There are a lot of questions to answer. What was the MA of the battery? How many flights on the battery? How new or old were the switch and servo extensions? Have you cycled the battery?
On another forum there was a thread on power needs for Gs planes with hi-end servos. This probability doesn't apply to you, but it was found that a 100cc plane at idle was drawing 2 to 2 1/2 amps at idle on the runway and after a hard 3-d flight the power piked at 19amps. We also showed the the standard servo plug caused a 1/2v drop each.
On our 2.4 receivers power is everything and must be watched very closely. A 4.8v battery must be recharged when it shows 4.8 because under load it will drop lower. Same goes for 6v.
Standard servos won't have the amp draw as the high end ones, but still old wires, old switches can cause a voltage drop before it even gets to the receiver.
This apply s to all the 2.4 radio systems. Dennis
A question for you: Over the years Spektrum/JR has been known to have a brown out problem. There was a call back/ warning on the JR site about the long reboot problem with the original RXs and you could get them replaced. It was suggested that the 4.8 volt battery not be used and people should use 6 volt packs. Still, when you bought a new radio the 4.8 volt pack was included. Last new radio I saw still came with a 4.8 volt pack.
Why doesn't JR/Spek send out new radios with a 6 volt pack? I have been told JR/Spek has changed there system and is now more in line with the Hitec and Futaba in the way it sends and receives the signal?? I have been told if you have an older radio it can be sent in and be upgraded.
Just wondering? An inquiring mind wants to know. All I seem to get is rumors from the field.
