neu vs mega?
 

well im not going to be getting a neu. the price is about 3 times too high for me... but this mega seems like something i could cough up the money for. its a 6pole 3500 kv motor. im not sure the wattage output or anything, but ive gotten the impression that megas are good motors. and this seems like something that would be prefect for my 3s revo project. would this motor compare to a neu motor? its more poles i think? which means it probly has a little more torque of the same kv rated neu? i know bluegroove used it in their conversion and he said that it was stock revo 3.3 speeds with unusable amounts of torque on a 16/38 gearing with the close ratio and two speed. sound like its worth the $150 to you guys?

Another question... Do the Mega motors use segmanted magnets? The answer to that will tell you alot about the motors and how they will compare to a Neu or Lehner.

all i know is that its neodymium. its a 6 pole three fase design... hers a link to the motor.

Here is the video of my little Mega ACn22/30/2 in my truggy:

Mega makes a good motor.

Megamotors does make a nice motor for the money. I'm using an Acn22/35 (3000kv) in my LS10 and it really flies. :yipi:

A fairly high slot to pole ratio is a formula for an efficient motor.
Segmented magnets are an expensive way to increase efficiency so I doubt Mega uses them as their motors are not over priced IMO.

That's a sweet looking truck what is it?

I think that is the early Mr Constructor MBX5T conversion...

I'm pretty sure the Mega uses segmemnted magnets. The cheap Hextronik – Quannum - HXT3670 uses them, but they are not wraped with Kevlar and one of the magnets on my Quannum already broke in half. I haven't seen a 4 pole+ motor have a 4 pole magnet like a 2 pole motor. I know the Aveox, Neu, Plettenberg, Mega and the Quannum are segmented.

Arct1k is right on the money. Mr. Contructor sure made a nice conversion kit, but it is expensive though at $450 euros.

If mega does use seg magnets then I'm going to get a couple soon :party::party::party:

I had the same motor in a heli, it worked pretty good.

i figured youd be in here lutach. that does seem like a crazy motor. thats on 4s right? do you think the 22/30/1 would do good in a revo with 3s? it seems like a good motor. your the one who got me interested in them, not i just want some extra followthrough from some other people. little mroe evidence of it you know?

I'm using 6S 2200mAh in the truck. The ACn22/30/1 will be nice with 3S. Keep in mind that the batteries are placed in front of my truck and the motor is smaller than a Feigao XL, but it is much more powerful. It pack so much power that it made the yoke (I think that is what it's called) come loose from the center shaft and I just got it glued yesterday.

oh thats on 6s? well i read that the 22/30/1 was basically stock 3.3 speeds(45ish) with almost unusable amounts of torqueon a 16/38 gearing with standard ratio and a 3s. i will probly run something like a 15/38 and a close ratio(mroe accel on the truck). guy said he had to tune the mamba max esc down to 50% punch. and what about the motor on a 6s? think that be insane? haha

I tried my truck with 4S as well when the MM update came out and it was fast too. The ACn22/30/1 will be really good with 3S and the MM with the new update liked the Mega :lol:. The amount of torque is nuts. In the video I made, you can see torque steer twice when I applied a full throttle.

seems to me like $150 for this motor is well worth it. so im looking at probly a ~$250 setup once i get the ESC and motor.whats with the noise though? that sounds different from other brushless motors ive run. its loud too. does that truck have a center diff? didnt look like it but it might have been there. if not then will it not lift up just cause of length and it sits low? can you see it doing wheelies easily without a center diff in a MT? geared for about 45mph?

That truck was in a bad crash. I lost signal and it went straight into a curb. The pinion and spur is not that well aligned and I had to play with it a bit to have them run somewhat smooth. The conversion kit came with a slipper, but I took it out because the spur gear had melted. The spur gear for the Savage is working good so far and it is not a solid center kind of like the one in my BPP truck. When I had the center diffs in my buggy and truck it would still do wheelies, but the unloading to the front wheels afterwards was really messing the tires very fast. Mega makes a strong motor. The magnets are strong like the Neu motors, but the Megas have 6 poles and will draw less AMPs. Keep in mind that electric motors have the uniqueness of getting power from torque.

