The term comparable usually refers to items that are not identical...

Cause if they are identical they are not comparable, thay are identical.

So two items made by two seperate companies that are similar can be compared, so they are comparable.

So hacker c50 motors and lehners have comparable performance, but the c50 is larger and heavier due to can design. Their internal design is similar and I am sure the material usage is similar too.

I own both. Neu and Lehner. I think the quality of either one could be called: THE BEST. They each have their own benefits performance wise. If we knew what the "app" was it would make this a lot easier. In a nutshell: if it's light/speedy- Lehner. If it's heavy/torquey- Neu.

Which do you prefer?

[What's_nitro?]

For what?

[BL_RV0]

Say, um a lightweight truggy.

[What's_nitro?]

Lehner < (9 pounds) < Neu

[BL_RV0]

What makes the lehners so much lighter than neus?

9lb truggy

Stick with a neu for those truggy size wheels and tires. You need torque to make the heavier wheels/tires react quickly. If you plan to make it super light, a 1512 or medusa 60mm on 6s should do the trick. Something like 3000mah 25-30c cells for power.

Dont know how you plan to get the truck under 9lbs.... Everywhere I have looked has the kit weighed as 9.5lbs without electronics.

No heatsink and less material due to the slotless stator?

[What's_nitro?]

Mainly the slotless design. That iron is heavy. But the Neus have a larger can as well, then if you get the finned can it's even more weight.

[BL_RV0]

I wish neu would make a 1412....

[What's_nitro?]

I wish Neu would allow us to order custom motors via a "click-and-drag" interface.

Even at 9lbs I would not run a 1930. I ran one in my buggy at 7.6lbs, worked great if geared less than 40mph, anything more and it would start to get hot. I now run a 1940, and don't have to worry about gearing (just getting the batteries too hot,lol).

The Lehner 1930 is a small powerful motor and a good choice for a very light wheight buggy with conservative gearing. On our austrian forum a user tried his XT8 truggy with his Lehner 1930 which he primarely used to power his Mugen MBX5R. On loose surfaces he never faced temperature issues and had plenty of power even in a truggy: see video and picture of Lehner 1930 mounted.

On high grip surfaces and more throttle use the Lehner 1930 run hot: see eagletree graph 1, graph 2 (temp b represents motor temperature in degrees Celsius)

No wonder when you think about its very small mass. I personaly used a Neu1512 powering my buggy and it is was a perfect fit. It also powered my truggy for quite some time but did run hotter than a Neu 1515.

One thing you have to be very careful about when using Lehners optional fan cooled motors is to protect the motor from dust, stones which could be sucked into the motor. There is only a very small gap between rotor and windings. Some pictures of a Lehner 1950 prepared for offroad use by one of our german forum user (PlanBFidelity): shielding pic 1, pic 2
