I have just the standard Spektrum in my 3pk. I cut the arial on my receiver down to 4" (still longer then the minimum 3.6") and I sometimes get a similar problem. I will be driving around and at some far points of the track it seems to loose signal and the failsafe kicks in. I have put it down to the arial being too short and not enough of it is sticking up the arial tube. I was going to put on a new arial but by the looks of it you have to send it back to replace the arial, so instead I am just changing the route of the arial to the arial tube so that more of it sticks up the tube. I will be testing today so I will see how it goes.
