e-Electric Motors & Controllers > Jazz 40a still not working right? anyone?

I just reprogrammed my jazz esc last night on my trex 450 per the instructions including the supposed 10 second warm up at zero pitch so the jazz could learn my motor. i started in flight mode two which is a straight line 100% throttle curve and just flipped off the hold because the instructions say you can do that because of the slow start. I have flight mode one set at 90 straight line throttle curve and normal is set at 0, 70, 100. when i switched from flight mode two down to one i could hear an audible decrease in headspeed and when i tried to go back to flight mode two the head speed would not increase again. it seems as if once i drop the head speed it seems to lock on to the new speed and will not let you beyond the lower speed. Am i doing something wrong or is something wrong with the esc or has it not learned my motor yet. i can't seem to figure it out

When you first plug in the battery move the throttle from zero to 100 them back to zero then move the throttle up switch. The ESC must learn the throttle not the motor. With this ESC useing a 100% throttle curve is useless why pay all that money for one of the best governer in the hobby if you are going to use 100% throttle. Go up one tooth on your pinon and use a 75% throttle. This will utilize the gov. this it what this ESC is knowen for along with ath auto timing feature.

someone told me that it may be the fact that I'm using 100% throttle curve that is giving me trouble, he said it doesn't allow the governor to accelerate beyond the point being that it is already at its highest. Besides, the only reason I'm using 100% is because I can't get it to operate at any other speed once its set at that speed. Like I said, I'm new to this ESC and hence why I'm here asking for help

I've heard other people say you don't have to move it to 100% after the initial setup, but if I do, do I need to have my throttle curve setup 0,50,100. And do I have to do it fast and back off fast or go to 100% and let it spool up, please elaborate.

Your start up curv should be 0, 50, 100 Set the delay at around 15sec. set your st 1 curv at aprox 60% flat line st 2 to 75% Plug the battery in and move the throttle from 0 to 100 then back to 0 the roters will barly turn due to the 15 sec ramp up you set in. Then swithc to ST 1 the heli will take 15 sec to ramp up to 65% and will hold that no matter what you do.[within reason] then go to ST 2 it will speed up to 75% and hold

I have several jazz esc's and have never heard of having to go 0 then to 100%?

What you heard about is the "powerjazz" ...when you use "AUTO" throttle onthe powerjazz you need to do that...it DOES NOT apply to these jazz esc's though

That is not necessary...

The correct way to set up a jazz is VERY simple...first of all...you set the correct mode(heli mode is 4 blinks)i'm sure you already have this programmed...then you need to program your radio endpoints...

this is done by unplugging the motor..set a linear 0-100% throttle curve in "Normal" ...then plug the battery and esc in...so everything is powered up...then set the throttle stick to low..go to the throttle ATV screen and adjust the atv so that when the stick is ALL the way down the red led on the jazz lights up...and then adjust the ATV a few points beyond that.(led stays on)..then you need to do the high throttle setting..go to FULL stick...adjust the ATV so that the led stays lit at full throttle and then go a couple points beyond that..

Now your endpoints are correctly stored...

then set your "normal" curve so that at low stick(0throttle) it's at ZERO...every point therafter should be a "FLAT" setting...

and then your stunt modes should be FLAT as well...just move the flat curve up or down to adjust your desired headspeed.(should be in the 70-80% range

You do have the heli geared properly for governing right?

Rule of thumb is that you're target headspeed is roughly 80% of TOTAL headspeed available..this gives the governor some "Headroom" to operate in...

If you set your jazz up this way you will NEVER NEED to go from 0-100% at startup...I would instantly go to 50% though(o pitch ) for spoolup...

I actually just set up a new Jazz 55 on my Roxxter last night and test flew it this morning

JAG72 I too have 6 of the Jazz ESC's I use the program card and use the auto tho. function which is avab on all but a few lower end and car ESC's because YOU have not heard of it DOES this mean it does not exsist?????????

WOW I guess YOU NOW YOUR JAZZ Check the website and do a little reading#$#@%

jazz...

why would you ever need to use that Auto function on these anyways?

It's a Pain in the As$ if you ask me...if it's available on these smaller jazz's then I stand corrected but I don't see any reason WHY you'd go with an auto instead of just setting your endpoints in "FIXED" once and then never having to worry about it again?

Can you please enlighten me and supply the link that talks about the new programming of these JAzz's? I can't seem to find anything on this..

I have a program card also, BTW, but I only use it on my Powerjazz's ...these smaller jazz's are easier to just program with the sticks...but that's my opinion..

If you read my quote correctly

you'd see that I said it it does not apply and is not necessary...and I'm right...it doesn't apply if you are not using a program card not only is it not applicable but it is COMPLETELY unneccesary to use the auto feature...

If you start in idle 1, then try to go to idle 2, what happens? Does it idle up?
Im assuming you tried this multiple times, I just didnt see a post on this.
Try setting your curves as this.....
norm 0,70,70,70,70
idle1 80,80,80,80,80
idle2 90,90,90,90,90

and report back....
this will give a better understanding to the group as to whats going on.

Jazz should be reasonably simple.

How do you know that your raido and the JAZZ knows that 100% is what 80% is what 90% is there is a voltage differance at 100% between JR futaba and so on. When you go to auto tho. move the stick from 0 to 100 and back to 0 you have told the ESC the 0 and 100 point for your raido. Now you are 100% sure the ESC knows your raido 0 and 100% levels sure you can guess at the levels but are you sure?? This is not a big deal to me to perform the 0 100 0 upon first power up. I now have a ESC that is 100% sure of RPM I have a very consistant RPM from flight to flight. Do not go to the USA website go to the German website there they will detail complete instructions on the procedure.Then you will relize the full advantages of your JAZZ or could it be that you have a older ferm ware level you can also send them in for a upgrade if you wish

The solution is simple...you set your endpoints once and you're done...you do not have to reset endpoints unless you change radios...why bother with the hassle of going 0-100 EVERY time...downright SILLY waste of time and energy if you ask me..

Trust me ...I know all the features of the jazz ....There is NO benefit to using the AUTO mode ...I know the full advantages of the jazz and ALWAYS have consistent rpm's and flights...I use my jazz esc's on 10s ans 12s applications where governing is quite abit more important than 3s and 4s trex 450 applications...so I think I know what I'm doing..

It's apples and oranges...you prefer auto I prefer fixed...let's just agree to disagree

anthony, when you say set the low point on the ATV, and go beyond it, do you mean go negative or go a few more points positive? also, when you say set normal curve 0 degrees, then flat for the rest, did you mean like 60 or 70%straight across after 0?
