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:

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.

Revracer 01.30.2008 07:10 PM

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.

Revracer 01.30.2008 08:10 PM

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.
