Which is better? (mega/feigao)
 

I'm looking at the mega ACn 22/30/1 and the feigao 380c-6L. Which is better? Whats the differences between the two besides price. This is going into a ruslter with 3S lipo. Thanks.

The Mega.

- better quality components.
- hand wound and better quality control.
- 6 pole vs 2 poles.
- more efficient.

here's some more info:

the megas are better quality motors... you really can't compare the two..

OK thanks for the input. The megas are 6 pole which I'm not sure if that work with my speed control but I guess it's worth a go. If it doesn't work I can get a different speed control.

Which ESC do you have? If it's any of the BK-Warriors, you're right, it won't work. Other ESCs should be ok though.

I have the stock traxxas vxl one. I just ordered the mega motor so I'll just have to wait and see.

Well my mega motor came in today. I put it on and its not working right. Just holding it in my hand the motor kicks hard and no cogging what so ever but it seems to not be getting max rpm. Holding the motor in my hand the rpms climb fast but it seems to be lose power then power comes back really fast back and forth. The motor barely gets warm and the speed control, bat and wires are all cool. Any suggestions? If its the speed control what one would you guys recommend?

Quark 80b maybe? I think they are better suited to multi-pole motors than most escs, although the Mambamax should be fine too probably.

I called mega and he said my controler probably has a built in rpm limit and with the 6pole design the controler thinks the motor is spinning at a much higher rpm then it really is. He also said that the mamba max would work fine. Should I go with MM or wait for the MMM. I only plan to run 3S but I like the fact that the MMM has a built in fan although I might be able to rig my fan up to work. descions decsions.

speed demon, I would imagine you could pick up a MM for a real low price once the MMM's hit the shelves. If you arn't going past 4S soon I would wait a few more weeks and start watching ebay and the FS threads for the MM's people will be offing cheap to help fund their MMM purchases.

The newer software for the MM makes running multipole/outrunners smooth as silk.

Will I need a fan on the MM I just sold the motor, heat sink, controller and fan to a friend. What fan do you recomend for the MM. Thanks for all the help guys.

You could've asked some other people or even myself as I tired the VXL and I think I even posted something in the forum about it not working with the Mega. You had a very nice motor and it would've made a nice motor for the MM, Jeti Master Car maybe even the Tekin R1. You just threw away a great high torque motor. Maybe you sold it for more then you paid for them.

:surprised:Ditto what lutach said, you should have kept it. I hope you got good money for it.

I got a ton of runs on the motor and truck all together. Was looking for abit more power and efficiency. I did get alot more the what I thought I'd get out of it. More then enough to buy a new speed control and a fan outright. There are 5 of us that race and 4 of us that have rustlers. 2 with vxl the other two regular with modified motors. We try to keep everyone even so its fun. I run my rustler on training mode to keep everything close. Well they found great deals on 8 cell nimh and now are walking me on training mode but I still smoke them on 100%. I figured maybe a better motor would even things out.(still very new to this stuff) But since it won't work and one of the guys wanted my setup I just sold it to him and now I'll buy the new MM and fan. Didn't mean to offend anyone.

No one is offended, some of the guys here are just motor guru's and can tell you what motors are good-ok-not bad-cheap- or junk hahaha

Besides budget is everything, and no one would knock you for selling it off to step up to a Neu -wink wink-

OK I'm alittle lost. I sold my vxl motor and setup not the new mega motor. So I screwed up becuse the mega motor I got 22/30/1 is not as good as the vxl motor? What is the differences?

HAAHAHAHA ok, I think we all thought you sold the mega :)

vxl is not as good as the mega.

OK my bad. I was starting to sweat over here. Thought I made another mistake.

On the MM is the new software already programmed or do I need to download it from some where? Also I noticed the mega has openings at the front..could a use a snap on heat sink to cover these up so dirt and stuff doesn't get in? Or is it open for air flow to keep everything cool?

If you run in any kind of a dirty/dusty area, you may want to seal those hols off IF you don't have any heat issues.

The MM should come with the programming cable (USB) and a disc to install it, then it will automatically check for updates. I think the current one is v1.19 and it should tell you what the version is when you plug it in to adjust settings.

Temps should not be much of a problem at all if you are still running NIMH, but if that's the case you may want to look into lipo's. Way more power!!!

There are a few debates as to what lipo's work well on the budget end, the zippy's are cheap and people like them so far. MaxAmps have the most complaints for their price, and Neu Energy (sold here in the RCM store) are a sure bet.

(going back to re-read your setup now :)

What IS your setup?

LOL setup as in?........OK just a rustler with an hot racing trans case. One milehighrc 3S lipo 4000mah, a Imax b5 charger with a custom power source. What other info do you need? Oh gearing is a 26pin 76 spur. My temps on motor stay at 115 on a cool day but lately have got to 187 on the hot asphalt racing. I do have a 23 will probably buy more just to have.

