Spektrum has announced a firmware update program for their line of DSM2 spread spectrum receivers. The upgrade adds what they are calling QuickConnect, which decreases the amount of time the receiver takes to start reacting to transmitter commands after a loss of power. This is meant to address temporary voltage drops often caused by digital servos. The Spektrum website has details on the program, which requires users to send in their receivers.
Our take: On one hand, Spektrum deserves credit for listening to customers, admitting there was a problem, and fixing it. No doubt these voltage drops and the crashes which ensued were often due to pilots overtaxing the BECs in their speed controllers. On the other hand, shipping a receiver which can take up to five seconds to get back on the air was a mistake. It also seems a bit disingenuous to call this a feature instead of a bug fix. Whether you've experienced the problem or not, we encourage all users to send in their receivers and get this new firmware update. It's safer and it might save you a lot of money.

I called HH about a lost of power and control with the Spektrum receivers but they said they have been tested and it must be something else I have wrong.
The article proves voltage drops can cause a drop out and crash.
How can I tell if my receivers 12 have quick connect. I turned on radio and plugged in receiver. If I unplug the receiver and plug it in again it blinks which HH says means I have quick connect.
The electric motor will not start again until you put throttle down and than bring back up on the radio allowing a low fly crash. Is this correct? Ron
