Maxxdude: I have the Spektrum DX3, which I don't think has that feature.

Sylvester: I thought I heard there was a programming cable, but when I looked, I only saw the Castle link. I just went there again and saw the one for BK in the controllers section. I must have looked in the "motors" section before for some reason, which only lists the Castle link. Doh.

Something else I noticed, but not sure if it's the batteries. I also have two 6-cell packs that I was using and it seemed to reduce the speed to about what I'm looking for, but runtime was half of what I had with two 7-cell packs. All four packs are GP 3300 cells, but the two 6-cell packs are packaged differently. Does it make sense that runtime is reduced using a lower voltage? I would think that a lower voltage on a relatively constant motor resistance (impedance not included) would create less current, increasing runtime.

Assuming 1.2v/cell (I know they start out a little higher), what is the minimum number of cells recommended to use with the 8XL? For max cell count, it seems like 18-20 cells will keep it in the 45k rpm range, but that would be wayyy too fast for me. 14 cells equates to 31,500 rpm.
