Lehner 22 series
 

I was looking at a new lehner 22 series. Not sure but the motor seems bigger in diameter. Looks to have 4mm mounting screws as well. If so Do I have to make a motor mount? Any comments on people that have this motor. Is it worth the money. Don't mind spending if it is worth the money. Thanks all

These motors are LARGE! I think the 1940 or 1950 series is all you would ever need. I run a 1940/8 on 22.2 volts and it doesn't even work up a sweat. the 1950 would be even more effortless. These motors are worth the money IMHO. They are smooth, powerful and run cool compared to non-segmented magnet motors. A customer recently picked up a 2280 motor for a boat. The motor is like a soda can in size! You would need a beefy motor mount to secure it for sure. The 19 series bolt right up, though they are a bit heavy for the g-maxx motor mount (works fine, but the 37 foot jump at my local track was too much for the big motor on this mount!

Only 37 feet. Would I need a special mount then for the 22 series? I know it may be a little extreme. Look at my signature. I drive a truck with 600 hp on the road. :D What can I say? I got it bad. RCing or not.
Is there a way to mount like a bracket or mount to back of the motor as well?

A bracket to support the rear of the motor is exactly what I have in mind.

What about the front? Is the Mounting stuff Like i think. Mount bolts 4mm and spread a little farther apart? Never saw but pics.

I didn't really look that closely at the mounting configuration of the 22 series. Pretty sure it needs a custom mount though.

It looked like it. Just want to make sure. Thanks alot mike. If you would mike Pm me a price on the 2240 and 2250 series. Thanks

I'm pretty sure that Promod ran a 22 series on his maxx and said it was fast and made plenty of power.

Because a pic tells more than a thousand words..

I am dubbing with some ideas too..

I wanted a 2240-2250, but i got a 2nd 9920, and i don't know if i want to go above 20 cells.. The 8XL or the 9XL sounds tempting too, but i want to get a setup that could easely push my truck above the 60mph.. Perhaps a 36120/36150 and a 2250 is an option.. (or even a 2280, i like the motor being huge..)

This is my threory. If you have more power than you need. You don't have to pull the trigger that far. Adjust your epa on controller. If you don't have the power. You are SOL. (sh## Out of luck)
@ serum If you get yours before i do let me know how it does. If I get mine first I let you know. I don't think I going with the 2280. I stick with 2250 or 40 Just not sure what turns and stuff I going to get. Need to get a controller to. OH well! Have to work a little harder make some extra money.

On the other hand, i am curious what your 9XL does on 20 cells!! ( i was thinking about planting that in my savage w/centerdiff)

It should be awesome fast. The question is, how far do you want to go? i want a truck that can bash, race and be scary fast. Perhaps my new challenge is 20 cells, lightweight and with a centerdiff. handling is the needed for a fast truck.

something like a 65 mph truck is nice, but when are you using it's power when you drive offroad.. A nice racer on 20 cells, perhaps that suits my needs allready..

What does the pitch diameter mean? Is that the space between the mount screws.

Yeah, that's it..

Heart/heart

Need another motorplate.. ;)

To each his own, and I don't want to start nothing, but 60+mph in an off-road RC is just too much. In My Humble Opinion! First of all, where do you want to drive it? On a soccer field?
40-45mph is plenty. Period! Even on a BIG track.
Going for records in the name of science is all good for me, but I want my RC's to be driveable. AND, lots of cells, 18 and more, give you such an extra weight, makes a truck hard to handle, and impacts really hurt.
But, oh well, I'm dreaming of a sick over-powered RC myself. But just simpy can't afford it. One day, who knows?!
Have fun, and enjoy the hobby. (if only those Lehners would be a wee bit cheaper:rolleyes: )

Others have indicated that larger motors (cans) take longer to spin up.

Anybody know the theory behind this? And more importantly, if its accurate?

Finally, is there a formula to indicate the rate at which a motor will reach its maximum RPM given consistent factors (resistance, weight, etc.)?

C.H.U.D. - The larger a motor's rotor is, the more time it will take for it to spool up due to a heavier weight. This is very accurate, as a 400 size motor's rotor will spool up to top RPM MUCH faster than a Lehner 2280's could.

Dafni - I agree, although having the extra available speed is nice sometimes to be able to show off to friends :).

As soon as the mow down the corn I have 38 acres to run. A little bigger than soccer field. I like to make my own track up. I have to get back to that another day though.

You really should not have to get an enormous motor like 2280, but I would rather get the 2240/15 and feed it with enough lipos to take me to the 60+ world. This way you will save weight and money and ofcourse you would have enough room for other things.

Well, the truth is;

They will spin up slower, but the have got a HUGE factor of more torque. You really don't want a motor that size to spin up really fast. But here is my theory;

Due to the mass, they may spin up slower, but that very same mass, makes them also much stronger. It is that particular mass that makes them that strong and heavy.

You don't want a motor to spin up in less than 1 seccond from 0 to 30K (those large motor also need less rpm's, because they have got the torque needed for a larger gearing.) Also; because of this larger gearing, the acceleration with a less fast reving motor can be faster than a fast reving smaller motor, which needs the rpm's to make speed.

All and all, i vote for the large motor vs the small motor, but i simple am not a racer.

@ dafni; i like a truck being fast. 45 mph doesn't push my buttons. you don't need to drive it that fast, it's the huge acceleration and power that makes it lovely to drive. I personally don't get a kick from driving on 14 cells. 16 is net enough for me. It's just the difference of everyone enjoying the hobby his own way.. It's the never ending discussion between die hard bashers and shelve queen builders.. between the 14 vs 20 cells and up setups..

