Yeah, not worth it at all anymore... Mike doesn't carry them, headquarters in Germany, etc... and when I would buy from Finedesign, oh wait, I just heard, it IS snowing in hell.


I would like to see a direct comparison just for arguments sake... a Neu motor and a Lehner motor of equal mass (both being fin-less of course), equal Kv. and run them in the same truck, all things being equal, yada, yada, yada.

I believe byte lives next to germany, so service and warranty isn't an issue. Also buying a new neu in the US can get pretty expensive b/c we have to pay for shipping, 19% tax & some customs duties. So although a neu would still be cheaper than a lehner, the price difference is also less.

Thank you guys for your replies!

Well, drkdgglr is right, I live next to Germany so warranty wouldn't be a issue. But as you guys said: The only place to buy from is Fine-Design? (I heard the whole shop sucks) Isn't there an other shop maybe? (I prefer in Europe)

EDIT: Well I'm asking this because I'm still not sure what motor I want to put in my LST. ESC will be a Quark 125B (I prefer this one) or a MMM. And I'm not sure if I should get a Plettenberg Bigmaxximum, Lehner 1950/xx or a NEU/Castle 2200kv motor...
Anyone could help? (I'm going to run 5S)

We have 2 guys on our austrian forum running a Lehner 1950 in their truggys. A Lehner 1950 is comparable to a Neu 1515.

One of them managed to crack the first segment of his rotor while his plastic spur lost 2 tooths. He was running an old design Lehner 1950 without fan.

Lehner changed the rotor design to prevent the first segment to crack (it's always the first segment that will crack when excess stress is applied on the shaft).

There is now an aluminium plate in front of the first segment and the magnet segments are covered.

When choosing the fan version of their motors you should cover the air intakes.

A look inside a Lehner 1950 can. Windings are layed out very properly.

The easiest way to buy a lehner is to order it directly from Lehner. They provide a motor hotline but are more specialised on boat application.

An LST is a big and heavy monster truck. You would want at least a Neu 1515 (a 1518 would be even more appropriate) or a Lehner 1950. A lehner 2230 is comparable to a Lehner 1950 (powerwise) and would also be a good fit torquewise (a good choice for Muggys too). As you are replacing a nitro motor revving around 30000-35000rpm max you should choose a motor on 5s which gives you a comparable max RPM for proper gearing an good pinion selection. 5s x 3,7V x 1800kv = 33300rpm. Before choosing motor kv you might want to play with BrianG's speed calculator and have a look at how you will mount your motor and which pinion you will be able to fit.

I currently run two Lehners. I have a 1940/7 in my G2R (which started out on 4S, and went up to 5S, and now it goes back and forth between 5S and 6S) and a 1930/7 in my CRT.5 that usually sits on 3S but has seen 4S before.

Both are fantastic motors and I have nothing but good things to say about them. They run very very cool and have plenty of power. They are of excellent quality that is very comparable to (some have argued better than) a Neu. To be fair, there are also some who claim Neu motors are better.

In any case, the easiest way to imagine them is that both are great quality except the Neus are 4 pole and the Lehners are 2 pole.

The Neus generally have more torque, but the Lehner love to rev because of their 2 pole design.

I personally love high rev and top end power, so the Lehner fits me best. My G2R pulls very hard from a stop and keeps pumping to over 45mph with little sense of slowing.

They are great motors and don't hesitate on getting one.

However, I will agree that in the current situtation, they are far too expensive to purchase form Europe and the lack of support makes it worse. For this reason, I would just recommend a Neu if you plan to buy a motor.

Since you live in Europe, I'd go with a European motor. Buying a Neu would mean you'd have to pay insane shipping and taxes and then have to ship to the U.S. for any service that it may need (accidents can and often do happen). If you want a 2 pole get a Lehner, if you want more poles get a Plettenberg.

Medusa 3680: Cover up the holes in the front/backplate and fix the backplate with screws to the can. Best performance/Quality to price ratio.

since price doesn't seem to be an object buy the big maxximum.

people will argue over and over and back and forth over which motor is best and why, and they all have there points.

But there is no one that will argue that the big maxximum is the sexiest of motors, second only to its big brother, the bolido

Interesting conversation..

Just wondering how a Hacker C50 XL would compare in this bunch as well.. Any comments?

Lehner are very good motors. I have the lehner 4200 in my tc3. It trully seems to run better with more cells than with less. I never knew that little motor was so powerful until I recently put a 3s lipo on it. Sick speed and acceleration!
I also am witness that the Bigmaxximum is still the king (or maybe the prince) of the Big Powerful 18cell/6s Brushless motors. I have one, and I wouldn't trade it for nothing!

I believe Linc has some/lots of experience with the Hackers, but they dont seem to be on quite the same level as the others discussed so far? Alright if you are making a pink themed truck though... :eyes:

Well, with 419gr (14.78oz), 74,8mm (2,94 inches) and 2 poles i would say it plays in the same power league as a Neu 1515 or Lehner 1950. I know of one guy using this motor in his truggy. Watch this video from minute 7 on and you will see a truggy powered by a Hacker C50 XL9. Power to spare and he never reported temp issues running on 5s 5000mAh kokam lipos.

I have only used the basic series of Lehner. The 4200, 5300 and xl3100. All had power to spare at the topend. I also use the C50L hackers and like them alot. Rev happy monsters and mine sees 60K rpms on a frequent basis. I also use the Tekno neus, but they don't rev up as quick as the Lehner and Hackers. They do however have torque to spare.

Why is everyone mentioning "top end power", or more "torque".... have you guys forgotten that all of these motors have the same power curve over it's entire rpm range (whatever that may be).

The only thing that matters is watts with these motors... yes, each one might 'feel' a little different(it's all controller firmware), or sound different, but it all comes back to how efficient the design is... which indirectly affects the 'illusion' of how much torque it has, because you have to size each manufacturers motors a little differently because of heat constraints(because of efficiency)... get what I'm saying.

I could be wrong though.

If you live near Germany, just order the Lehner direct from them. For LST I would go 22 series.

The Pletts are very sexy motors but they have terrible warranty coverage, They blamed 2 different controllers for killing my Big Maxx twice. Had to pay for repairs (and shipping from US). Big maxx may survive on 5s whereas I was running 6s, but plett said they run on 6s all the time.

On the other hand I sent a Lehner in for warranty, and although it took a long time, they replaced it no questions asked.