Yes i know. so the 20/30/1 at 3500 kv on a 3s lipo will give me roughly 38000 rpms(stockish speeds) and has the torque of brushless so it will be a gearbox/tire killer(which is fine because they all need replacing anyways). wheelies on demand with the motor? no where close to the amp draw that the esc and battery put out. so everythign will run cool. sounds liek a hell of a motor to me.

My Schulze controller never felt better. I was also impressed on how the MM handled the motor after the update.

what update?

The new firmware for the MM version 1.17.

I didn't really notice a difference with my mega and MM after the FW update, it was smooth before and after.

I also don't really notice any difference in noise but my car is using a steel spur and pinion so that's mostly all I hear :whistle:

Before the update, my MM used to cog and sounded kind of like a grinder. Sometimes it would go forward and backwards. It would also tend to heat up. After the update it did much better.

ok either way the new one will most likely come with it. and both of yall say good motor for a heavy truck on 3s? possibly 4s one day?

I think 3S lipos will be good for the ACn22/30/1.

alright i think ill order it within the next week or so then.

I am looking to put the 2500 Kv version of that Mega motor in an Ofna GTP on 6S A123 cells. I am looking to gear it for 60 - 70 mph. Nothing faster than that. Well that and bullet acceleration.

you could probly run something slightly higher in KV and still get rocket accelereation. considering its a 6 pole(naturally more torque) and if lutach isnt lieing about how amazing the motor is im sure it will give you everythign you want.

If they say a picture is worth 1000 words, how about a video :lol:. If I had my choice of motors here they are: Neu (First because they are here in the US and RC-Monster sells them), Plettenberg (Icare-rc sells them), Mega (They have an office in the US, but still needs 6-8 weeks to get special winds in), Lehner (They would be in first if RC-Monster still carried them). I might add another one later if they get made or if I get a sample to try out.

lutach are you sure they are not kevlar wrapped on mega usa site I believe they say they are

a video... worth way more than a 1000.

you say all the things like first because they are here in the US and rc-monster sells them and places sell them and stuff. if you were rating just the motor alone. no factors of where they are made or anything. just the motor. what would you rank them?

Yes, they are Kevlar wrapped. Here is what they say it can handle in terms of RPMs, "(e.g. all actual types of AC electric motors MEGA, which have a bandage of kevlar material, can hold 75 000 rpm but also 145 000 rpm without damage!!!)".

I'm pretty sure I said they were Kevlar wrapped somewhere.

75000 RPMs?! from what i read they say only up to 44000 RPMs...

I have the ACn22/30/2 and for the size it packs twice the torque of my Feigao 7XL. I would rate it even with Neu (Aveox if they would return to the game) and Plettenberg just because they are all 4 poles and 6 poles or more (Some Plettenbergs are 10 poles).

so the mega is a neu in performance even though it has such a small size? because if your now saying i can get a neu for around $200 and it will outperform the mega then i would pay the extra $50 for mroe performance now that im spending all this money anyways

Just wait to see what people will say about the MMM combo when it comes out. I know the Mega will have more torque due to the 6 poles. I know it has it because the little 22/30/2 is an explosive little guy. I can't inmagine how the 22/35, the 22/45 and the 22/50 will be. I know you can get a 22/50/1 which will give you around 2400Kv and the motor looks awesome.

wait a 22/50/1 with 2400 kv... god i bet that thing would have stupid amounts of power... you could probly gear the crap out of it too...hmm if its not much mroe expensive than the 22/30 then i might get something up in the 22/45 or 22/50 range. and i was thinking of waiting for the MMM, but its supposed to only be a 2200kv motor, which on 3s would have no where close to the speeds i want/need... plus if i can get soemthing with compareable performance(mega and mamba max esc) for less than $250 then im going to do that

The ACn22/50/1 is $299. The 22/30/1 and the 22/35/1 will be your best bet for 3S. The 22/45/1 and 22/50/1 will be good for 6S. I'm not sure if you will be only spending $250 on a Mega/MM combo. Just wait for the MMM. Plus if it comes out in March, some guys are saying Castle has a 25% discount.

yeh i can wait around and gear it really high and run a smaller motor i guess. problem i see with the MMM is that the motor is only for 2200 kv... even if it makes something crazy like 2000 continuous watts(2.6hp) you still probly wouldnt be able to gear it low enough to run at the speeds im looking for...
