how would you keep dirt out of the motor? its got the huge openings in it and i'd be worried bout dirt and rocks and debre flying up into it... do you have a video of any trucks with the motor. or a similar one

MGM's 80A controller or the Quark 65A controller.

I didn't do anything to cover the motor so it was open. I ran the truck on asphalt and didn't make a video. I was by myself at the time and I just wanted to run the motor. You might be able to use a fine screen, cut hole for the screws to go through and zip tie it to the motor.

that could work. and both of those ESCs, they need an external BEC right? are they as strong and programable as the Mamba max? i know the mamba is rated for like 100A i think?

You can use a external BEC or a receiver pack just remember to remove the red wire from the controller. The MGM is somewhat confusing to program as some folks in the forum pointed out. The Quark is as programmable as the MM with out the PC capability. Keep in mind that in my opinion Castle over rates their controllers.

Castle might, but nothing but positive feedback is the reason i was planning on getting one. where could i find a video of a truck with the mega other than on their site? i want to find one in a MT on 3 or 4s. and i might just get the 7xl since it is something i know will work amazingly. i would like to get other peoples feedback on this?

Why on earth would you say that?? The MM is only rated for 4S, yet the older ones can handle up to 5S. Even Castle reps said its good to go on 4S with the right setup, but it was just rated at 3S to cover there asses.

well im getting the mamba. i looked at both others, but just the feedback on the mamba sells it for me. but motor. 7xl or mega???? i cant tell which is better.

I got that from a few posts in rcgroups. Now I'm saying that from expirience as well as the Mamba seems to overheat easely. I have the new controller with the same set up that I had with the MM and it doesn't even break a sweet. Castle will be like Novak one day.

is the mega motor worth the extra $50 or so? i mean a feigao will be about $100-110 after the heat slink clamp. but is the mega worth the extra? is it that much stronger?

I'm dropping a 7XL and MM w/ the Castle BEC in my eRevo.. using 2 2s2p 6000mah lipo's to power it. Actually just waiting for my 5mm pinions to arrive by Friday with any luck.

what about on a 3s 5000 lipo though? what are your opinions squee? you think the feigao or mega?

I have no experience with the Mega, and haven't heard to much about them, but from what Lutach has said, it sounds pretty good. I might try one myself.

If they were bad, Mike would never sell them. Feigao is has good price, but one can never compare a Feigao to a Aveox, Mega, Neu, Lehner, Plettenberg and a couple of other good brands out there. I have most of the brushless goodies you can have and I played around testing what works best. I like my MGM 8012 and I have it in my TC3 Truggy. I had the MM in there, but the MM cogged really bad with the HV4.5 motor. As soon as I had the MGM 80 programmed it ran ultra smooth and cool. I said before that Castle over rates its controller basically because the MGM has a rating of 80A and runs cooler then the MM. I like the MM, but I haven't used it for a while now. If you do get the 7XL make sure you get great lipos and I would recommend GriffinRU's mod and a nice fan. Just my opinion.

im running maxamps stuff. thats what i like and trust the guys there. im sure mega is good, but im not sure if it will be worth the $154 price tag. and i would have liked to get mroe feedback on them... i mean 3500Kv and more torque than the 7xl sounds amazing to me. but... all ive heard is what lutach has said. ive heard tons and tons of great stuff about the feigao...

Just me two cents:

Feigao motors are a graet deal, comparing their performance to what they cost. For the average basher a properly setup MM and feigao will offer exactly what they want. The money saved can be used to buy better batteries (enerland cell based), which I highly suggest.

After some amount of time a feiago user will want to step up to a better motor. I am sure that the mega motor is more effecient and cooler running than a feigao. Plus it is most likely more powerful. I noticed the same thing when going to hacker motors, supposedly feigao are hacker clones. That is like comparing apples to oranges IMO. If you budget will allow for a better motor, buy it. If not go for the feigao motor, they work just fine.

I find the humor of your statement lutach. Saying that the mm gets hot due to the fact it is overrated is incorrect. The mgm has superior programming, in that it does not seem to mind what type of motor it runs. Same with the quark, save for a poor heatsink design. The mm is an excellent 2 pole motor contoller, and an amazing value. No doubt that the higher priced and rated escs will work better, however there is no need to buy a 300 esc to run a 2 pole motor on 4s, the mm works just fine for that. I have run mine on a 4 pole plett and had good results, but it is in a smaller/lighter vehicle.

so for mostly bashing and very light racing(small club racing where no one is competitive and the fastest motor out there is probly a 3.3) the feigao with a rc-monster clamp will be my best bet? looking for 35-40mph speeds and enough torque to do wheelies.

Explain something to me. I ran the MGM 8012 which has no heatsink with the same set up I ran the MM and the MM thermaled a few times and the MGM didn't. Yes, it might be better software coming out of the MGM, but it has a rating that is 20A less then the MM and no heatsink. If someone is on a budget, then yes go with the Feigao and MM. I just wanted to help out in pointing a good efficient sytem.

well i wish i could afford the extra $50 for the motor and all. but im barely able to pull through with the feigao, clamp heat sink, and mamba max. and a mamba max is rated for higher amps draw. more amps pushing through it means hotter temperatures.

