I picked up a b4 a few weeks ago and as I get more familiar with it I'm noticing about halfway through a pack the power seems to fade a bit. I have to pin the throttle to clear a double that I could just roll through 6 laps earlier. My first thought was glazed slipper pads so upgraded to garodiscs instead of sanding stock pads. They helped a bit but didn't fix the problem entirely. Temps look good too, 140* on the motor and about 100* on the esc. Any ideas?


Here's my setup

-Novak ballistic 17.5t with high rpm stator, 40* timing on end bell
- geared 32/72
-garodiscs with stock spur
-Novak gtb2 w/x-drive esc
-venom 50c 5000 mah 2s lipos, full size.
-airtronics mt4 w/rx-461 receiver
-spectrum 6040 servo

Sounds like normal voltage drop to me. Half way through the pack you won't have as much voltage to play with, so your car goes slower. Since it's a 17.5, it goes from slow to really slow.

Most run shorties in 17.5 to lighten up the car. But yeah it sounds like battery fade. But check to make sure everything is really free. Bearings etc

Nobody really runs shortys at my track.

I would try turning the timing down to 30deg and install a 34t aluminum pinion.
A 60c+ shorty helps a ton as well. Good luck!

B4.2

We all knew it was coming i just need the towers

Looks about the same, cool though we don't have to wait any longer for questions.

Not far from what most are running right now. The shock towers will be nice. Wished they had moved to metric hardware though.

My guess is it won't be stopping at the b4.2, a t4.2 and sc10.1 with same updates are on its way as well, so we'll see ;-)

did you notice the new carbon uppers on the hubs.... That is not the current c-hub. Also, BTW Wild Cherry you loose. There is no brand new car, just the b4.2, lol.

Are those AKA tires on the front? Vectors?

Looks like Pro-line Scrubs

wow, so many people crying about the car not being a complete revamp, lol. I dont think anyone believed it would be a brand new car. And we all knew 2 months ago that we are already running the b4.2. It will be nice for those buying a new car in the next month or 2.

ok, that makes more sense. AE and proline have been partners since the beginning of time.

I am happy its not a complete vevamp, suits me, and why change a winning platform!
