Futaba FASST Review
I read that. I never get the flashing green on power up of the TM-7.

Does anyone else with a TM-7 get the same result as me?
Did you get through as yet? I would suggest calling Futaba directly if you are have unexplained issues. If you are having trouble linking the reciever get them to change it, don't risk loss of an aircraft.

With all this fuss about 2.4GHz systems shutting down at low voltages, I thought I'd do a quick test to find out for myself. I just tried the TM-7/R607FS combo with a variable supply on the RX. I started at 4.8V and had control of the servos down to about 3.10V. The servos were slower at this voltage but no surprise there. Things go South quickly below 3.10V. At 3.00V I had almost no control. Between 3.10V and 3.00V the servos became very sluggish in a hurry.

Control was re-established immediately when the voltage was increased near to the 3.10V threshold. The one caveat in my measurements is the accuracy of my voltmeter which is not traceable to NIST.

A day without sunshine is like ...night.

Most electronics use 3V logic now - they would be using a low drop-out voltage regulator and so that measurement makes perfect sense.
