Lehner Hiamp?
 

Hello guys, thinking of getting a Lehner 1940 or 1950 for my RC8 on 4-6s. Not sure which yet, leaning towards a 1950 for the 5mm shaft (although I noticed on their website they say for "LK" versions only, what does LK stand for?).

Just want to know what the Hi-Amp versions are and just the general difference between standard and Hi-Amp?

And also, what are Neu's like in comparison? Anyone who has experience with both would be appreciated (in a performance POV, price isn't a factor for me).

The LK versions have the cooling fan in the front of the can- not really needed for ground vehicles due to sucking in dust.

The HiAmp versions have a single wind of wire apparently, meaning they draw more current but produce greater power, or some troddle like that- only much use a giant plane or boat with good airflow or water cooling.

In general though, the lehners are 2 pole motors, meaning they spool up faster and are good for high rpm setups, but for ground vehicles over a certain weight range the 4 poles Neus and similar motors ( castleneu, medusa ) are better; these are slightly slower to spool up but produce greater torque/ are better at pushing things like truggies and MTs (less likely to overheat).

Given the prices and relavite performance, I'd say stick with ccneus as they are everybit as good as a true neu motor and alot cheaper; I paid £120 including postage for my new 1518 motor, thnough add on £30 for import fees and taxes.

Price may not be much of an issue, but I see no sense in paying more than double for a motor that isnt much or any better..

I would run the Neu motor as well.
I like the both motors.
I have had great luck with both motors.
I just like like the neu a little more.

For 1/8 and larger the 4 pole motors just seem to be better than the comparable 2 pole motors. I like 2 pole motors for 1/10 scale touring cars, crazy acceleration! Same thing with mini vehicles, the 2 poles have less torque so they do not destroy diffs as fast.

Thanks a lot guys, helpful there, I'll just go with Neus then, means I can get the Slipperential too.

Is the 1515/1.5D/S a good choice for 4s? Tad on the high side with 2700kv but I like to push things. What does the S stand for?

Why doesn't Mike stock the 1519 Neu motors, they are slightly longer cans, similar to Castle Neus or Tekin use am I right? 75mm/3".

And are the 1515s 5mm shaft?

I think you mean 1515 Neu. 1515's have a 5mm shaft

Ooops, yep, that's right.

The S or F used to stand for smooth or Finned.
