I'm using a DX7 and love it. I had a DX6 but recently upgraded so I could use DSM2 stuff. It has a whole bunch of nice features, although I'm sure most nice radios do.

Ya I think its fine. It holds well in a hover and while flying around. Once I get into more crazy stuff I might look into a new one. I just started nose in like a week ago and can now do turns like a stall turn but at like 45 degrees not 90.

If I was to upgrade something I think it would be the motor. What motors do you recommend? I have a 35A Align ESC but if I had to I could always upgrade that too. The one thing I'm worried about is a better motor might reduce flight times. I get around 9min hovering and some FF with a 2150mAh TP battery.