Asphalt racing gets the temps on the high side, lots of traction next to dirt. gearing may have been a bit too high for the VXL but may be much happier with the high torque of the mega/MM combo.

Glad to see you have the lipo (I've got the B6 and love it). Youve got a better tranny case so I think the gears may stick around for a while.

Seems like you are right on track to me, but yah, you shold keep a good range of gears on hand to tune for temps later. How are the temps of your lipo when racing?

It has only broke 100 twice that I know of. I built an aluminum plate at work to raise up the speed control so the bat could fit under. But the plate seems to draw heat out of the speed control and makes the back of the battery warmer then the rest but only by about 10 degrees.

Also I only race on training mode so I don't think I'm pulling that many amps. Even on speed runs my battery doesn't get hot but my motor and speed control seems to cool down. Still trying to figure that one out.

You should be pleasently supprised at the difference the mega will make. You'll also come to love the MM programability. Sorry you have a bit of a wait till the used MM's start popping up all over the place. The wait to purchase it should pay off well $$$. You may even want to pick up the MMM (if cash is a non issue), it's a bit bigger than the MM but if you've already built a better ESC mount you may not have fit issues. Later on you could go to a higher voltage (~6S lipo) if you wanted...

Other thing is if you are using 3S you should also be using a UBEC, it will keep the ESC cooler too.

Edit: the MMM will have an internal UBEC

Whats a ubec? I probably will order a MM tonight or tomorrow. Time is kinda an issue right now since my racing days are close to an end. I race with guys from work 4 times a day and the place is closing and I'll be moving. I will still use it as a basher but as for racing other guys who knows.

UBEC is a switching voltage regulator, it takes the 11.1v the lipo puts out and makes it the 5~6v the radio/servo's need.

The ESC usually has a voltage regulator in it but it workis differently, it's a linear (not switching) regulator, so it has to bleed off some heat (wattage) to bring the voltage down to what it needs. A switching regulator turns on and off at a controlled rate to produce the proper voltage without much heat at all.

The bec in the ESC will get hotter the more volts it has to bleed off (heat you don't want in your ESC) using s UBEC like this http://www.castlecreations.com/products/cc_bec.html will remove heat from the ESC.

Have no fear about getting the MM, lots of guys have run them in some heavy hitting MT's with good success, you'd be one of the few actually using it within specs hahaha. No worries.

OK thanks doc for all the help much appreciated.

No problem, I love it here because of all the help I get :)

I probably came on the wrong way. My apologies. This are the top motors so far that I have come to know: Neu, Mega, Plettenberg, Hacker and Lehner. They are top notch and a lot of times copied by others. I have a little ACn22/30/2 that is just balistic in my MBX5T. Runs cool and has more power then a Feigao 7XL. From what you've told us, you got a good del for it and that's good.

I swear you said you sold the Mega motor. That is one good motor and you can make great things happen with it :lol:.

That's what I thought too. As I understood it he was keeping the VXL motor to run on an MM. Good to see that isn't the case. In my mind is was like trading a lexus in for a cavalier.

:lol:. For me it would be like trading a Jaguar for a Pinto :rofl:. Just joking. Good thing he is keeping it.

Awww, come on! The VXL can't be THAT bad! Maybe more like trading in a Lexus for a Toyota. All the Cavaliers ('98-'01 era) I've worked on at the stereo shop were absolute crap! If a Lexus is a Mega motor, then a proper comparison to a Cavalier would be a TP tube (empty).

ROFL. BrianG, you always seem to find a way to crack me up! :rofl:

Sorry guys, I will work harder on making better comparisons next time.

lol, not like linc, but I try...

Linc is in a class all his own, and it scares me sometimes!

Glad a made the right choice. I just order the MM and a few other odds and ends this morning so it should be here within the week. As for the cars thing I drive my 72 Dodge Demon and for me there is nothing that comes close........except when I'm at the gas station.

Demon, getting hard to find. Good choise for a ride, guessing it's 318 v-8? Or are you one of the few with the 360? The new (old style) hemi's have not dropped in price since I was 16 and I'm 32 now, still ~$8,800 complete...

I ran a 67' chevelle SS 396 (changed it out for a 454 that was making 580hp and 616ft lbs torque) I had it running 10:80@138mph in the quarter. That was when they wanter fire supression, 5 point cage, racing hrness, ect. Couldn't afford the gear so I quit racing. Wish I would have kept the car, but I really wanted a 64 chevelle anyway.

10.80's holy crap that's fast. Mine is a daily driver so its not that fast. My best is 12.507@112.5 with sickening 2.1 60ft.(street tires) I have the power to get into the 11's but don't want to try slicks just yet. It was an original /6 car but I built a 340 with race aliumiun heads that I ported and flowed.(287cfm@ a low .525) Ross pistons manley rods forged crank ect.... I constantly swap pigs from 4.10 for racing to 2.76 so I can drive it without spinning the motor to the moon on the interstate.
