Medusa Motors, anyone using them?

do you have a link to the website ?? Thanks

Not sure if OSE allows it here.

Here is a good review of them. I'm going to take the plunge and order one. http://www.e-savage.com/forums/showthread.php?t=2648

Did you have a custom motor made to order?

No,just a 80mm 1600kv and a 80mm 2000kv...

those Etti coolers work well,i have 2.
Just smear some vaseline jelly on the orings when fitting,it also seals the can better.

...this is fun to read....

Here's mine after one weekend it didn't even make it to the 1 min. to check temps. I was testing prop sizes. The cap fell off on one run temp was 110 on motor I put the cap back on. Then went up 2 sizes on the prop and this is what happened after 40 seconds. I hope they have good CS or there goes another $100.00

[LuckyDuc]

Wow. Looks like the thrust of the prop/shaft pushed the end cap off. Were you running a thrust bearing between the collet and motor?
That same thing happended to my ARC motor. Thrust bearing prevented it from happing on future runs.

[B-DAWG]

No, I wasn't using a trust bearing. You think that is what caused the cap to come off?

[LuckyDuc]

Most likely.

[Brod]

Oh dear,that dosnt look good.
My 2 motors havnt come yet,i'll be using thrust bearings.

I had two runs on Sunday and they were great as before. Running ard 45mph. Eagletree graph of both runs as attached.

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

I can say that we did not buy the Aveox line of motors.

A little history lesson is in order. I have been friends with Dave from Avoex for a long time. We did help each other with brushless motors and controller designs over several years. I designed one of the early sensored controllers for Aveox. The 1.5 inch diameter stator motor which seems to be the subject here was never produced by Aveox. It was a result of work that we did to try and improve efficiency of their 1.4 inch hobby design. As we all know the design worked out quite well.

When Aveox decided to exit the hobby business in favor of the aerospace world I decided to get into making hobby motors. We took the 1.5 inch stator that Aveox and I had developed and used it in our line of motors. 2 years ago the 1.5inch motor design underwent a major refinement which resulted in improved motor efficiency and lower cogging.

Neu magnets are outsourced from China also. Would bet the wire is not usa either. Labor is US but who says the US has a patent on building good bl. motors. Plettenberg, and lehner are not made in the US either. Etti escs are not made here either, in fact I bet they are made in China with a european name put on them.
The main thing in outsourcing is QUALITY of parts that are used. Quality control is the key in picking the materials.

Food for thought

Magnets from China
Machine parts from USA,China and India
Stator steel from USA or Germany
Stator stamping from India and China
Bearings from Japan and China
Motor shafts from USA and China
Wire from USA
Stators wound and made in USA and Mexico
Assembled in San Diego
Designed in San Diego
Used around the World!



As you can see it we can be proud and say our motors are made on Planet Earth:)

Get the best what each country may offer, like a big tool drawer...

Mr. Neu,
Tnks for being honest with regard to materials and work to make your products. I think it clears up an misconceptions of neu motors.
As all can see it is almost impossible to make brushless motors today without involving countries from around the world, in order to make them in a price range the hobby can afford.
There should be room for competitors and medusa will find its place, I am sure of that.
