Problem starting motor

[davidern]

Hi,I have a Phantom with Zenmuse and everytime I try to fly I always have this problem: red light blinks for 2/3 minutes and there is no way to start,then I have to disconnect and riconnect the battery once or twice before I'm able to start the motors with my radio.
Thank's for suggestions

Don't try to start w/Red lights on. Wait a couple of minutes until you see a string of greens and a flashing green light.

I just tried again right now: I have two Phantom in front of me the first one blinks red for minutes and there is no way to even start the motors,then I move the battery to the next Phantom and in few second I already have at least one green light then I wait one minute and all the satellites are connected.I'm using the same radio...could be the problem in the radio? I'm sorry but I'm not familiar with electronic and staff like that so a friend of mine set everything
