Hitec telemetry. This was on the ground with all control surfaces fully flexed. I added 2 more battery inputs by soldering in leads to two more servos. Now the most I see is maybe a 0.3 volt drop fully flexed. IMHO some, not all, lock out problems could be set up issues and not a 2.4 link failure.
