Tell me about Medusa motors for 1/8th
 

I have been brainwashed that Neu is the "Messiah" of 1/8th motors so that's what I run in buggy and truggy. I have been looking to p/u a back up motor and have started to notice more about Medusa's and wanted to see if I could get some cliff notes on these lower cost motors. I know this is a general question but I wanted to get another thread in the Medusa forum. Thanks for any info.

From what I have read here, the Medusa line is a very good motor....used by many forum members. I currently have a 50 series in my daughter's crt.5 and it runs flawlessly. When funds permitt, I will be getting a 70 series for my Revo convesion. For the money, you can't really go wrong.

I have a medusa 60 series in my crt.5. Its a great motor, everything stays cool.

The only motor I like better really is the Tekno Neu. They are really smooth.

The medusa's, older Neu's, and CC Neu's are all very notchy (to me) when they are off the throttle. I dont know if that makes sense to any one else, but if you spin a tekno neu in your hand and then a medusa you can definatly feel the notches in the medusa over the tekno. I dont think it hinders performance in one direction or the other, but I like that the tekno one stays quiet when the truck comes to a stop.

I noticed the same thing as I run a tekno neu in my 8T. Definitely smoother when I compared it to the 36/50/1600 my bro has. Since I use the Tekno clutch system I realized it didn't matter as I don't get motor resistance when the clutch disengages.

It looks odd when I compare the 1512 Neu to a Medusa 50 or a 60 and realize the size difference. I am thinking I might hurt the Medusa motor and how can this little thing power my car. But it obviously can since others are using on their set-ups.

Neu motors are as good of a motor as you can get right now, but for the price you can't go wrong with a MedUsa motor. I currently have 3 of them and all of them perform flawlessly and outperform any other motor I've seen in this price range.

Medusa's are awesome motors whether you factor in price or not. We had a 50/2200 going strong in a buggy for months. We changed the setup a little bit ago, but only because we were testing setups. The 50 is the same size as brushed motors, it doesn't make any sense, but it pushed that 8lb buggy around just fine. The 60's seem like the best balance of power, weight, efficiency, and cool running for a buggy though. If you're just racing for 10 min or less, you could go with a 50. 70-80 for truggies (although we had a 60-1300 on 6s in a truggy for a while too:)

I have a 50/2200 in my .5. I've had Neus and Tekno neus and LMTs. This is as good as any. There are just a couple of things that make it a bit cheaper, but really its not to much of a diff. Lots and lots of power in my .5. Definite Best Buy

I have a TeknoRC Neu 1515 1y and a Medusa 36-70-2000Kv. The Neu is on my ST-RR while the Medusa is on my revo conversion. I like them and both are running on 5S. In my experience, the Neu is smoother and a bit powerful than the Medusa. However, the Medusa is cheaper. I can get 2 Medusa motors for the price of one Neu. Best bang for the buck motor.

You can't go wrong with either of them. It all depends on your personal preference and depth of your wallet.

What about temperture? How does the Medusa measure up compared to Neu? I'm looking to get a 80mm for a 16lb monster, can I expect Neu type temps? Or at least close?

The Medusa I have runs cooler than the TeknoRC Neu I'm running on my truggy. My trucks weigh almost 10.5 lbs apiece so I don't how a 36-80 will run temp-wise on a 16 lb tank.

Keep in mind that Medusas are 36mm diameter and Nue 15xx series are 40mm diameter (~44mm with fins). So, a better comparison would be between the 14xx Neu series and the a Medusa of the same length kv..

I've had great luck with 36-60-2000's in my buggies running 4S & 5S with the MMM. Great motors with a great price.

I got 160 degrees on my 36-60-2000 when running without the heatsink, is that normal? Never topped 130 with the heatsink on, should it make THAT much difference?

If the set ups are the same, the heat sink will make a big difference.:mdr:

What is your set up, more info could be helpful in possibly lowering temps. even further.

