Speed Runners ~ How Fast Did You Go Today?

[jondilly1974]

@jondilly1974 It seems that the speed gods always keep you 1mph below a really good number. Hey, 129 is awsome, but 130 would be even awesomer!

Tomorrow. Maybe

I tend to have the same issue always 1 short damn it!!

 

[Doom!]

What the heck kind of attitude is that?!?! You gotta want it, live, eat, breathe and bleed speed, let me hear you say it! What was that? I can't hear you!, again! Believe it.

You gonna let one measly mph beat you like a Traxxas owner? I didn't think so.....now get out there and revel in the glory that is meant to be yours!

Whoa, I think I might have been channeling George S. Patton there for a minute.

I just went back to 150's club. Not a PB but still feels good to be back and hear that sound of a screaming rc.

Nice pass,you got a great spot there...

DON'T SAY THAT... CAUSE THEN A CERTAIN SOMEONE WHO IS TRYING TO BREAK 200MPH WILL CRASH AT 199

Couple test runs with new motor.waiting on taller gears now.116 &114mph

@LibertyMKiii what can you tell me about this first log with new setup.defininity need to gear up..

@LibertyMKiii what can you tell me about this first log with new setup.defininity need to gear up..

Looks like it definitely. Great Amps and RPM is still climbing at let off so definitely a lot of room for gearing up it looks like to me

Agreed with @Edough13
looks like you need a longer run (longer time at full throttle)
gearing up wouldn't hurt at all with how low the amps are.

 

[K-BASH]

waiting on gears is the worst.gonna give tp4040-2100kv a try.i got gears for that.

 

[Edough13]

Wish me luck fellas getting ready to head out and see if I can pull any gain with 6s went up to 1/1 at 34/34 so hoping to match or beat my 8s PB of 125 and ultimate goal would be 130mph on 6s. Last runs had a lot of changes made and stayed stagnant at 123 on 31/34 over previous passes with 30/34. Changed Bec back to 6v also adjusted perfect pass to a lower delay so hoping to atleast pull 2mph more and match my 8s PB but really would love to hit that 130 on 6s. We shall see shortly

Been playing with the CH speed on the noble. 5s delay as @jondilly1974 did with his infraction seems to be ideal. I wish i could turn it off/on with a button though. Making a u-turn with the delay on is really annoying. (drove it in the ditch once) Anyways it does really make data comparison much easier with the throttle curve more of the same.

Also did a 4S run (set on 8S gearing) It's so counter intuitive that I should gear up whiles running less cells. But it's been running it overvolted so efficiency is really different.

I bet you can, just about anything on the nb4 can be assigned to a button.

This specific feature was changed/renamed during the last firmware update. It's not available at the assign to button menu (yet)
Being able to cycle through profiles would even be better. other than ch speed, i would also like to change my steering in the same action.

Absolutely Mint!!!
However, they won’t find it unless you write it in Chinese.

you might be right

Flysky Noble NB4循环配置文件（按按钮分配配置文件）至少包含CH速度，EPA和转向DR / EXPO

 

[Edough13]

Well damn it!! Definitely tapped out on 6s, dropped to 122mph with 34/34 on 6s. Looks like time to gear back down and start some 8s passes pass distance is low cause I went off the road turning around after the pass.

So my last few logs I gave it full throttle for least 2 seconds.logs said I never was at 100%....any ideas??have done 5 runs an none at 100%...Just did throttle calibration, going for 1 more run at my best spot.going for pb on this one.full send,see what happens

Odds are your not calibrated on throttle. Possibly not long enough run either but more than likely need to recalibrate throttle

I'd say 99.x is good enough.

You can see in link what ms is set of full throttle. If you reach that number in the logs at max Throttle In, your throttle calibration is fine:

It depends on gear ratio & the actual power out your at while hitting full throttle. In this example below it takes roughly 1s to hit max P out and another to hit max rpm.

If you are hard on the trigger and hit full throttle before you are >85% P out it will take more than 2s to reach 100% and max rpm will often be slightly lower.
