If you can take the radio back for full refund that'll be the way to go. If not, it WILL still work. You'll just have to learn the tx a bit on the trim and endpoint settings to get it to operate the aux functions. For the most part these are all novelty functions anyways, Like Ausf said, don't be discouraged if you can't return it. Other than turning the stabilizer on/off all the light/drive modes can be switched on the DMD/MF manually as well. Yes, this isn't practical in the middle of an IR battle, but it's there and these settings would usually be set before a battle.
