Hmmm...I think you're on to something. If it's flickering between brake and neutral, this could be a possible cause of periodic/intermittent throttle lag...no? Come to think of it, I didn't reduce neutral % until Sat night after coming home.

I'll fiddle with it tonight and post back. Thanks Shawn!

Ah - yes. Jumping around between neutral/brake can cause some "inconsistencies" in throttle operation yes.

That's why it's always best to let the ESC do as much as possible for you, and leave as much of the radio stuff you used to do for brushed motors alone. As in - drag brake, deadband, and etc.

With almost everyone on 2.4 now and free to have radios on in the pits without worrying about interference, things can fill up in a hurry with a packed house.

Personally, this is why I'm really enjoying my 75mhz stuff right now - almost no one left on it, so extremely little interference issues and no latency.
Oh boy are people ever getting sloppy with radios on nowdays. Even if you are not on 2.4 you have to be careful. Many others who aren't figure everybody else is, so they can turn their radio on anytime they like. Despite the new and improved radio technology I'm having more problems than I ever had back in the day. Guess I need to dig out the old CB crystals... Breaker 19!

Last night re-calibrated the esc/radio, no more flickering light. I'll keep that in mind for future neutral% adjustments, and report back on the intermittent throttle cuts after tonights race.

ZERO throttle cutting issues since re-calibrating the transmitter/esc.

I think from now on I will immediately re-calibrate after every braking or deadband change.

More and more happy with this esc!

A quick question on the Core-RC batts...I notice right after a top-off (full charge), the truck is REALLY "punchy" then gets a touch softer after the first few minutes. It's still punchy (I've never run them to cutoff) for the duration, but not like the first few minutes. No complaints whatsoever, just curious if this is unique to the Core-RC cells or to LiPo in general...

Anyone have offroad settings they want to share (4wd). Also gearing?

ZX5 with a 10.5 and a 5.5.

I am getting a setup for this weekends series race and looking for a good starting point to adjust from.

Thanks

with 10.5 run your fdr around 5.0


speedo settings really depend on the track man, drop the timing to #2 and start there check temps, you can drop the DRRS down to where you like the launch

The version 1.1 (new ones shipping now) are already more suited for off-road.

The software changed was there to help some issues with 4 cell in 12th scale, but the DRRS was changed up so the lower numbers give a somewhat softer feel on take off which is better suited for off-road applications.

I would set your DRRS to 1-3 for off-road applications, middle numbers and higher numbers for on-road and oval applications, asphalt and dirt oval that is.

Ok call me stupid. How are you guys cacluating FDR.

Spur/Pinion X internal = FDR

I can't get down to 5.0 without going to a 41 pinion then.

I am assuming you guys are using a rollout calc in there somewhere?

The internal for the ZX-5 is ~2.65 spur is 78 with 48 pitch gears.
