Medusa Brushless motors..36-80mm

[Ub Hauled]

Just a note regarding the watts stated in Medusa site for the 3680. The 1300 watts are for minimal cooling, with proper cooling these can be doubled. Just received their reply:
"The watts we list are for minimal cooling.
If you can properly cool the motor (i.e. airflow & heatsink or water jacket) you can pretty much double the watts.
So to answer your question, yes, if properly cooled. The motor case temperature should not exceed 180F"

I'm going to play devils advocate here for a second... why would a sales guy mention the above when the data sheet for the motor specifically says that:

*Based on adequate air flow around motor, i.e., open air stream behind propeller (P in)
**Max I can be present for 30 seconds (I max)

Answer to my own question: Because he's a sales guy.

That means that the 1300 is the max that it can go with proper cooling and not the
2000-2500 range you had asked him.
The 1521 series (comparable size to the 3680) is rated to 1800 continuous and 3000 for 30sec.
Again, I am playing devils advocate here, I too prefer a cheaper solution to power... but until I can find it, NEU motors are the best $$$/power deal.

Sorry but your assumptions mean nothing with regard to this motor.
1. you don't own one
2 Until you do and try it you have NO knowledge of its performance potentional, cooling /output potentional
3. Bashing a new product comes easy when you sit on the sidelines and throw out barbs casually via the assumptions route.
4. Buy one and try it! Are you afraid a Neu may have some competition?
5. I get SOOOOOOOOOOOOOOOOOOO tired of Neu being the only act in town. I may sell my 2215 recently purchased and get a Plettenberg just to show people a neu is NOT the only act in town.
6. I suspect Medusa is only on the cusp of producing an entire line of motors to compete with neu. Lets wait and see on that one.

Have you actually read what I said?!
Are you an employee of Medusa Research or something?
Dude, I am pro using cheaper motors with good power...
no I don't own a Medusa motor, but until I get my research done I will not own one... that goes for every motor I buy not only these. Had you read my post properly you'd have seen that I mentioned not once, but twice that I was playing devils advocate, had you known what that means, you'd know that I like the motor but there are (in this case) contradictions on information which created doubts in my mind. Do you really think I own only NEU motors? I happen to have a pile of motors that vary from NEU and Lehners to motors that don't even have a brand yet.
So, before you fly of the handle, make sure that you know what the other persons post means.

6. I suspect Medusa is only on the cusp of producing an entire line of motors to compete with neu. Lets wait and see on that one.

Good news...

UB, you are right. I could have given more thought to those comments. I accept responsibility for them and will read more and comment less I guess

Many times in this hobby the new product must prove its self. I remember when the Picco nitro marine came out and people were the same way about it vs the OPS. I bought one of the first and ran them for years because they kicked butt.
Recently I bought 3 rcmk gas engines and got rid of my zenoahs. for the same reason. The product is just plain better engineered and cost effective vs the zenoah old school theory, bang for the buck.

Variety and choice in a hobby especially in the power dept. helps to grow the hobby.
I for one would LOVE to see some viable choices to the dominance of Neu being the only act in town.

I am trying to share-exchange some information on a relatively cheaper motor than NEU and if it has a similar performance. I have seen a smaller one running (in Dino7 above) and it is going very very well in all terms. To be honest I don't think that an American company would claim things that their products can do but actually cannot. This means that I believe them.

It's all good, I too sometimes read things in a different mode then what the writer tried to express, you were "big" enough to admit it, to you sir.

If you are at all interested in a Medusa I would suggest reading this thread from RC Monster...its probably got the most information ever on the yay's and nay's of Medusa motors with over 600 posts and 23,000 views

I have read the whole thing and the general consensus is that Medusa is rock solid and very comparable except being much cheaper and having a 2yr warranty

my consensus is that if money is no problem than yes Neu has the prestige like no other but there are a few motors that can compare with it .........Medusa being one of them

great link man, thanks.

Here's my one experience with a medusa motor. I spent the money and bought a 36-50-4800 to compare against a 1509/1.5d. Similar size/mass/kV. On that particular boat I could run either an X438 or X637 no problem on the Neu. Thw medusa wouldn't turn those props. I changed shafts and dropped down to a cut Y535 it would run, but not at near the speed and significantly hotter. The medusa was water cooled and the neu wasn't, end bells of the medusa were still hotter than the Neu after a run.

Sold the motor to a car guy who loves it.

Just my experience, your milage may vary.

[Ub Hauled]

is that with the V2 Brian?

[raptor347]

is that with the V2 Brian?

Yes. I will say, they appear to be nicely made. The one I tried just didn't cut it. Someone else can spend the money to do further testing.

The neu is larger than the medusa. The 1509 is 40mm in diameter the medusa is 36mm.
The only 36mm motors neu makes is the 14 series and all 3 of those are 70mm in length vs the 50mm of the above medusa.
It is only fair to compare apples to apples the above experience did not do that.

Curt,
None of the Medusas can be compared to the NEU according to your remark, it actually voids all you said above... you'd have to compare some other 36mm motor, like hacker's B series for instance.
On that note, I just wanna mention that size is not all, take for instance the KB45 motors, they are 45mm and a lot of smaller motors can outpower them.

[Flying Scotsman]

I think the proof is in the pudding is what do tried and true racers use..in North America..Neu...Europe a different animal

Douggie

I believe it is only fair to do it that way. If not then compare a larger plettenberg against your neu. That would be fair in your line of comparingbut hardly fair to the neu, right.

Or better yet lets compare a 1509 neu to a 36x80 medusa. I would love to do that comparison. NOT a contest at all. If I put a 1509 on my monster truck and asked it to do what the 36x80s do it would be no contest.

For my line of thinking making things fair in a comparison is the only way or else there is no need to do it. One cannot slant a comparison with one motor being larger and expect it to be a fair comparison.
