Sorry bit of a long post.
I installed the front shocks and changed the rear spring cups to something shorter. This allowed me to get the ride height correct. Turned up the
BEC to 7.4V voltage - the fan screams and the servo is a bit snappier.
Except for the front shocks and electronics, it's been <$10 parts. But I'm starting to have doubts. There are so many goofy things, with this car, missing screws, wrong screws, Frankenstein parts, I'm starting to think a clean slate might be a good call. The problem is that it's "almost there". It always "Just a few more parts" and I then find something else.
Seems like a lot of bad ju-ju with the B7 platform. I'm looking around for a 6.2-4 slider. Plenty of 6.3
D versions, but if I'm changing, I want the carpet version. There 6.3 kit unopened on Ebay for $500, but I think that's a bit too much. We will see where that goes.
Went to the track again. I'm still not on pace with the other guys but I'm not in the way . . . as much either. Open practice time is also different than the chaos of racing. It was much more stable and I learned some things.
First, the Flysky Noble started squawking about low voltage. I thought it was the TX voltage. Put it on the charger and 3 hrs later, the TX voltage never went above 4.2V. I was scratching my head about that and figured out
it was complaining about the RX voltage. Somehow, Disney magic or Gandalf wizardry, the Flysky Noble talks with the Hobbywing ESC and knows the voltage. I haven't figured that one out yet. But I learned something.
Also I set the cut off voltage on the ESC, which caused the problem. I set it to 3.7V, which
I thought was like a normal ESC and 3.7V per cell, but it's
3.7V total. I ended up running my battery down to ~6V (2S). Crap. That was close, hopefully I didn't damage the battery. It charged up to 3.7V pretty quickly and is holding steady. I do number my batteries so I know which one it is.
