Kontronik FUN motor
 

Is somebody know this motor??? I've toast my feigao 10L today in my slash, and the only motor i can have before the next week-end is the Kontronik FUN 500-27. It's a 50mm can, 2700Kv.

It's $150.00 CAD

Wait for your comments!

Thank you

Ive heard from many people that they dont have many advantages over simple feigaos of the same specs and are definately not worth their price.

OK finaly a friend of me (E-Mike, the MMM boyz:lol:) have ship me his feigao 9L back up motor!
But now i have to order a new one because i don't expect this 9L to have a very long life.

I don't want to spend over $150.00 on a motor. For sure, a Neu 1512 is my dream, but it's too much money.
What do you think of Medusa 60mm motor?? They don't have a very great choice of Kv, but the 2000Kv will be not to bad for me.

The medusa 60's are suppose to be great. Their was a review of a neu 1512 or a 1515 up against a Medusa 60 series motor and the guy prefered the medusa over the neu. Kind of ironic but if their that close in performance than I wouldnt bother spending the extra money.

Well, but the problem is that the Medusa 60mm don't have Kv over 2000Kv.
I would like to try a 3300Kv.
I just don't know if it's better to have a high Kv motor with a lower gearing, or a slower Kv motor with a higher gearing.:neutral:

My Feigao 10L, on 11.1 volts, geared 17/54 (32 pitch) had good on power and ran cool, but i would like to know if a higer Kv with a 12 or 13 pinion will be better:neutral:

I would have thought a Medusa 50mm 3300 would be fine... I run one in a CRT ,5 and have had no issues...

I've think about the medusa 50mm, 3300Kv, but i think that it'll be little slow for a Slash. I'll prefered a 60mm

It is a little torque monster - Mike uses the 60 2000kv in his e-Revo which is much bigger than the slash...

OK guys, thank you for all your input, but i just order a Neu 1512, 1.5d/s on Impakt RC.:lol:

Funny!

:rofl:.......................................... Not really, but a good purchase indeed. :yes:

Not to get too far off-topic, but I too want to get a MedUsa motor for my CRT.5 and Slash, but want to use a 3300kv motor for 3s use. Noticing that the 60mm version (which is really the one I wanted) doesn't come with the right kv, that leaves the 50mm series. But, the current CC4600 motor in the CRT.5 gets too hot for me, and they are 50mm long just like the Medusas. Granted, there is more area for the coils in the Medusa since the CC motors have to leave room for the coil wire to noodle wire junction inside the motor. What are your temps/gearing/tire size for the CRT.5?

Not sure about everyone else, but are you running 3s with the 4600 Brian? I've heard from magman that the 4800 medusa on 2s runs powerful and cool, too.

No, 2s right now. I know simply going to 3s on a lower kv will be worlds better, but running 3s on the 4600 would make it too fast. I'm already at 46/12T on the gearing with 2.2" tires.

I'll try to get some runs in at the weekend but have not had an issue with temps at all - I have it geared 18/46 on 2.8 for 2s at the moment - But also run 16/46 on 3s...

I need to hook up with Lutach for some speed runs on 18/46 4s...

With the Neu 1512, 3200Kv, in my slash, i'll use a 58T Jato spur with a 13T pinion, with proline badlands tire (4.8"), and i'll have (theorically:lol:) the same speed that i had with my feigao 10L, geared 54T/17T.
But i'am sure that the efficiency and heat will be different.

Another question, maybe for BrianG or other guys here, what does mean the Max Amps in the motor description. For exemple, for the Neu 1512, 1.5d, it's 135A.
For a 1512, 2.5d, it's 78A.
For a Feigao 10L, it's 61A.

I think that's the max current that the motor can support, but not sure.


Thank you!

Usually, each motor series has a rated max power value. Motors also have a max rpm. Then, each wind has a different kv value.

So, let's say a motor is rated for 1,000w, max rpm of 50,000, and a kv of 2000:
Voltage to get max rpm = maxrpm/kv = 50,000/2,000 = 25v
Current (using ohms law) = power / voltage = 1,000/25 = 40A.

On a 1512/2.5d (60k max rpm, 2050kv, 2000w surge power): Max v = 29.26v. Max A = 67.6A. But, they probably round down the voltage to a common lipo value, so the voltage becomes 7s (25.9). Max A then becomes 77.2A, which is pretty darn close to their spec'd 78A.

That's the only way I can think of that they come up with their numbers...

Without plugging the number into Artur's motor program a quick guess would be that those listed currents represent peak efficiency, where exceeding that number results in rapidly-decreasing efficiency ratings. Yay/nay?

No idea - could very well be so. But without the program, it's hard to verify that that's what they are doing...

OK BrianG, so let me know something. I've order a 1512 1.5d, 3200Kv, with a Max curent of 135A. I'll use it on 11.1volts. If i consider a gearing of about 40m/h, is this motor will pull more amps from my li-po than if i would have take a 1509, 2d, 3300Kv, 95A, for a same gearing:neutral::neutral:

And what about heat and efficiancy???

Just order another one, a 1509 2.5d, 2700Kv:lol:

:gasp:Too bad, just see that i can't put a Neu motor in the stock slash tranny, Neu motor have a diameter of 40mm (smooth can) and Feigao have 36mm:surprised:
The only way to put a Neu is to order the RCM FLM alloy tranny case...........................And that's what i just did:eyes:

The only problem is that the rear bumper will not fit anymore:neutral:

No. The FINNED can neu is 40mm. You'll be fine with the smooth can at 36mm.

No.... the SMOOTH can Neu is 40mm. The finned can is even bigger. Feigao and Lehner are 36mm.

:oops:

Yep:eyes: that's what i've see on the Neu website

i thought fastlane had a case that would work with the bumper?

No i'll have to make my own mod to fit bumper.
Bah!!! anyways, no need rear bumper after all, i'll just have a Neu 1512, 1.5d on 3s, don't think that my slash will wheely:lol::lol::lol:
