Why yes i do. I like it. It made me a better driver. :D It just took some reading to figure out what all it does. It is not top of the line. It does what I want it to and then some.

I'm glad we can all come allong so well..

;)

Well,

I have just read this topic and those motors are just sick!

Those 30-series, are not normal to put in your 1/10 truck, even the 22-series are extreme.

I will run my 9L on 14 cells, what a little baby it is then. Well it's light, probably fast (in my eyes) and it has much better control than beasts with 20 cells or more, that's alot of weight!

Well, who needs a set of ultramaxxed gears. I have one brand new in package with grease and idlers and might sell it for the right price.

pm me then...

Me too!

Respecting each other is what it is all about.

It would be a very bad thing when even we here, as likeminded RC fans, would get hard feelings towards each other, just because we exchange opinions.

We're grown men, after all :L: big boys with fast toys

Yes, that's true!

But I have a whole other view toward these motors for like outboard motor on my little tender boat.

Actually, my post was directed at Serum. Nevermind

Who's talking about 'not normal' what would you do if you don't get a kick from driving a 14 or 16 or 18 cell monster? Quite the hobby and stop having fun? 20 cells and up.. Yeah, it's some weight.. But who cares.. the motor loves the extra juice.. it's all about the speed the monster passes by..

Controll is all about the person who is behind the trigger.. And i am Stevie Wonder.. (makes a heck of a nice movie of the monster in action..)

10000 watts?

that's power to move a yacht of 5 tons, since I follow this projects.


So not normal in the way that it's extreme, do what you want to do in this hobby. Make it as crazy as you want or as you like!

Well, everyone has the freedom to do whatever they want as long as they dont hurt themselves nor the people around them.

Everyone, I'm starting to go nuts again and this time.....MWAHAHAHAH..:devil bolting a 2230/7 in my pooooor T4 and use 4:1 gear ratio with 16 cells. I....will....make it..daance.

Its all thanks to you and to your great thread about the 22 series, though it is for the big trucks, but not the poor things. HAHAHA:cool: , who cares.

Please get a video of that captain. I would like to see.

Hold your horses, Cool buddy, I'm only thinking about it. I still need to find a way to bolt it in the truck. The motor is waaaay bigger than anything I've seen. And I did not get it, yet.

You seriously need to see our group therapist captain..

My dad always said, "When you think you have too much power, add a little more and it will be just right"

Well, your father must agree that a dual 2280 setup on 72 cells is just a bit too much for an emaxx..

Too much, I doubt it would be controllable, I wouldn't have fun using something that stupid powerful.

I think serum meant this in an ironic way :D otherwise I would have to have a word with our therapist.

I once saw a boat with dual 22 Lehners and 64 cells. It was made by the BK guys, and they said it's the first run. Must have been, both shafts ripped at the first punch of the trigger. :eek:
The guy just floored it, I think. Man, this huge baby did a nice kick start! And then they had to pull it in with a rowboat. :p

Out of intrest, what is the cell range the 22 Series Lehners run at?

Okay captain I holdin them back. :) I thought you was building. The sounds of that project got me pumped up.
@nick It depends on which lehner you get and turn. Some of them motor should take 40 cells.

16 cells is only roughly 1600 watts. You don't need a 22xx motor for only 1600 watts. A "L" or "XL" motor will handle that just fine. Once you start going above 2000 watts, then the 22xx series starts to really make sense otherwise, it's more motor than the batteries can handle.

I see your point on that lipomaxx. I think though 1600 watts from every motor is not equal. The 22 series puts out more torque from a larger diameter armature. There for it will pull the heavier trucks with ease on 16 cells.

He wasn't much on rc, but i'd be grinning and saying COOOOOL.

;) I've alredy seen him and I bought some remedies for my B4 as well( 14 IBC3800 cells). The buggy will surely be a big shot when I put in my 1930/5 and the new 18.149 esc that I've received yesterday.
I think the 22 series can handle from 6-30+ cells which can deliver up to 3000 watts or possibly more.

Whats so magical about 1600W? Would a 7XL be capable of that?

The 7Xl is over 1600 watts and the more the watts the cooler the motor and the more effecient it is.

More watts doesn't necessarily make a motor run cooler. To a point it will, but once you pass that efficient point (like during peaks), it is just going to heat up.

