RE: 3PK or 4PK
I have a great radio, and for the money you just can not beat it. So it is not backlit. Wah.
You really should check out the Spektrum DX3R DSM2. The thing is bad ass, and the scroll wheel..... Oh yeah.
I thought about buying the 3PK. Just didn't like the feel of it. Keep an open mind, and at least check it out. Besaides, until April 30th, you can get a free reciever with purchase.
