Brian, I ran the crt.5 again with the 10L and maxamps 3s 4000 pack. I hooked up the eagle tree to it and found some interesting numbers. Apparently the 4000's are not really 20c, more like 10-12c. Disappointing to say the least. What do you think, here is the graph. 64 amps and the pack voltage drops down to 9.7! I thought these were supposed to do 80 amps continuous, 120 amps sustained, and 200 amps burst...