Yeah, but not as hot as a low turn motor. One of the advantages of having a high turn motor is that you can use the extra torque for more speed through high gearing. My 1920/8 does not heat up as fast as my 1930/5, although I'm using a gear ratio higher than the one I use for the 1930/5. So I guess that I can make it in the same league as my 1930/5 if I can use an insane gear ratio and extra cells. Lower turns are not always the best way to be Fast. Thats my own thinking and you can correct me if I'm wrong. The 1930/5 needs a highend esc to make it go insane and that is why I spent so much money to bring the 18.149. I hope it will perform as expected.

Using a slower motor and higher voltage is always the best way to go. That doesn't necessarily mean that it is the most practical way. When you add more voltage instead of amps, the motor will automatically be more efficient (as long as the gearing is appropriate). And because of this, the motor can put out more power without heating up as much. So, if you have a slow small motor on high voltage, it can actually produce just as much power as a faster, larger motor (when both motors aren't running hot). This does not say anything about torque, however, because the larger a rotor, the more torque it can output (the kt value is higher).

When I had the 1930 set at 5 turn, I wasn't very happy with the performance on my emax... Why don't you run it at 9 turns... and 18 cells.. that's a much better setup, IMHO...

it's only an extra 6 cells... :) but a lot more power I think..
one of the 1930 @ 9 turns, and 18 cells.. is more punch than my buddys Savage with an RB TM28...

I used 22 pinion, and 64 spur...

Surely it will not aqwut, because you're running it in a heavy machine unlike my lightweight B4 buggy( very light weight, actually).

M. Man: we are finally in the same line.

It'll fly on the B4...
When I had the 1930 on my Rusty, it was Extremely fast.. Rolling wheelies at any time.... 18 cells.. on it too.. but the CVD's couldn't handle it when I just punched it...

That's what I'm fearing. Probably I should take it to a lthe shop and ask them to make me a dogbone of thicker diameter.

Could you get some different cups and put on them? If you know the shaft size maybe we could help.

You have any suggestions?

rcalloys

get them to make you an 8mm shaft.. with a ? mm hole in the center.. then braize the cup part of the cvds onto the dogbone...

Thanks, I'll look into it.

The 2280 -5 turn, can the windings be changed to 9 turns .. or is it stuck at 5 turn....? anybody have any idea?

that's impossible, it's a highamp version. But why on earth do you want a large motor like that with such an absurd high kv range???!!! get a much, much lower kv range you simple need to gear it different.

I am sure that with the appropriate batteries the 2280/5 will draw 200 amps+ on 24 cells allready..

You need to reconsider that kv range, and change your gearing, perhaps getting the motor directly to the inputshaft or get a centerdiff, you can use a much lower gearing with that torque..Those large motors can't be compared to the micro 1940's you had. the torque is huge.

You could consider that high kv rating if you are planning on running 20-22 cells..

think different with those large motors.. it no longer is a hunt for high rpm's. It's all about the torque!

It no coincidence that the rpm limit is 42000 rpm on the larger BK controllers.

The post wasn't meant offending in what way ever, don't get me wrong awqut..

;)

so I guess the answer is no.... I was planning on connecting it directry to the Tranny Shaft for the Maxx....

using a boat coupler.... 5mm to .130" or .150" or something like that...

2280-5's gonna draw about 90A's at most... with 12S lipos....

It'll be fun to see what this sucker can do... BK's site says that the hi-amp motors are fixed..... but the're wrong abou t the 1930-5 turn.. I was still able to change the winding..

I hope they're wrong about the 2280-5 turn too...
1480 kv-rating is good enough.... I have a 42 spur and 20T Pinion... so far.. from SDP-SI..

you think 1480 KV rating is too high?.. I don't think the motor will ever be running at 4000 Watts unless I"m trying to push a house or something like that.. :)
hahahahaa....2000 Watts is enough to make it fly....

2000 watts can be achieved with a 7XL allready...

the 2240/12 of Promod took 3500 watts allready.. (On a 9s only...) go figure..
(that motor has got a 1233kv range and about 70% of the rotor size of the 2250)

AND it was with 4.25 to 1 gearing ratio from the 'center gearbox' (51 spur and a 12t pinion)
