The actual weight of the speed controllers will be changed on the website to true values .

one weight with wiring and the other without.

Will a Jusstock esc run 1s with a booster?

yokemad

Hi All
One of my club mate Recommend me to use software 211 on my Xtreme stock, Just Checked my speedo, V930 stock loaded and havent got 211 on options ...
What are the differences in between ? how can I go back to 211?
Orca rx2 13.5T wired to xtreme stock...
Thanx in advance

what FDR should I be aiming at for touring car with or without boost?

I have a Xerun ESC with 4000kv motor.

thx!

COBRARACING

the only difference is the new 930 has a less sensative sensor port thats all Better for the high current low turn motors less errors or going to a sensorless mode with a slight change in sensor signal .

scoop

There is no definitive answer to that due to other variables but I would start about 6.5 unboosted and go to about 7.5 with. As a general rule you want to be topping out as you want to break for the end of the longest straight. The joy of the boosted is that you can change so much without fussing with the pinions. Just watch the heat

Just wanted to know: in stock 211 is timing acc/slope (15) only for boost timing or for both boost and turbo timing as well? Want to figure out until many rpm will it reach.

COBRARACING

Justock,xtreme stock and Xerun 120 amp 2.1v or 2.0 can all run as a 1s compatible esc .

You have 2 options

1.you use a booster directly connected to the receiver port from esc ( i recommend quality boosters like Novak none of the cheap ones that burn on plug in .

2 You use a rx pack plugged directly into the battery port of the receiver but you must cut the + positive wire red on the reciever rx port (you can put in a plug of some sort to connect it later when not using the esc in 1s and what to go back to using the bec or you can have a small rx plug as a harness in between the esc rx port and the receiver to eliminate the positive wire n that short section between esc and receiver so only in reality the signal wire and the negative which is not really being used will be connected only .

The switch on the esc must be switched to on for the esc to operate .

Also turn off the lipo cut off .

ACC is for boost and its value is rpm and it work in conjuction with boost start rpm so for example

Example 1 Boost Start RPM = 4000 Boost Timing Acceleration =200/degree

Speed（RPM）< 4000 Timing 0 step
Speed（RPM 4200 Timing 1 step
Speed（RPM 4400 Timing 2 Steps
Speed（RPM 4600 Timing 3 Steps

Example 2 Boost Start RPM =9000 Boost Timing Acceleration =400/degree

Speed (RPM) < 9000 Timing = 0 Step
Speed (RPM) 9400 Timing 1 Step
Speed (RPM) 9800 Timing 2 Steps
Speed (RPM) 10200 Timing 3 Steps

Example 3 Boost Start RPM =12000 Boost Timing Acceleration =600/degree

Speed (RPM) < 12000 Timing = 0 Step
Speed (RPM) 12600 Timing 1 Step
Speed (RPM) 13200 Timing 2 Steps
Speed (RPM) 13800 Timing 3 Steps

examples how it ramps up



Turbo slope is for turbo only and is measured by steps in a time sequence.example 18 steps/0.1secs means it will add 18 steps every 0.1secs of time until the setting that you have in place is reached say 36 steps will take 0.2secs to reach 2 x 18 steps at 0.1secs that you have in your chosen setting .etc you can also have the turbo timing to reach peak asap on full throttle it depends on what you want and what you want to achieve

I thought ACC was rpm/degree!!

M7H

Cobra made a little mistake there, what he tries to say is the following.

ACC, is for boost and its value is rpm/step example ACC 250 means it ramps up 1 step in timing every 250 rpm, etc...
It starts doing this when the set boost start rpm is reached.

Hello, i have a question for Cobraracing:
I have a cirtix inspire and cirtix stock. The stock have some fets melted.
Can i use the top board of the stock (with the sensor) to mount on the cirtix inspire?? Have the cirtix inspire the connectors to mount? Will work as sensored?
Best regards

Cobra, using the same motor (17.5t xerum) would not be correct, the timing of the start, 350 to 3000rpm in ACC
6000rpm in acc 250
that is, one comes later, the smaller step size, for 350 in 3000 to use 40 of timming, begin and end in the 3k rpm 17000; If you enter the acc in 6000 with 250, finished in 16000 rpm.
In this case, with this engine, it would be correct?
Today I run short on the track (on road), with 7.98 FDR / timing 40 / 15 turbo / turbo 0.3 slope / acc 300 in 6000rpm start - with the new version of 211. (esc Xerum 60A - motor 17.5t Xerum)

Tks.
