Lehners are in!
 

All the motors are in except the 1950's.

Buy away! :)

Umm, not really. The only 1940 in stock is the 1940/10 Hi-Amp.

Oops, should've check before i posted. Hope they're in soon though.

I'm 50/50 on hoping they're in soon. If I still have $ in my Paypal account when they come in, I'm not sure if I'll be able to resist buying one.

Yeah, I jumped on adding a 1940/9 to my cart, but got the dreaded notice.

Dang.... You got me all excited there for a minute....:019:

You prepared to deal with 4mm shafts?

The 1940s can be ordered with 5mm shafts BTW.Flighttechdistribution in the uk have 'em,so it must be possible to order them from lehner.

on second thought,it's maybe a mistake by them,they have 4mm and 5mm shaft versions listed but it's the only place i've ever seen them.

Actually, I'm not sure I would go with the 1950 anyway. I ended up getting the 1940/10 hi-amp for my CRT and it's awesome. I'm running a 4s lipo and the MM ESC and it's incredible. When the new ESC's come out and I can go to a 6s it will be sick. The low KV of the 1940/10 is perfect too. I can say that I'm glad I didn't go with the 1950. Just my opinion, hope it helps someone though.

MM, the 4mm shaft is somewhat of a PITA, but I really wanted to try one of the Lehner motors. I've heard really good things about them.

I suppose that their still being out of stock may turn into a blessing in disguise at some point. I'd be getting a neu if I had a controller that would run them reliably.

I don't know why people hate to try out schulze...
I feared them at first( I had the U-Force75 and I have the 149.18), but they turned out to be very reliable and stay cool even after harsh usage.

Probably the " loose connection" thingy has something to do with their performance.

Eversince I've hardwired the controller to the motor, the thing never went hot or made any crazy cogging.

Probably you might want to give them a try.

Damn...

When you said Lehner are in - I almost jumped out of my computer chair to yell in excitement.

But then I saw "EXCEPT 1950's" and my reaction was aww...

I've been desperately awaiting my 1950/6 Hi-Amp...its been like 6 months. On the plus side, Mike says I get dibs on the first Hi-Amp that comes in.

LOL

Can't imagine what anyone would need a 1950/6 Hi-Amp for.

BP- I've got the same motor on my wish list. Money is sitting in the paypal account. I hope it doesnt evaporate before the motors come into stock.

Because their service is worth poop.. Apparently you didn't need their service, otherwise you would not recommend it to anyone.

if your controller didn't die because of you, it's kind of frustrating that schulze has its finger pointing in your direction. 'loose contact' is their argument.. needless to say they have got a serious loose contact in their develop department.

It's not about the stability of a controller, it's about the service the company delivers. Since schulze has got the service of a Chinese restaurant, you are better of buying another controller.

Every brushless controller goes from time to time. No way around it. There is not one controller that is 100 percent bulletproof.

Quite obvious i am frustrated about schulze, but the least i can do is prevent people to buy a non warranty product.

Commuting :005:

I have one of them and love it. (similar KV than the 7XL, BTW)

You are using it on 4S, right?

I will be running it on 4S, yes.

Yeah, correct!
You saw it in my buggy, when I still used 14 cells.

4S is perfect for that motor!

BK is not getting any better than Schultz as well.

Daf,

Have you ever tried it on 5s? I was thinking about this for a hot setup on 5s. I know its oushing it a bit, but I run my 1940/7 on 5s all day with no issues. I was thinking I could do the same with the 1950/6.

Or do you think I would be better off with the 1950/7 on 5s for every day use and throwing in 6s for power/speed runs.

I had 5S on the 1950/6. It works well indeed! But it is quite insane, to be honest.
For 5S I use the 1950/8... still insane, but gives better temps than the /6.
At the moment I am pretty happy with 4S setups.

Yeah, get the /8 for everyday use on 5S and the occasional 6S rush.

Could you give some more details on the performance and setup? I have a MM/4s (sometimes 5S) and a 8Xl. The setup and speed is good (tho crazy on 5S really) but I've been doing different bashing lately w/ alot of partial throttle and things are getting pretty hot.

I'm thinking about a new motor, but MM doesn't like the Neus, and the LMTs cost nearly as much as my Xbox360. :0 Considering a LMT/MM or possibly a Tekin ESC and a Neu (if they work together.) Looking to get a cool setup w/ 40 mph on 4S.
LMK

From my experience, if you want a cool setup, you'll need 5S for 40mph.
I found 4S is good for 30, maybe 35mph, for long runs.

