Medusa Motors, anyone using them?

[Darin Jordan]

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.

This really says a lot to me... from the thread Jeff references:

"You don't really need the added efficiency of a Neu in a light 2wd buggy/truck."

[Darin Jordan]

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.

Douggie,

To be fair... they MIGHT be a decent motor... I'm not questioning that... but until the claims of superiority over what is generally acknowledged to be one of the best motors in the business are proven... I'm questioning the hype...

Tough to find an "apples to apples" comparision in a boating app, however...


By the way... Neus are one of the motors of choice by Boeing and the USA for the UCAVs...

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...

Hey that poor little losi is 39mm in dia. vs the 36 on the medusa. Also the losi is a 6pole motor vs the medusa 4 pole. I agree the comparison is not fair in terms of mass, but the losi should be more effeciant just as the medusa is vs the feigao.
Medusa motors have buttloads of torque and run super cool compared to like rivals. That lets them do a lot of work without taxing one's batteries. The medusa will run sometimes 10+ degrees cooler than a similar sized neu.

Also the losi is a 6pole motor vs the medusa 4 pole. .

Again... ACCURACY to the claims counts!!

The LOSI is, in fact, a 4-Pole Motor... AND, 13mm shorter... so of COURSE it's going to have less torque...

Here... so there is no more question about the LOSI:

Darin, spot on. They MIGHT be better, I doubt it but the SAW boys normally solve that question, as for normal racing/sport boating???

Douggie,
Hey since our past is behind us, I accept being an old f**t with distinction! thank you very much. I consider you a very knowledgeable boating friend now. Hope I am not being presumptuous.
I do think there is a day coming when the podium thing will change! Medusa has a growing future in product choice and records. I see it this way, crawl, walk, run. In its early stages now, medusa is crawling, it WILL walk, and I believe it WILL run in the near future.

As far as one getting "what they pay for" how is it that the Plettenberg as many neu owners believe, is not as good a motor for the high price one must pay for it vs the neu??

I see that in the same light as the medusa vs the neu in bang for the buck.

Curt, very true all manufacturers learnt from their humble origins, and from one old f*rt to another, you were not presumptious, you were seeking the truth.

Boeing also chooses aveox motors and they no longer make rc brushless. Didn't neu buy them to IMPROVE their line

I have not said the medusa is better than the neu YET. I will say the day is coming when neu will quite frankly, have a most worthy competitor. That is good for all of us.
Neu had to start somewhere just as medusa has. In my opinion, give medusa the same # of years and they too will be right there. Out of the shout, however they are more than holding their own.

You know this subject intriques me. In Formula 1 racing a team BRAUN RACING is dominating at this time with an aero package that has left the others breathing dust. It is not the motor, at all times. Mclaren have the same motor...Mercedes..not too many points for McLaren with a world champion for last year showing his true potential.

WOW! A lot has happened since the birth of this thread a few days ago, looks like a few differing opinions to say the least . I think the only thing that's missing is some practical application so I am going to "give one a go" and report back, however I could use some suggestions. So here's my setup;

29" sprint cat
4s 5250 30c
.150 flex cable (i was going to use .187 for the NEU 1521 1.5D originally)
CC 240
varied props X440, X642, 38X55, M440-to start

Here's the link again for reference, thanks everyone for your help-

I was leaning towards the 36-80-1600 OR 2000?? Too much, too little??

[crrcboatz]

well, I went the whole 9 yards and ordered a 3670 2300kv for my whiplash 20, and another 3680 that is a kv of 2000 for my 32 inch maus bullet mono. I also have a 3680 kv1600 I will put in my 34 inch titan and run it 5s or 6s not sure yet. The other 2 will be 4s so we shall see. I am now the new, one and only Medusa powered fe boater I think! lol. The Medusa Guy kinda has a nice ring to it. Will also need to develop a logo and colors for it too, you know go all the way!!lol again.

Hey Medusa Guy- There is another guy running a UL-1 with Eagle Tree Data, he will run the 36-60-2200 on 4s so should be interesting to "see" the actual data on this motor and setup. I'm going to give the 3680-2000 a go in my sprint cat on 4s.

[RPC1]

I have the 3670-1600 on 5s in my Whip 20 and a B/S DT X642.

[Jeff Wohlt]

Excellent...thanks for taking the plunge, guys. Please keep us posted.

intriques (is that Scottish English m8 ) i think you mean intrigues
