New plane? Check your radio operating voltage to prevent brownout.

It is always a good idea to check the operating voltage of your radio with any new plane as the BEC may not be supplying the voltage you need (having experienced a couple brownouts myself due to low BEC voltage). The new electric servoless retracts will create a fairly high demand on the system and it was during gear movement that I experienced the problem ( verified post mortem with a RX volt meter). After testing a few other planes we found many of the ESCs with built in BECs could not supply reliable voltage. In all planes that had ESCs with internal BECs, we added separate BECs and the voltage measured much higher and could handle all demands from the radio and retracts.
This is the simple meter I test my radio system voltage with. Hook it up to any spare channel or use a Y harness and watch the indications while you cycle the retracts. You might be OK or you might be shocked. They go for very cheap on eBay (less than $5 delivered). This particular brand is Tower Pro but I'm sure there are others.