Exactly why I sold my last 9920 as soon as I got it back from BK, and why I won't EVER buy another BK. The last wait for me was 6 months, WAY TOO LONG.

I'd have to agree that buying from BK is a real pain in the rump at best. Not only that, but all the BK controllers and motors aren't even that great IMO. The thing that really chaps me though, is the fact that they have a fricken monopoly on Lehner motors. There is no substitute for the high end Lehner motors and I can't do without them. Wish there was another company that could compete.

Well, I'll do my best. Basically I have a CRT truggy with the MM esc, Lehner 1940/10 hi-amp motor, and a Hyperion 4s 4350. I'm running the Kyosho 44t spur and a 13t pinion. I don't know the top speed, but it seems close to 40. We run a smaller track though - not full 8th scale. Anyway, I can run my setup cool for just under 20 minutes before my battery dies. At full race scenario, my motor temp is 120 and the esc is about 130. I would agree about getting a cool running 40+ mph on 5s though. When a good esc comes out, my setup will be insane. I'm tempted to keep it 4s due to how awesome it is right now though.

Hope that helps you.

Lehner is no longer using BK for distribution. I ASSUME that is why Mike was able to get some again.

Really Daf?

My HV4.5 did 40mph on 4S and ran at 110* all day long (did a couple runs that were over an hour and the motor was ALWAYS at 110 monitored by telemetry).

I sure hope the 1950/6 gives me more than 40mph...because it alone is more than the entire HV system was. I'm hoping to get close to 50 out of the motor to be honest... (PS - I'll be using flightpowers if that makes a difference)

Is there a sleave or a bushing that can be used with a 5mm pinion so that it will fit the 4mm shaft. Awhile back I bought a pinion from Mike that had that same kind of deal, a sleave that fits into the pinion which made it fit a 5mm shaft.

What is the proper name for those? And where can they be purchased from?

I believe those are called bore reducers.

I am aware there is a 6mm to 5mm one and a 5mm to 3.17mm (1/8in) but I do not believe there is a 5mm to 4mm one...

Yes, you can get a 5mm to 4mm reducer. I have a 5mm to 4mm and a 5mm to 1/8" reducer.

The only place I know of to get them is Mike. They look like a a PITA to make. I'm sure he can't be making any money on them, but he will make them for you if you request it.

I stand corrected :)

The bore reducer I got from Mike looks like it is aluminum. So, make sure your pinion grubs screws are in tight and use lock-tite because if the shaft spins inside the bore reducer, it will wear it and make the pinion wobble. Trust me, I know from experience...

Brian you are right about that. I wouldnt consider the reduceres as a permanent solution. I bought mine when I first got my 1940/7 and didn't know what gearing i was going to need. I used the bore reducer with my 5mm pinions until I figured out what the right gearing was and then I bought the correct pinion gears with the 4mm bore.

Plus in a pinch if you loose your pinion and need to run a regular 5mm pinon to get you through the day, they are nice to have.

I was talking about race conditions. Just what I found. 40 on 4S works, but 5S is better for those speeds. Just what I found.
Of course you can squeeze out almost any speed of those setups for short speed runs.

I use FPs too.

The 1950 will have twice the power of that little Novak, no worries.

I have to admit, after one hour constant running, temps of 110°F sound like a serious miracle... just look at the efficiency: If you take the amount of energy that it takes to move your revo around for one hour, and only use 5% of this as heat loss, you'll still get a hot motor. Not saying you are wrong, but from what I learned in the world of Brushless, if you run for one hour and your motor is cool like that, you're either taking breaks, or you're crawling, or you have very very low ambient temps.

110° after a one hour race? I'd love to see that in person.

Just sharing my experience, no flames please.

DAF

Like I said in the other thread.. this is excellent news and BK Electronics can officially die and burn in hell for what they've put us threw. Lehner needs to just make Mike their official Lehner dealer for North America.

+1

I agree.

Thanks you two. The info was what I was looking for. It looks like that is the real deal w/ the ESCs. I would really like to just go to 6S when a capable controller w/ good CS+support comes along, and have 3S packs to share between my trucks. 50mph is fun, but its really too much for most things, so my hope is to go 5-6S and aim for ~low 40s and be extremely reliable and cool. Any chance a Feigao (~12XL) could do this as a stop gap? Relaistically I'll be upgrading in stages.

Sorry for the hijack.

& +2 on Mike/Lehner
and Boo on BK.