I have had a 36-60-2000 with a RCM heatsink/clamp,and a .5x2in. slit in the bottom of the windshield for air in my FLM E Maxx with a mmm on 4s. Geared for 40mph it hit 160f one time when I was running through snow spinning most ot the time. I have run SPC 8000mah packs till cutoff on a soccer field non stop and am lucky if it hits 130. I just put a 36-70-2300 in it and have yet to run it. My Neu 15151y smooth can tends to run about 10f hotter in my x1crt on 4s geared fot 40. From what I have read and seen for my self I would get the medusa and use the saved money for other upgrades.

I just got my Raze Buggy running this week and it has a 36-60-2000 Medusa in it that I will be testing a few differnt esc's, batteries, and gearing with. I'm going to keep the gearing for ~40mph maybe 45mph (maybe a few speed runs if the motor stays happy) and check temps all around. I don't yet have an eagle tree setup, but will soon.

Right now I've ran the buggy on 5S and 6S lipo with temps no higher than 110f on 6S after a 10-12min run of mostly WFO (for those that don't know that mean full throtle :angel: ).

ESC's I'll be running it with are the typical MM/ bec on 4S, MMM on 4S -6S, and a hobby wing 80a on 4S.

Anyone here using 80mm 2200kv with 6S?
Im thinking about stepping up from 4S to 6S, to get even more raw power.

I know the 70mm may be more ideal than the 60mm for a Revo but how much of a difference? I'm looking at 1600kv on 5s. I'm setting this up more for racing now but will bash with it as well. Tekno Neu is awesome but I think to much for the track. Last week I threw on my new bowties and hit up a very soft baseball field and all it wanted to do is wheelie! I'm gonna put my neu in a Maxx and want something with a bit less torque but that will still run cool. As I said this is kinda geared towards racing and I will never gear it for more than 40. Is the 60 enough or just get the 70?

Just get the 70....I run 60 in my buggy and it's ok in a 8-9lbs buggy. Most here agree on the 70 for anything over 9lbs. Some might even tell you 80mm!

Including my heavy lipos and 40 series tires with soaked foams (a pound or two each with the water in them) my Muggy is very heavy, probably 16 pounds or more, and with a 16T pinion the 80mm pushes it around like it was nothing. If you really want the 80mm go for it, but even in a really heavy Truggy it's extremely powerful.

Ok I'm no noon here. I know the 70 and 80 will do it without a problem, for me it's a matter of I think a 70 might almost be to much for the track! My neu I think will be too much as it will wheelie pretty much whenever I want. I don't want that for racing.

How would a 1300kV 60mm Medusa perform compared to a 70mm one in a Mugen MBX5 on 6S?

Tekno RC/Impakt RC ran one of those 1300 KV 60mm motors in a Truggy and it ran pretty well on 6s.


E-Revo: If you want to run a 6s setup I think the 60mm should be fine for your track. I'm running a 70mm 2000KV in my Hyper 7 currently on 4s lipo with the soft start on my MGM all the way up and my onroad tires can't keep up with the soft start :lol: It's only got an 18T pinion on it right now, probably move up to a 22T with as cool as everything runs (MGM is a little warmer than the air temp, the motor gets up to 90-100 after a full run, despite being Maxamps lipos they only get mildly warm).

I sent Mike an e-mail earlier on this because I'm pretty sure he ran a 36-60-2000 in his E-REVO. I already have a couple 5s packs and don't want to buy anymore lipos right now so I'm sticking with 5s. I hope that even a 70mm will have less torque than the 1515 neu since it's smaller in diameter.

IMO the 60mm would be fine in the E-Revo. There was a guy that got his E-Revo up to 52 MPH with that motor and it didn't cook it or anything. It should do fine.

i was thinking about getting the 36-70-2300 for my MP7.5 buggy

i wanted to make sure i got the power i needed at my track for the tripples. plan to run it on 4 cells. does that seem like an okay combo?

Should be good. I run my 2000KV motor on 4s and it goes pretty well. At 18/46 I still have room to gear up a ways.

cool, i will have to get into that calculator to get some good speed numbers, but i think that the motor i am going to shoot at.
