Hello I have just ordered my DX7 and have a few questions.

I have a 4.8V Ni-MH 1500mAH battery with universal plug, so will the work well with the AR7000

I have standard Futaba S3003 servos what do I need to do to make these work with the spectrum receivers

Lastly I believe I have herd that the TX battery is week and needs to be replaced what will work


Thanks
