Medusa Motors, anyone using them?

[Darin Jordan]

That was my point...need real world stuff. I do think a step up from china motors.

Not questioning the quality... but I question the claim... Only some real, scientific style side-by-sides will tell for sure...

And, of course... you have to prove they have an on-the-water advantage over our "cheap Chinese motors"... That may be tougher than you think...

I doubt it!!! The cheap 2 pole motors including the fiegaos cannot carry the pants of this 4 pole quality motor.
I will bet you darin a dime to every on of your dollars exact comparable motors matched up in the same setups will toast the feigaos or any other china motor.
You are trying to compare kias to lexus
Car guys have already learned this and boaters will too soon. These motors are speed rated to 60,000 rpms. Hardly a league for the china motors including them all.

Bring them on... Already seen them in boating action... and they didn't do what they claimed... being, swap out a Neu for a Medusa and go as fast... not even remotely... HOWEVER, I'm open to someone proving that wrong... Go for it!

Then... We'll compare an equal application to one of the even "cheaper" "Chinese" 6-pole motors...

By contrast... I HAVE run a Losi Xcelorin 1/8th scale motor, which is a 4-pole, similiar in specs (almost identical) to a Neu 1515 1Y... and it DOES perform nearly as well... maybe even on par... 8mm shaft, turned down to 5mm on the output, so BIG bearings... quality windings... 4-pole design... OSE Neu 15-series water jackets fit perfectly....

So... test these Medusas and let's see some numbers... The more choices the better in my opinion... but don't waste our time with claims and bad-mouthing the motors some are running with decent success, until you have something to back it up in the way of real data!

[crrcboatz]

you cannot provide a single EQUAL comparison of the medusa to the neu. You may have had similar but not the same.
In order to compare the same lets use the 1400 series neu since they are 36mm dia like the medusa. Put one of the 1400s up to the medusa with same kv specs and you may need to back down on your quick tongue. I just love it when guys want to compare the neu but don't want to compare apples to apples. The 38.9 dia gives the neu a bigger mass.

Now the above motor the Losi is the same way it too has a bigger mass via diameter 39mm. I own one and have used it in a car. Nice motor but not 36mm as is the medusa.


You neu guys love to say you have the best but then you don't seem to want to compare apples to apples. I guarantee you Darin you have NO like comparisons to talk about.


By the way Darin do you own a medusa? I own a medusa, losi and a neu 15152.5d. The medusa 36x80 is 1600kv the neu is 1650 kv and the neu simply cannot keep up with the medusa BUT then that is not a fair comparison because the medusa has more mass.

[crrcboatz]

The medusa will eat fiegaos of breakfast hands down with equal sizes compared. Remember the medusa motor can go up to 10s and in some cases 12s with no problems. A fiegaos will be long since in pieces or melted by then.

[Darin Jordan]

I guarantee you Darin you have NO like comparisons to talk about.

Curt

You can't "guarantee" that...

And... by the way... I'm not a "Neu" guy... I own two of them... One N2 setup, and one P setup... at this point.

Everything else is "Cheap Chinese Crap"...

Bring on the Medusas... Like I said... the more choices the better...

BUT... leave the BS empty claims on the bench... Because until someone provides some real data... it's all just that, and these are just another decent motor option.

[crrcboatz]

By the way I made a mistake in one of my earlier posts the neu is 38.9mm dia not 36.8mm dia. BIG DIFFERENCE

[Jeff Wohlt]

Meduas motor is this. The Losi says 12 cells max this one can take 30V so you may be able to run this one at much higher rpm and still have torque.

And at a whoping $120

MR-3670-2000V2SE-5
2000RPM/V
2.60A 0.005
1100W

Beats me but they did have some older stuff...this is suppose to be the new line of V2...whatever the hell that is.

[Darin Jordan]

The Losi says 12 cells max

For the sake of accuracy... the Losi says "2s to 5s Lipos"... I've had the motor apart... it's VERY well made... and is easily the quality of anything else out there...

But then... apparently we aren't going to compare these to the Neus or the Losi motor even, since these are a larger diameter...

So, the comparison to a "Neu" shouldn't have ever been made, especially since VERY few, if anyone, runs a 14 series Neu in a boat...

If the comparision is to a "2-pole Cheap Chinese" motor... then we aren't exactly comparing "apples to apples" there either, are we... or is the Medusa a 2-pole motor as well???

Let's get the story straight before continuing this dialog...

I don't care either way, because if the claim is that this motor can whoop up on a Faigeo, then BIG DEAL... how hard is that to do???

It's AWESOME to have more options... but perhaps let's keep things in perspective a bit...

If I am wrong in the comparison issue then prove me wrong. I remember your earlier comments on this subject and you were NOT comparing apples to apples. You compared a 36x60 medusa to a much larger neu.

Tell you what I will do, I send a new in the box 36x80 neu 1600kv to anyone you want. You do the same with a 36x74 feigao same kv rating or within say under 100kv, put them through any test they want. The owner of the motor that wins keeps the other motor. Mind you I am offering up a $145 motor to loose against a $80 motor.

[Jeff Wohlt]

Here is a well documented and tested comparison on a NEU and MEdusa and Mega

I agree with you on this. However, a 36x80 medusa will eat it for breakfast. I have a good friend in Pa. that owned both motors in a losi 8. He said it was not even close. the medusa literally tore his car up in less than an hour. Gears, shafts, hubs, were all un usable after an hour of racing. He is the one that put me onto medusas.
The losi is a good motor but cannot produce the power of a 36x80 medusa. Again the losi cannot use 6s and up power as the medusa can.

[Darin Jordan]

DUDE... again... the LOSI motor is only 66.6mm long... By your own words... this isn't "apples to apples"...

If you are going to criticize for not making equal comparisions... then live by your own standards...

ANY of these motors, if the same basic size, length, diameter, number of winds, etc., will make roughly the same amount of "power"... How they deliver that power might be different, but the overall power will be the same...

As a perfect example... A UL1 motor and an SV27 motor have VASTLY different KV, but are about the same size, same poles, same weights, etc... the only real difference is the KV (number of winds...)... One is about 1550KV, the other is about 2000 (as pulled from my Test bench)...

During a 1-mile race, however, if both are propped correctly, they end up using EXACTLY the same amount of mah... (i.e. POWER)... and, are going similiar speeds... I have race results, data, and eye-witness testimony to prove this point...

So... while the Medusas MIGHT be made with better materials... and they MIGHT be made to higher tolerances... If all else is equal, and they are of a similiar weight, size (diameter/length), and KV to another motor, the differences in performance are NOT going to be "eat you for lunch" style differenences... they will, instead, be a 1 or 2 or even 4% increase in efficiency, which will translate into slightly higher speeds, and lower temps...

ALL GOOD, but NOT what is being claimed...

Now, if you want to continue claiming that they will, for example, eat a 13mm shorter LOSI for lunch... then, well... I'll have to concede...


Again... I'm NOT saying they aren't good motors... I'm just saying that there seems to be a lot of "hype" in the claims of what otherwise might be considered a little "too good to be true" increase in performance...

[Jeff Wohlt]

Pretty good info here as well.

I now this is not our racing area but seems the reports on the V2 motors are pretty good. But you must compare apples to apples as Curt said.

[Flying Scotsman]

Curt, you old f*rt listen to what some seasoned racers are stating. The proof is in the pudding and I have never seen a Medusa motor mentioned in any documented runs for a podium finish.
