DJ6 controller better than expected. Works perfectly and shipping was very fast. I've seen reviews from other sellers that said the TX frequency was advertised incorrectly, but this one is spot on. That's 2.4GHz. Not 900 MHz, not 5.8 GHz, but the advertised 2.4 GHz. Best of all, I'm flying my ATV again! I will definitely buy from this seller again!
