Hey guys,
I have a Losi BK2 and have a Novack 5800ss coming, but I want to try another system to compare and have one for a back up.

I don't know enough about electrics to pick out the right sytem.
I drove nitro a ton, (don't hold that against me) :-)
so I'm no beginner.

I'm looking for something in the top of the line. What would you suggest if money wasn't a factor? (with-in reason) I know the
Lehner's & Schultz stuff is more, but thats okay, I want something
thats better than the Novack, if thats possible.
Needs to be reliable.

And where to purchase?

I'm using 6 cell 3300 Nimh packs right now, but want the new system to handle the LI-Poly's.

Are track is pretty tight and technical, so top-end is not a factor.
Medium to good traction, lots of doubles.

Really appreciate your help guys, I know some of you guys really know this stuff inside out & backwards (no not backwards!) :-)

My suggestion would be:

Shulze 12.97 ESC (has BEC for simplicity) and either a Lehner 4200 or 5300 for your motor. If you wanted you could also go with a hacker 8 or 10 turn motor with that ESC as well.

The 4200 or the Hacker 8t should be about the same speed as the Novak. The 5300 or the 8t should be faster than the Novak.

If you want to save a little money go with the Shulze 18.61k ESC. It's about $100.00 cheaper than the 12.97 but does not come with BEC which means you will either have to run a seperate battery pack, pick up a seperate BEC (can be found on Ebay for around $20.00 and is a little bulky) or do a direct wire to your receiver. With the direct wire you won't be able to run more than 6 cells though.

Castle Creations is supposed to be coming out with a new sensorless ESC and motor built for cars in the near future. The price is supposed to be competitive with the Novak but would be compatable with Hacker, Lehner and Shulze stuff.

Thanks End Overend ( thats a good name) :-) , thats what I was looking for, appreciate the indepth post.

Is that a big jump in quality going with the Lehner & Schultz products compared to the Novak?


Thanks agian!

I wouldn't necessarily call it a big jump in quality, but I would call it a big jump in flexibility.

With the Novak you are basically stuck with the motor and ESC that Novak supplies. With a Lehner, Hacker, Schulze, etc. set up parts are more interchangable as you can mix and match ESC and motors.

With the Novak you are limited to 7 cells, with the others you can many times run 8, 10, 12+ cells assuming you can fit them on the car. I believe the Lehner motors have a life time warranty. The big problem is if you do have a warranty problem, it could take a while to get it fixed as they are German companies.

Since you are looking at Li-Poly cells in the future jumping to an 11.1 volt battery would be easy with a Lehner/Schulze set up.

Thanks for your input, that gives me a better understanding, and now can figure where & how to spend my money.

Use the Kontronik JAZZ series esc (the most programmable and verstaile one out there !!)
watch: www.kontronik.com for infos (maybe you have to look in the german pages, the JAZZ is VERY new !!

and then a TWist motor for it, maybe you might find one here:

www.icare-rc.com/motor-controls.htm

pic of the twist:
(as they´re only on the german pages and around 150Euro here in Hamburg (another + 170 with a 55-6-18JAZZ)

My $.02... (although I have only a Novak5800 and a Hacker C50 Emaxx)

The more I look at the Kontronick stuff the more it looks good... Jazz 55 or better esc and a Twist... whichever wind you want.

I have never heard anyone complain about the Basic motors.. they must be very impressive, and the C40s are proven as well.

If you want to use Lipos, that may have some impact on what motor you should pick. You will have the option of using a higher voltage battery, so you can go with a lower rpm (k/v) motor, and use the extra volts to achieve a high rpm with lower amp draw. If that makes sense...

The Novak5800, Twist5500, Basic5300... are all high-rpm per volt motors so they are well suited to a 6 cell pack or 2 cell lipo.

But if you use 3 or 4 cell lipo (11-15 volt) you want a lower-rpm motor to match, and you still get a high rpm but at a much lower amp draw.

Ex: Twist5500 and 7.2V battery= 39600rpm
Twist3700 and 11.1 battery= 41070rpm (and lower amp)

The cool thing though, is you can get a nice ESC and then get two different motors, one for 6 cell packs and one for 3-4 cell lipos :)

just wondering why the 40-6-18 jazz controller wasn't recommended, i too am looking to put this in a buggy or possibly a t4 and then in winter run in a tc3 on carpet, is it the higher amp capabilities? :confused:

maybe this esc will be hard on the limit with some heavy motors, but normally if everything is geared and dialed in right, there shouldnot be a problem, but in my case the 55-6-18 is only around 15-20 Euro more than the 40, but having then a limit of up to 65 A comp. to the 55A from the 40-6-18, that is a little extra that might become handy when using it in the offroad 2wd, but for carpet or sedan or 10th or 12th it should be MORE than enough !!
(it is protected in various ways, so a malfunction or overheating may not lead to damage, it is just a sign, that there is some work to do in the drivetrain !!)

Yep, it's a case of better safe than sorry. For a little more $$ you get a higher amp esc, which should run cooler. ...and not go up in smoke.

The Jazz 40 probably is fine, but since the setup isn't extensively tested in T4, etc... I would go with the 55 too...

where can you get jazz controllers?

Mr. Constructor

Maybe you could get JAZZ Controlers in various airplane seller shops, they ´re very often used by them, because they already do have a Li poly cut off safety feature, that NO other manufacturer has !!!
Try to search for these, last way is the direct sell (send me a mail, i will try to help you, finding a dealer that sells internationally, or i will do it myself !!!)

I agree with this and I do not know anything about the 12.97, but I am running the 18.61K with the UBEC added. I would buy both lehner 4200 and 5300 for the type of track or conditions you encounter.

Now the Li-Pos, that's my department, the 11.1 volt TP8000-3S4P Thunder Power battery is too long to fit in the buggy. Stick with the 7.4 volt TP8000-2S4P battery that should fit right into the tray and will be lighter with 3 times the runtime a nickel pack will give you.

Good Luck!
