Woohoo! My 36-80-1100 came in today! This motor's nice. Just wish it didn't have the cooling holes... Oh well. The flat spot along the entire length of the shaft sure is a nice touch.

nice nice you lucky bird

what batts you going to run that on?..car?...esc?

Savage with extended FLM chassis (not their tranny-forward chassis), HV-110 and mechanical brakes, and 9s1p A123 for now. I might reconfigure some batteries or do something and get 10s1p, but that will be a little later.

@Metalman - That's going to be an awesome setup. I'm sure the 80mm can will deliver loads of power. I was wondering why you chose the lower kv.

I noticed in the 70mm length, Medusa offers kv options all the way down to 380kv.

I wonder what kind of torque that motor has? :oh:

We are talking Rock Crawler kind of torque.

I also wonder if the shaft comes out the back on the 70mm motors like it does on the 80mm ones?

Jeez, 380 is a super low kv! That would be great for direct-drive-to-diff if the motor had a suitable output on each end of the shaft.

Hey no fair!! I had to make my flat spot!

Good to see everyone is getting their motors. Metal, did yours also come with the extended shaft in the back?

It sure did, and even that slight bit of shaft has a flat spot on it.

Mine finally showed up! Got a 70 and 80mm @ 2000KV, they both have flat spots already on the shaft and a little shaft coming out the back.

EDIT: I'm too lazy to pull the 50mm out of my CRT .5 to put up a comparison photo. I guess I could get one of them sitting by my 1515...

so how do they run?

The bad thing is there a holes in the back :(

All I can say for my 80mm is :surprised:

Turned all 4 40 series tires on my Muggy into pizza cutters, worked a screw in the the steering spindle loose, launched it into the mini bar making an epic THWACK, and popped a dogbone out :party::whistle: This was with a 2000KV motor on 4s maxcramps lipos :yipi:

Got 'em in the front, too. Avoid mud and clean the dirt out when they get dirty and it should be fine.

EDIT: One thing I'm shocked to see are the wires...They are the same diameter as the ones on my 50mm! I can't understand how those things can handle the power these can put out. The ones on my Neu are considerably larger and never got hot under extreme use.

Sounds like they're working great. I'm thinking I'm going to want an 80mm for my emaxx here in the near future. Still waiting for any sort of ship notification about my 70mm 1600kv. I was hoping I'd hear something before Christmas, but it looks like that's not going to happen.

Thank you very much Medusa! Box is right here in hand. sorry no pics yet. :)

can i use 36-80- 2000 with 6s a123 and MMM v3?

Yep, I reckon that would make a killer combo.

Im starting to wonder whether 1600kv or 2000kv would be better for my needs- 6s2p A123 or 5s lipo also.... :neutral:

I've got a 1600kv 80mm on the way for my muggy. I'm going to run it on 6S lipo and a MMM and try 6-9S lipo with lutach's 10S esc once I get a data logger to make sure I'm not drawing to many amps. Don't want to hurt anything.


-Brian

:lol: Good luck.

IMO the 1600 on 6s would be plenty of motor for bashing, if you slam it and go with street tires the 6-9s setup should get you 60-70 MPH IMO, depends on how well you can keep it under control.

How does Medusa work when those cooling holes are covered, as it cant cool down?
Im working on brake-adapter that has cooling channels in it, and it takes air in one specific place, that can be protected from dirt and dust. And for rear im planning "airfilter".
But havent got my motor yet.
e. I could just share my sketch, here.

The Medusa Motors were designed with Heli and Airplane Applications in mind.

When used in a Monster Truck or Land Vehicles, very little air goes through there anyway.

Inside the motor, the windings where the heat is generated, is in direct contact with the inside of the motor can.

Just a regular heat sink will work just fine, even with the holes covered. As long as your setup is geared right. :yes:

They work just like a normal motor when the holes are covered up. In an airplane there would be a prop in front of the motor and that would blast air straight through the motor. They run VERY cool in an airplane as you can imagine.

WOOT!!!! Finally my motor shipped. Sadly, I am in Portland Oregon right now and I live in Arizona, which is where it was shipped to, so I wont have it for until I get back. :cry::cry:

Very nice, I wonder if these are just the pre-ordered units or if they've started rolling them out on a regular basis. I really need to get rid of the 7XL in my e-maxx, it's just too silly of a motor to deal with.

Pretty sure they're dealing with Pre-Orders right now, I wouldn't expect them to be readily available for another few months. If you need a new motor check with Mike and see if you can pre-order through him. If not I think they are still taking back-orders on their website.

