My son flew his Mini Guinea again today. Two instances, different flight batteries. Both problems happened mid battery usage.
First instance, loss of both motor power for a second or two, but no loss of servo control. Second instance loss of both motor power and servos for a second or two. Both problems were singular and didn't result in a crash. Also, both motors cut off at the same time, no differential thrust occurred. Motors were not at full throttle either. Batteries (800mAh 3S and 1300mAh 3S on the separate flights) were well above 3.8V per cell at landing.
Transmitter: Spektrum DX9
Receiver: Lemon RX Stabilizer PLUS LM0044 (stabilizer and plus disabled) DSMX
Motors: Current A pack twin
ESCs: Current A pack twin (Yes we calibrated the throttles) (Also, no differential programmed in on transmitter)
Possible contributing factors:
1. Both ESCs are plugged into the receiver WITHOUT the power wire clipped on the second one.
2. DX9 transmitter battery is a 2S LiPo and was at 7.3V
3. Other
What is the most likely cause of the likely signal problem of the three above? When if ever does the DX9 range lower based on the transmitter input battery voltage?
He has flown it for three batteries with the transmitter at full charge prior to these two flights with no problems.