Well, what kinfd of amp draw do you think your setup was pulling. I know that the mm is designed to spin a 2 pole motor, maybe that is what its rating refers to. Using a higher pole count motor seems to load the esc more, and may lower its ratings to suit. I feel it has alot to do with the programming. Quark and mgm got it right, for many different motors, while cc may have only tested their 2 pole motors (feigao-style) with it. I am sure that the meg/mgm setup would be alot better than the mm/feigao setup. But it is also nearly twice the price, which is revracers issue at the moment. I think it is good to start with a cheaper system to get used to brushless, and then graduate to a better system. That way if you destroy something due to assembly error it is cheaper. I still run feigao motors, but have gone to lower kv motors on more voltage, which the cheap motors seem to be more tolerant of. I guess that the lower amp draw thru the motor masks the ineffeceintcy of the feigao.

well i know about brushless. i run an lrp system in a TC. a mamba max 4600 in a DF-03, and a vxl system in a rustler. and for a while it was in a maxx. so if i go with the 7xl ill have decent speeds and enough torque to lift the tires off the ground on 3s. and once i can step up to 4s it will be insane? more in the 40-50 range than the 35-40 range?

I can say that a 7xl on 4s is a fast setup. I gear all of my vehicles for around 40 so It all depends on motor speed. Keep the motor speed below 40k rpms and it will run well. Any more than that and the feigaos start making alot more heat.

what about on 3s? and what kind of acceleration will i see? gearing? i would like to go ahead and get different clutch and spurs if i need to. order it all at once.

That is cool. A lot of people have great success with that set up.

You really can't beat the price of a Feigao. You can have a Feigao and a RC-M heatsink/clamp for half the price of a Mega.

This is true. I love the look and everything I've read about the mega, but I have an 8xl and am very happy with it. It's strong, fast, and tough. ESC's however, I have much less luck with. I've been through 2 quarks, 1 mgm, and one MM, all fairly recently. :|

The MM is a fine controller, but it's prone to blowing caps. Adding a few caps doesn't hurt, and running a BEC or RX pack will help keep the temps down. Keep a close eye on the temps. They don't thermal soon enough, so you can do some good damage from heat before it turns itself off.

It would be nice if Castle let you adjust when it shuts off via the CastleLink.

alright well i have a temp gun so temps wont be a problem. im makin my order this weekend. im going with the feigao 7xl, mamba max, and tekno kit. and you sure this is gonna rip on a 3s? i mean i know it wont be fast. but 35mph and getting there in a wheelie to me is ripping. atleast in an mt. cant do much with MTs at 45+mph so 35 is fine with me. and wheelies has to be there:whistle: haha. still no one knows if it will lift off the ground?

It should.

should isnt a word i like to hear when im about to drop $400 into a truck.... if it does with how i gear it(18/36 probly) than i will just drop a few teeth and a little bit of speed. thanks for all this guys. lookin forward to a nitro killer

Well should is as good as it gets from me. I'm not gonna say it will, when I don't know for sure. Like I said, I have a center diff in mine, which prevents wheelies. I'd rather not say it will and then it won't. Besides, 18/36 will probably fry something instantly. Try 14-16. Mine MM gets rather warm on 16/36 with the internal BEC in use. Everything else is stone cold. I was gonna order a 14 and 15, but there out of stock...

well i will probly be using an external BEC, even though im only on 3s for now. also will have a fan running which will help. but hey if it doesnt wheelie. if anything it will launch harder than nitro right? because even if it wont lift up, if it will outdo a stock revo or t-maxx from 0-30 than its fast.

I've seen a coupld videos of Rvos doing what you want with the L motors. So the XL will do it.

Also take into account my ESC settings. I set my throttle curve so that it doesn't start accelerating until about 1/2-2/3 throttle.

which slows the power curve.... so on stock linear power band it should be plenty of acceleration. thats good. thanks guys

Since you will be keeping the 2 speed and mech brakes and 3s lipo, may I suggest a feigao 8l. It will allow decent speed, 35mph plus, with normal gearing. 40/16 gearing will be fine and will most likely run cooler than the 7xl. The 8l with 3s will turn faster than the 7xl, and the mm will most likely see a lower amp draw with the 8l. Because you would have to gear the 7xl higher you place more load on it, causing a higher amp draw. I have personal experience with the 8l on 3s lipo in a revo, and it ran fine with good temps. plus it is 10 bucks cheaper. It will also be wise to run a ubec, it will help the mm temps.

i was going to run a ubec. but will the 8l be as quick as the 7xl? i mean will it have the same acceleration and everything as the 7xl? and a 16/40 is way different from stock. stock is 18/38. but wit ha 16/40 it will still do around 35? will it be able to handle 4s once i step up to that?

You will not find a motor that will work well on 3s and 4s. You want the motor speed of a feigao to be around 35k rpm. Much more and it will get too hot. Much less and your gearing will be too high and the motor will heat up due to increaded load. The 8l will easily pull wheelies, and we geared it for 40 mph and it ran fine, just a little warmer than the 40/16 gearing. On 4s the 7xl will be a beast, but 3s will not spin the motor fast enough.

well i plan on using a 4s later on. 3s for right now. and later on down the road it will be 4s and 3s. so easy wheelies and close to 40mph with the 8l on 3s. and on 4s its useless? so i wont need to drop the money into twim 2s packs. and it will still be a nitro killer... hmm... i kept hearing that a 7xl will be good on 3s though. i know tekno used a neu rated for 2500 kv and a 3s with the mamba and in the videos it looks like amazing track speeds. good combo of torque and speed. and on 4s it will be an awsome basher. if an 8l will have as much or more acceleration and slightly higher speeds on 3s, it will be good. but id like to be able to run the crazy voltage and have a serious basher

Well for 60 bucks it is cheaper to buy another feigao than a 4s pack. Try the 8l out, you can always sell it. They usually fetch 40 buck or more used.