So I got one of the 60mm 2000kv motors for my D8. This thing has a ton of motor drag, strong magnets I guess. Anyway I'm concerned how the buggy is going to jump. Is it going to nose dive off of every jump or am I going to have to keep throttle in it to prevent that. If I do that now I'm concerned about stripping ring and pinion gears. I mean the drag is nuts, it feels like having worm gears in the transmission.

Anybody have one in a buggy, and how does it fly?

I have a 50mm 3300kv that was in my FLM build. I'm thinking that it probably weighed as much as your D8 when fully laden, and drag wasn't really an issue. If you push the car by hand, you'll notice the drag disappears once you get it rolling. I had the same notion with both the Medusa, and more recently my Mega 22/45 which is a 6 pole and notches worse than a medusa. But its negligible when the vehicle is actually moving.

What about in the air though? Guess I'll go get it dirty if the track dries out today and report back.

Ok, went to the track. No nose diving, absolutley awesome motor. Perfect speed on 4s 6000mah geared 15/48, 20-21 minutes. Highest temp was 160 deg at the 20 minute mark.

Was thinking this would be awesome on 5s with a 13 tooth pinion, now to find a 5s that will fit under the body and yield a 20 minute run time.

Toljaso :)

Medusa 80mm motor
 

So anybody tried running the Medusa 80mm 2000kv motor? Any good or bad things for this motor. I'll be putting this on the Lst2, maybe 6S on MMM V3. thanks.

Probably wrong thread but maybe someone with more knowledge and experience can answer this. What would be a more efficient motor, Medusa 60mm 2000kv or Tekno Neu 1515/1/Y/F (2200kv)? Medusa geared with a 15 tooth pinion, Neu with a 13 tooth pinion on 4s.

I run the 80mm in my Muggy and it's insane. You may have problems snapping tranny pins in the LST2, it is really powerful. It is definitely powerful, I'm going to gear mine down a bit to keep the amp draw down though. My MGM 16018 gets a little warm with this motor.

They are both pretty efficient motors. It depends on the vehicle as to what would be more efficient. The Neu 1515 series much bihher than a 60mm Medusa. That 60mm Medusa would prolly be more efficient in a buggy than the Neu, but in a truggy or MT the Neu would be more efficient because of it's larger size giving more torque to move a heavier vehicle.

Ok, thanks. I have ran about five packs on the Medusa and love it. Now to find a 5s that will give me 20 minutes and fit under the D8 body. I'm thinking the Hyperion 4350mah would be enough, but not sure. My Polyquest 4s 6000mah gives exactly 20 minutes.

80mm Medusa
 

Thanks for the info unsullied Spy. I have a 1527 1D 2200kv Neu but have problems with ESC burning up, Now I bought a 22418 MGM but I'd like to put a MMM and the 80 mm Medusa in it.

No prob. 1Ds typically pull a lot of amps. It's best to go as low of KV as you can and run higher voltage. Your ESC will handle 6s, so a 1600KV would be best. The 2000KV motor is fine, but the 1600 will run cooler and pull fewer amps. I had a 1515 1.5D in my Muggy and it pulled a ton of amps, I could thermal my 16018 in just a few minutes if I pushed it hard enough.

What sort of amps are we talking about, for the 2000kv 80mm medusa on 6s? I've got one of those ordered, but I'm going for longer run times, not crazy insane speed, so should I see if Medusa can change it to a 1600kv?

Anyone feel like getting me an EagleTree or Oracle as a belated Christmas gift? :lol:

I'm not sure exactly how many amps, and it all depends on your gearing (you pull a lot more with taller gearing). If you would prefer longer run times the 1600KV would be a better option. I wish I had ordered it instead, but I got the 2,000 so I'm just going to deal with it. It's not bad or anything, but the 1600 would be better (I'm currently stuck with 4s lipo, so it's kinda a good thing I got the 2000).

Yea, I'm in the same boat. I was going to run 5S LiPos which is why I initially ordered the 2000kv, but having read up I think I'll get a bunch of 3s 4000/5000mah packs and run 6s packs.

I've been looking at the Oracle System.

How is it compared to other data loggers?

Where can I see a screen shot of the software? Thanks

http://medusaproducts.com/oracle/index.htm

Specs are good, I think they're comparable to a EagleTree. I've heard that the resolution is really good on them, better than an EagleTree. Not sure where to find a screenshot of the software.
