kontronik jazz 10-32-55/ twist-42 combo
 

The people at kontronik said that the jazz 10-32-55 cant be used for rc car application, but the instruction manual that came with the ESC said that its possible to programm this controller for rc car racing so whom to believe? and can I use six cells with it or is it only built for the usage of 10-32 cells? I have this controller for along time and I thought that I can use it with the new TB EVO 4:cool:

Well I have heard that the jazz esc work with cars, but I also heard that they have lots of cogging problems.

I think it was lipomaxx, maybe check with him.

Well, I guess it wont help. The 55-10-32 ESC is really not suited for rc car applications, I have already tried it in the B4 with the LEHNER 1920/8 turn motor and the motor's performance is not as good as it is when I connected it to the BK 9918 ESC, the acceleration was really poor and the ESC thermals alot, just after two minutes of running on 10 cells and even with a cooling fan the thing still thermal and NOT TO MENTION THE COGGING, THE COGGING IS REEEEAAAALY BAAD. So I think a basic 5300 + 9918 combo is the best combination. I also thought of the twist-55+ schulze u-force 75, but I dont know what people think of this controller. Please provide me with some help.

I would not buy the U-force, since the mamba maxx is coming out. Even if the Uforce is as good as the mamba, you still have to figure in CC has great customor servce along with it being in the USA.

But its going to take a while before it comes out. right? I'm a bit hasty.

I belive mike quoted 6-8 weeks on the castle creations mamba maxx.... check this: http://www.rc-monster.com/forum/show...=&threadid=627

What is the AMP rate of the MAMBA MAXX by the way?

there are no details on specific amp ratings. But 2400watts at 19.2v (16cells) gives 125amps peak current.......

120 contius.

400 SURGE!!!!

Here is a video: http://www.rcuniverse.com/magazine/a...article_id=525

Scroll till you find CC.

This is might be the amp rate for the brushed motors?

BTW, what is the difference between the basic 5300 and the kontronik twist-55? I bet their almost the same.

I think the twist is made better, and is alittle smaller than the basic.

The twist and basic 5300 will perform very closely. the Lehner will have a little more torque, bu the twist will accelerate a little quicker in a small car. The twist has the nice heat sink built into the can, too. I doubt the twist is made "better". Just a little different.

Okay, then both the L.B. 5300 and the K.T-55 are almost the same. Now I would like to know which spped controller would be the right choice to go with them (in a touring car that is). There's the Schulze U-force 75 and there is the Kontronik Jazz-80-6-18 ESC and the Warrior 9918 ESC. The Schulze looks great, but I dont know about the K. jazz 80 some people said it coggs alot, but I dont like the 9918 in terms of size and the BEC issue. The Mamba Maxx is going to take some time befor it comes out so I wonder which of these ESC's would be my best choice for the TAMIYA TB EVO 4 MS.

My vote would be the MGM then. Or if you dont mind spending the extra $$$ then the uforce.

I now want to know if my Jazz 55-10-32 esc is capable of handeling circumstances of rc cars applications and specially off road racing. When I used it with the LEHNER 1920/8 turn motor it really did n't work very well, but I guess its because the motor consumes higher rates of amps than what the esc provides specially when it comes to sudden acceleration( dragging) and so on and I think it wont do the same thing if I connect it to a small motor like the TWIST-42 which only needs 40 amps CONT. and 60 AMPS SURGE, but then again only people of experience can give some hlpful answers.

Any controller that is not specifically designed for cars will not be ideal for car applications. The software simply is different. It has been said, also, that the the kontronic controllers only work well with the kontronic motors. For car/truck applications, you should get a controller designed for this type of use.

I konw that Miky and that is why I'm puzzled, the manual of the Jazz 55-10-32 said that I can programme it to car racing application and they gave me the steps to make that program active and it really worked very well, but not with the 1920/8t on 10 cells. That is why I'm thinking that the 1920 requires high current, higher than that of the Jazz 55-10-32 ESC. The controller produces 55 amps cont. and 70 amps surge, but it thermals. The gear ratio might be playing a big role here. I'm using 52 spur and 15 pinion in a B4 buggy.

Does the controller work well before it thermals? As I said, the kontronic controllers seem to work best with Kontronic motors. Gearing down would help with the thermals, as would a fan on the controller. The twist motor(4200) or lehner 4200 basic will both draw less amperage than the 1920/8.

NOW YOOOOU finally got to the point, I've used a fan and the controller needs a bec or receiver pack to work and I put a pack and believe me the thing is silky smooth, but it starts to thermal once you use sudden acceleration more than 3-4 times, after that I started to think that the 1920/8 is too big for the 55-10-32 to handle, but maybe the twist-42 will work much better and yes as you said its smaller and it surely drains less amperage than the 1920. The gearing hasn't changed since then though.

