Hi Omegaboy go to www.razormotor.com He only sells direct, I have the 25oo razor on a scratch built RCM scooter gear box 6:1 with a Hobby Lobby 10X6 three blade it is awsome. a And I think these are the best motors in there class, I have at least 1 of every brushless motor out there, by far Razor runn the strongest.

omegaboy,

Please note that Matthew Orme, who owns and operates Razor Motors, is having
severe problems of a personal nature which interfere with business at this time.
You would be well advised to purchase a used Razor motor in excellent condition
from a reliable source. Hope you find the right person, good luck.

Hi I'm from Ok also. Saw your post this morning as I was doing a search on razor motors, I bought an older 28" eflight ultimate at a swapmeet Saturday that has a razor 2500 with gearbox on it and I was trying to find out a little info about it. Such as what battery pcak I should use, and recommended prop size, etc...
Also, I am in Tulsa, are you close to here?

We (Neumotors) took over building Razor motors from Mat several years back. You can find them for sale at our web site:http://www.neumotors.com/Site/Motors.html

Wow guys
:eek:
Your website is pretty screwed up. :o looks kinda like my last blucor wing, twisted, text on top of text, things of that sort. What would be a good low speed 3d prop for a geared rz2500?

I think you web browser program is the problem.....

You should see something like this.

Steve's web site looks better than good to me - nice layout too.

[j4ck4]

Thats cool

First page looks like that, your right. When I go to the page that has the rz2500 that I wanted info on though it shows the below, don't know what the problem is. I do web design and IT work for a living, but that aside. I just wanted to let you know that you might need to llok at your code a little closer. Did not want to stir up anything, I to think the site looks good, I like your choice of colors and text font. Anyway thanks for the response.

[Dr Kiwi]

I'll agree -the website is looking better and better. Steve, you have many of the vital specs, but is there any chance you could include max. amps and max watts for each of the Neu motors?

[Jeffery]

is there any chance you could include max. amps and max watts for each of the Neu motors?

For how long? 1 second, 30 seconds, 3 minutes? What amount of cooling? None, open air, forced air? It gets kind of hard to predict how somebody will interpret the information, really. You can go Here (http://www.castlespecialprojects.com/) and see some expanded info.

I get the same. Firfox 3.0.6, Macintosh Power PC..

I think the issue is that the container <div> for all that text is specified at too small a height: IE seems to let text run over..Firefox and others try and squash it in. It's likely that its also useing a slightlty different font.


That the trouble with Application builders..they sometimes get it wrong..whereas if you hand code you ALWAYS get it wrong, and so have to test against many browsers.

[Martin_G]

Hi,

The same for Firefox 2.0 and Konqueror 3.5.5 r45, Suse 10.2

Imho that's OK...Firefox simply does, what is written in the code...
style="line-height: 16px; "for the upper 3 Motors,


style="line-height: 5px; "andstyle="line-height: 15px; "for the 4th motor

servus,
Martin

All I really wanted to know with my first post was what prop I should use with an older rz2500, and what would be the best battery on a 28" ultimate with a castle 25amp phoenix esc.
There are some div problems on the site and coding is always hard wheteher you hard code like I enjoy or use Dreamweaver, forntpage, expression web, or a linux or mac web design program. I started out in web design almost four years ago and learned to hard code the hard way, get on the internet and find out what you need to make your page do what you want plus read all the books you can find on the subject. I didn't intend my first post about the website as a direct attack on anyone, but only to let you know there was something wrong with the site display Steve.
Hope IO can still get some help with my original question as it seems to have been forgotten, and it is the info on the motor I have that is skewed. Also can I get a prop shaft for my gearbox? It has D gearing.

Ok SNEU guess you stopped following this thread or you just don't want to answer my questions since I said something about your website that you didn't like. Guess its good business in some places to blow off potential customers because they say something you don't like.
As I stated earlier, what I said about your website having some problems wasn't meant as a personal attack. Heck I've had people say a lot worse things about some that I have built for people. It is one of those things that goes with the territory. So, anyway maybe I should just trash this razor motor. I can't seem to find anyone that has a lot of good things to say about them anyhow.

I don't follow things that close--and from your post there is did not seem to be a clear question....Prop and battery are up to the users--but 2-3 S and up to 20 amps current are reasonable limits. You could of course use one of the online calc programs like this one to find out what might work for your application. http://brantuas.com/ezcalc/neumotorscalc.asp

The information for the Razor motors in included in the data base .

