Re: [2016] Chairman's Preview Week 5
I think the analysis for Hub City is pretty dead on, although I think that 2158 was missed. They are a strong contender for Hub City RCA since they've won RCA previously (2012 Alamo) and they've won...

Re: Top Chairman's Award Teams in your State
418 won the RCA at 2009 the Lone Star Regional. It was the same event that Bert won WFFA.
So definitely worth mentioning, even more than before.

Re: Dynamic Brake/Coast Modes?
Virtually no current passes through the brake/coast jumper.
On the Jaguar (I cann't speak for the design of others, but I can for Jag) the current involved is that in charging the MCU's GPIO input. ...

Re: Dynamic Brake/Coast Modes?
This concept has always bothered me, a bit, for a couple of reasons:
1. On the Jaguar, the BRAKE sensor pin (middle one) is a direct input to the MCU which has 3.3V IOs (which are 5V tolerant, but...
