Car keeps glitching.

[Michael Long]

I have a Transformer car Bumblebee and it keeps driving then stops drives then stops and it's range is less than 1cm from controller antenna to car antenna. I am using the right crystals (checked many times) and my batteries are fully charged(Tried 2 sets of fully charged batteries). And I've seen the tutorial made about inductors. I don't think it is the inductors, this happened when I first got the car and it fixed itself automatically(I threw the car up in the air out of anger and it landed and worked), now I try driving the car again after and I haven't driving this car for more than a year because of boredom. Anyone know what is wrong? My Hummer, Ford, and Nissan work fine with the same controller and the number 5 crystal. Plus my friend had a problem with his Barricade(It did not drive at all) and he returned it for a new one.
