I just bought a DX7 radio complete with servos, receiver, etc. My question is twofold:

Question 1: Can you use futaba servos with the DX7? I know you have to use the receiver to get a match with the transmitter. Someone told me if you broke the tabs off the futaba servos, they would work.

Question 2: I use a field charger (hobbico) to do a quick charge on my futaba equipment sometimes. On the DX7, the Positive and ground are reversed, so
I'll have to make up another cord for the transmitter. Is it the same for charging the battery in the plane? Or are they all standard?

Thanks for any help, I'm fairly new to the hobby.
