CRC Generation X - LiPo Setup

I ran the SMC 3.7 LiPO/13.5
in my GenX yesterday for the first time. It's an absolutely amazing car,
but with the 3.7 LiPO, it's even BETTER.

We've had the same layout down for quite some time, so it's easy to
compare lap times from previous weeks and see what's going on...

With the 3.7 LiPO, I went from 830 grams down to 672 grams. I can shave
a few more grams from that because I made the wiring heavier than
necessary to make it very easy to switch back to 4 cell NIMH if I wanted
to.

The ONLY change I made to the car setup at first was to back off the
shock spring collar a little, to get the car to sit level. No other
changes for the first run. I immediately was able to match my best lap
times that I ran with the 4cell/17.5, but I noticed that I could run
fast laps MUCH more easily and consistently. With the 4 cell setup, I
needed to drive the car hard and tight to make the good laps, with the
LiPO/13.5 it seemed effortless. THe printouts showed my best lap, best
5, and best 10 to be jsut about identical to the week before with 4
cell, but the mistakes just werent there. I gained THREE full laps on my
good runs without actually going any faster... just more consistent good
laps without the ruhn-killing mistake laps.

The car DOES feel different... but a GOOD different in my opinion... It
reminds me of the feel of a mod car from back in the early to mid
1990's... Sort of edgy, sort of nervous, but get used to driving it that
way and you're going to be FAST. I wound up qualifying third on the
grid, right behind Donny Lia and Rob D, so that's some pretty good
company to be in...

IN the main, Donny's best lap was about a tenth faster than mine, but
his best 5 and best 10 were right on par. He turned his best lap in
pretty early in the run, mine came near the middle. I had a solder joint
fail on me so I DNF'd but the car was GREAT and I felt like the driving
slump I seem to have been in for the past several years has lifted.