What batteries are you using? If it starts to act up after 3 or 4 hard launches, it could also be voltage drop (I am not too familiar with the kontronic stuff, but most controllers cut out when the voltage drops below a % of the starting voltage), although 10 cells shouldn't drop voltage that quickly. Drop a couple teeth on the pinion and see what happens. Ultimately, you would probably be better off with a better matched set, though(smaller motor or bigger controller).

I dont think the problem is with the battery. They are produced by Team TRINITY and they're amongst the best of the GP'S in the market. The controller as I said thermals after 3-4 times of taking off, then by the next drag the motor barely moves, but just give the controller 5-10 seconds and then it accelerate as good as before, you know what I'm thinking? the controller gets very hot and after it thermals the air that is blown into it by the fan cool it down a bit and then it functions properly once again. So I think the problem really stands behind the amount of current the controller provides, but what is more important is to approve my hypothesis and bring the TWIST-42, otherwise I might need to buy a BK 9918 or wait till the MAMBA MAX comes out, but first the problem must be identified. Yup that's right.

It certainly sounds like it is thermalling. I think you have it pegged. A smaller motor will likely solve or at least minimize the problem.

Yes I too guess so. According to Kontronik the Twist-42 drains 40 amps continuous and 60 amps surge. So this motor is ideal with the Jazz 55-10-32 controller. I have the fun-42 which is identically the same as the twist-42 except that the mount holes in the twist is designed to fit in rc cars and unlike the fun-42 which has a very small diametre and I could not bolt it into the motor plate but only through one mounting hole, plus the twist is designed in the shape of a heat sink and it looks like a real motor.

I think there is also a mounting plate that will allow the fun motor to bolt to a normal 540 mount. How far apart are the mounting holes placed on the fun motor?

I think the motor's diametre is 25-28 mm and the mounting holes are 19 mm while the regular 540 motor's mounting holes are 25 mm. It is obvious that the difference between the two is really big. BTW, where can I find this mounting plate for the fun-42?

BK has them. I ordered one to try out just for this purpose. My money says it will work perfectly for this application. I have the adapter in my hands-it looks like it will fit a few different motor and allow them to mount to a normal 540 mounting space.

How much will it cost if I want to get it? this way I will not need to buy a twist-42 and I'll be just happy with the FUN-42. Oh, and one other thing: the thickness of the plate. How thick is it?

I think it costs around $10. It is about 3mm thick and will work for motors with mounting holes from 16mm-25mm .

Now I can try the fun-42 without the mounting plate as long as I can keep the B4 out of crashing since the motor will surely move a bit, because it is mounted thruogh one screw and that will strip the spur gear as usual.

I wouldn't use it with one screw. The motor will surely move, even without a crash.

Then the plate is crucial. Do you think you can stock some of them?

That is my plan! I may have a few within a week or so(placing order tomorrow).

Am I going to reach 60mph on 10 cells(doubt I can), I think 12 cells will do the job. But the motor will surely pull the buggy on it's back.

On 10 cells, you could probably reach 60mph in a small vehicle. Another user on these forums got his traxas bandit over 60 with 7 or 8 cells.

Yes, but that was with the 5300 which has both torque and speed. I think it would be a bit an overestimation of the fun-42 to compare it with the basic 5300 dont you think so Mike?

The fun won't have the torque like the 5300, but on 10 cells, it will put out some power.

Ok Monster, I have not yet made an order for my touring car setup and I thought that it would be good to discuss it with you buddy, so I thought I have told you that I'm planning to get the Twist-55 with the Schulze U-Force 75 esc for my TB-EVO 4 MS and I found a good site that sells them( not finedesignrc though). It's name is ICARE-RC.COM. They truly have a very large selection of motors from Plettenberg to Hacker with the exception of Lehner. I dont know what you think of the setup, but I do like to have your recommendation on the most ideal setup for my touring car. I want something to go against the 9-8T brushed motors with ease and I could not think of something better than the Lehner 5300+U-Force 75 or K.Twist-55+U-Force 75, but which will go easier on the car and deliver decent speed at the same time? You've been a great help for all of the members of this cooperative forum M.Mike and your work is most appreciated. Thanks a million pal.

where can i get a ktwist 55?
i can only find the 33 and 37

The u-force and twist 55 will be an excellent setup for your touring car. The Lehner motors, Hacker c40 motors, kontronic motors are all excellent motor choices. Plettenbergs are nice, too. There are many options to choose from. MGM controllers are very nice and very smooth as well, and are a bit less expensive compared to the u-force (120 amp MGM will be more capable than the u-force at a fraction of the price-it won't run brushed motors, though).