Well, your posting your questions in the "Electric Motor Design and Construction" forum. This forum is more for electric motor design and construction than it is for discussions regarding motors that are already designed and constructed.

If you were to hop over to the "Power Systems" forums (one forum below this one on the main page), you'd get a LOT more information about the Razor 2500, including feedback from many people who use and love it.

As for "the best battery", nobody is going to answer that. Do you mean "best brand" (very subjective), "best capacity" (maybe a decent 1300~1500mah), "best cell count" (probably 3S for a 28" biplane) and then we get into what prop you're running. But this gets confusing because you also mention a bent GB shaft with "D" gearing. Is the Razor in a grey plastic GWS gearbox with the GWS "D" gearing? This will have a lot of beaing on selecting a prop.

So if you are miffed that nobody has jumped in to answer your question, just remember that you have posted some pretty vauge questions in the wrong forum.

[birdie_in_texas]

jEEBUSS..!! A 2500 in a "D"..? NO..!! DON'T DO IT..!! TOO MUCH POWER..!!!! hahahhah

Needs to go in a MUCH better gearbox...like for instance, the Cobri..:)

And the Razor 2500, old or "neu" is a bad ass motor.. ;)

Well excuse me gentlemen, I guess Jeffery told me. I must be stupid or something I do a search here in the forums for a thread on Razor motors, and then post a ? about one on that ssame thread and I'm a dummy. My bad. Guess I need to appologize to the entire rc community for that . And Jeffery I wasn't miffed that noone had answered my question. It was directed to Steve the guy that had posted the following statement:We (Neumotors) took over building Razor motors from Mat several years back. "You can find them for sale at our web."

[Jeffery]

I wasn't implying you were stupid, just that there is a LOT more information on the Razor 2500 in the Power Sytems forums.

You found this thread, that's a start, but not really the best thread on RCGroups.

For instance, I did a search for "Razor 2500" in "Power Systems" (http://www.rcgroups.com/forums/search.php?searchid=18618331&pp=25)and got 23 pages of hits, 573 hits in that forum.

And sneu does make Razor motors now, but he'd have no more idea than anybody else about answering the questions you posted. I'll wager he's never even ran a GWS gearbox (if that's indeed what you have, we still don't know).

So before you toss that old junk Razor 2500, why not at least try to get a little more info in the "Power Sytems" forum?

P.S., they are excellent motors. I own several Razors, just no 2500's. And Birdie is right, the GWS gearbox (if that's what you have), ain't all that. The Cobri, on the other hand, is excellent.

[j4ck4]

Thanks Steve

You know what I guess I'll just go with trial and error on chossing a prop and battery. I just thought maybe someone could recommend something that I could fly this thing with and be able to still keep up with it on the sticks I just started flying rc about 4 months ago, and I've went through several scatchbuilts and enjoy them, I would like this thing to fly slow and maybe try a few 3d maneuvers with it.
I guess my question about the battery would have been better stated as what should I go with for low weight?
Oop's I'm still in the wrong forum. Guess I better move my self outta here.
Yes, it is a gws gearbox and like I stated I just bought the stinkin plane and was trying to get some help with what might be a good setup for me to learn with.

[Jeffery]

Post wherever you want, I only suggested that you would get a LOT more responses in the "Power Systems" forum. That's where almost all of the discussions concerning "Power Systems" are, this forum is more tailored to the design and construction of motors, and you aren't trying to design or construct a Razor 2500.

As for trial and error, that's all you can hope us to guess about if we don't know the actual gearbox. I'm guessing it's a GWS plastic gearbox, but without knowing that for certain all I can do is tell you to go the trial and error route.

I bet the guys who hang out in "Power Systems" might be able to help, unfortunately, they'll likely never see this thread.

A 2S 400-1300 mah 15-20C battery would be a good choice for most smaller planes.

Thanks again, Steve it has the gray plastic gws gearbox the shaft that is bent is the main shaft in it, not the motor shaft.

[sneu]

You are on your own for the GWS parts. We don't have any info on them. If you know the ratio you can still use the motor calc program to get a idea of how it will run.

[Jet Dreams]

sneu, I have been out of the electric seen for a few years. I just have to say I am so glad you are building the razor motors as I almost shed a tear when I found out I couldn't get another razor 300 years back. I just loved that little motor.
