lehner 1950/6 on 14 cells?

Would this run hot? Geared 40mph. Does anyone know where to get one? I would really like one.

I think you're good to go on temps with that setup. You may have to take a trip to Germany to buy one though, or get one from FD. Or better yet you could try a Neu, let's say a 1521/1.5D (1860kV).

isnt that to big? How the power of the 1950? How long are the cans? Man I wish I could get this, not the 8xl. Whats FD? And what is the difference from the hi-amp to the normal one? Are the 3.3 MIP CVDs strong enough for this kinda power?

There really isnt much difference between lehners & neus, only that lehners are very hard to find, where as neus are abit more plentiful in the US- but expensive. The cvds should be good to go, just do something to stop the pin from flying out.

On 12/14 cells I would say the 1515 1y or 1515 2.5d would be good, lots of other people report good results (anything in the 2000kv area is good really).

But I want to run a MM. And they dont have the 1950. Man I really wanted a 1950, Will the 1940/7 beat the 8xl or 7xl?

I'd just be worried about the batteries. A 1950 can pull a ton of current.


A 1940/7 would run circles around a Feigao XL motor. A 1940 would probably be better on NiMH, as it wouldn't strain the packs as much.

I have max amps WCE 4200 7 cell packs. Will this be enough power for me? Also on the diffs, what diff the HB Pro or just the HB diffs? Im getting them here so?? 51/20 with buggy diffs What do I cal. the gearing on? Full volts or load volts? 1.0v per cell or 1.4 per cell. Will it also get more runtime? Im planiing to get 4s or 5s packs in the future. 5k to 10k mah idk I read someone got 35mins of runtime on 4k packs. (1940/7) Will the 1940/7 pull to much current from the MM? What hinge pins and diff oil do i need?

You ask too many questions :) The batteries should be treated like 1.0v per cell underload when doing your calculations. 1940 motor will be plenty, and you can can plumb in the different gear ratios / motor turns into the speed calculator to come up with some answers. Just remember that 40,000 rpms is the target motor speed, and 40mph is plenty of speed vehicle wise- adjust gearing/ voltage to match really.

Just saw his thread. The 1950/6 on 14 cells is a nice combo. My 100amp ESC got hot, but was fine. So did the batts, when I still had NiMH cells, now I use it on 4S (with a MM).
On 14 cells it's plenty fast, Serum can attest. Had it in my MBX5 once, with a 9920.

Well it looks like no one has the 1950 so I guess Ill have to get a 1940/7.

Actually there is a big difference between the nue and the lehner, the nue is much fatter and won't fit in most of my trucks and if they did gearing low would be very hard.

I run a 1950/6 in my BL 1/8 buggy. I love it!!!!!!!!!!
Ran it on 14 cells with BK 12020 Super FAst!! But, Heavy!!!
Running a pair A123 6.6v 13.2v Good combo A lot lighter and still quick as can be!! Depend on gearing. I'm running 16/46 or 18/46 Motor and esc are just warm.
The MM not sure if it would handle it. Go with lehner 1940..
hope this helps.

How did you get a 1950? How can I wire up the lehner to the mamba? (4mm connectors) I thought I can plug right into the back of the lehner?

[suicideneil]

How is a question of looking around ALOT until you find someone with them instock (rc boat places is a good bet). Wiring it up is simple enough, you may just have to direct wire it or change the plugs on the motor or esc so they both match in size, no biggie really.
