I'm using Tanker9x firmware on my 9x, with the original module/receiver (RF9Xv2/9X8Cv2) with the PWM/PMM converter by HK. All 8 channel wires go into the converter, and only one is a pass thru, the volume servo/pot I have made, which is on channel 7.
If you look at Page 12 on the IBU2 manual, it shows the flash meanings....so I'm not that bright to think of something new.....but thanks for the thought.
I've set the voltage at 6.1 volts for the cutoff....a little low for LiPo but since I've been using NiMH mostly lately, it is a little conservative.
So I ran the battery down again, and this time it all worked as you said. The tank started bucking, like a car running out of gas, and then all the lights started blinking, which slowly diminished to nothing.....very nice.
And the loss of all those PWM cables would be nice in the panther, but the modules are pricey (more than the radio), but perhaps there will be a sale?
I'm currently putting my second Hooben T55A together, this time with the metal gearboxes, and wondering if the 5 amp sabertooth would be okay in this one?
