low end motors vs high end motors

i have been trying to find the difference between the low end motors like the BK Wanderer/Feigao vs the high end motors like the neu and lehner motors.

i currently run a 9xl and its fast and runs great. and i only pad like 70$ for it. but i see a lot of people on this forum running the high end motors like neu that can cost up to 300$ for it.

sorry if this might be a stupid question or if its been covered before. if it has then can some one link me to the thread cause i cant find a thread about this.

thanks!

if you're happy with low end motors... stick with it.. I love the low end motors.. but I love the efficiency and power of the high end motor as well...

The big difference is their overall quality, the magnets are segmented, which makes them more efficient/suitable on partial load.

A cheap motor does the job, that's for sure. Once you find its sweet spot it can run rather effcient as well

what you mean by sweet spot? like a good amount of cooling and the right battery voltage.

what about lifespan? will a feigao last as long as a neu?

gearing too

lifespan; i mentioned quality. It's most likely the bearings are of a better quality, but since they are fair easy to replace..

well maybe i should run mine and then temp it. i just now noticed i never temped it. i just let it cool down when my friends with nitro let there cars cool down in between tanks.

Lifespan.. My bearings on the 7XL went a bit after 2 years... but all in all.. it's a great motor... I really like the 12XL on 6-8 Cells... seems to work for me.. And you could get quality boca bearings for them... A fan/heatsink always helps.. I've had my 7XL for over 4 years now.. still kickin'...

would the neu, lehner, or pletenberg motors work on a mamba max.

I'm very interested in this question too...I've been running Low end motors and I also am considering the switch. Nearest I can tell you get two things, lower temps and better efficiency. My question is how much for both of these...mainly how much more run time. Do they give 5% more run time? 10%? 20%?

About the only thing I'm not happy about with my low end motors is that with 4900Mah batteries I can only make 15 mins if I really drive slow. If I get on it I often times will only see about 13 mins which is often times just a little too low.

After using both XL motors and a Neu, I definitely like the Neu better. It stays cooler even when worked hard, doesn't suffer from the end bell popping off, can rev higher without heating up, and I believe they are made in the USA (which should speed any warranty work if needed).

Motor heat is wasted power not getting to the ground. So, any decrease in temps will mean more runtime. How much runtime is really hard to say. Depends on how you drive since the high end motors are more efficient over a larger rpm range.

But, is the price worth 2-3x? I say yes, but that depends on what your disposable income level is, and what you want for a system (something that works well, or something that simply blows others away).

Well said... sometimes it 7-8 times the price....

I used to run a 7XL but switched to Lehner 1940 after mine broke. The magnets cracked in the feiago on both mine and my brothers 7XL.

So far the lehner works great! I felt like I had no choice but to go high end.

Can anyone try to estimate the gain in efficiency? Surely someone has a setup where the batteries stayed the same and they just dropped in a new motor - how much run-time did you gain? I'd be interested in on the track numbers if I had a choice...