My maxx will be powered with 16 cells, i think it's too pretty to be wasted and trashed with a big ass setup, that's the reason i am planning on buying an easy to maintain/strong stock savage and do a 20 cell rebuild on.. It will be rather light, the extra weight the cells add will be overruled with the power the extra cells give. Like i said, i don't drive tracks.. I am that idiot that needs a HUGE field to enjoy his hobby... driving it on a narrow road also adds a little rush of adrenaline..

Here we go, Serum.

Well, me too.
Okay, I see. All power to you, then.
Hey hey, I'm no shelf queen builder. I drive RCs whenever I find the time and the weather allows. Sometimes even when it doesen't.
Me, I like sharp turns and smooth runs better than insane straights. But this could also be because I don't have the $$ for a big Lehner and fat fat Lipos. I always say to myself I can still get something serious when I grow up :D I don't even have a real radio... but I only just started.

Like you said, to each his own, mate.

peace

A heavy truck needs another handling from the men behind the stick.. ;)

I am that shelve queen builder i'm affraid sometimes..

I'll let you drive with a 20 cell monster when we meet, in Swiss or in Holland..

Perhaps you'll like it.. ;)

You'll get me addicted, no doubt about it :D

But we'll have to find a track somewhere .... I'm not bad behind the stick, Rene.

And don't get me wrong, I never said I didn't like it, okay!?

No, i know.., you're the last who would say anything bad about anyone or some ones vision Daniel!

I like a car that makes me grin when i punch the throttle... it might be electric, but you sure can hear the power of the truck taking off..

Sure. I'm still getting used to the 7XL, makes me grin, too. This thing is already very fast for me.

At some spots I drive, even the Titans are fun. btw. And I'm no crawler, either.

We all love the big power. I strap 6s Lipo in when I need the speed rush, but I am admittedly mostly a racer. The 1940 is almost a large as the 7xl, while the 1950 is slightly larger. These are not small motor by any means, and they easily power the trucks. The 22 series is the extreme. It is large and heavy, requiring more work to make it work. I am quite sure these are a heck of a motor, but I would race my 1940 against the larger motors in these vehicles any day. The motor is plenty and I doubt the larger 22 series would provide any performance advantage(actually, a disadvantage due to the weight). They sure do look cool though, and can surely last a lifetime, as they will be on vacation in the e-maxx and savage trucks!
To each their own, though. I know Barry(Promod) strapped one of these motors in his center diffed e-maxx and loved it.

Well Mike, like i said, i don't race.. it's jus the acceleration and the topspeed that does it for me. the 1950 can be powered with lots of cells too... it's a nice 'in the middle' solution....

Seems me and you serum think very simaliar. I like the big power. I don't race. I like wide open space. I run around sometime slower speed than others. I starting to wonder if 18 cells is enough for me.
Either way you go. If you enjoy what you do. Don't stop. I like the extreme. I can dial it out better than in. If i can run a motor at 30% epa and have a blast so be it. I can't get more than 100% out of the motor though. Just my way of thinking.

I have question. I found this while reading up on the 22 series.

All motors with the exception of the Basic series have the ability to change winding configurations. It's like having 2 motors in one!

Is that like the back of the 30series motor i posted a pic of. Is the 22 series like that. Can some explain what it does if you wire differently?

Yeah, you can chage the routing of the wires, you can make it a more winding motor.. (stern), star configuration.. only the normal types have got this feature, the HighAmp things don't support it.. (more soldering points = higher lost)

Coolhand, you know what would be awesome? A big fat oval on your corn field! Only 4 corners to worry about, but lotsa room for your 60 mph beast!

If I bank the corners. I would never have to slow down. Look like a daytona speed way for rc made of dirt. I Like to have a few jumps and such. I thought about renting a small loader and going to work. I have to lay the track out first.
What kind of motor did promod use?

No, no corners Daniel.. It simple starts to look like a circuit again, we are paranoid for circuits.. (our therapist is aware of this..)

Promod used a 2240/12 if i recall correctly..

Dang, everyone keeps talking about how 16 cells isn't enough for them, 12 is just crazy enough in my Ofna 9.5 with a Lehner 2800xl. Keep in mind, I usually run on the little street next to my house, it can't be any more than 30' wide and 100yds long.....the 9.5 can be a handful real quick if you're not a good driver. :D

I run at my moms some time. In the front yard I have about 15 feet wide about 100 yards long as well. Trees one side 8 foot drop the other side.
What turn do you all think I should get. I was thinking 10.

I once rammed a large pole on full speed.. It was on a very narrow bicycle path, with trees next to it.. I was doing fine for about 4 times, the last time, my ESC batterie was running empty and the steering servo was acting weird..

(what an excuse, it was just poor driving.. no, really, it was the receiver pack...)

Another thing I'm starting to regret... I should've ordered the 2250 instead of the 1950.... Hey Mike, is it too late to change the Motors for a 2250 instead?... :)

wow...a 2250-7 turn on 10S lips...that would be uber fast.... or a 2250-9 turn on 12S, awesome setup...:)

if the 22 series areso powerful.. I wonder how much power the 3080's would be... hahha 1.6KG..

now that's a real beast...

If you had a bec serum You may not have crashed. :)
The 30 80 would be a beast for sure. Have to upgrade shocks for motor weight. :D
