6s in a stampede
 

would a feigao 6s be to much for a pede? ive heard of pedes with hacker 8s doing 50mph rolling wheelies, and hitting over 60mph. it would only be run on 7 or 8 cells so i think it might be similar to an 8s. i currently have a novak 5800 and its incredibly fun and really quick, its just impossible to resist more power.

i doubt that it would be to much for a pede and it would certainly would be fun to drive.

What feigao6s are you talking about?

what other fiego 6s are there?

i was wondering the same thing

The Feigao 6s wouldn't be a very good motor for a 'Pede. It really isn't that great of a motor for any 1/10 vehicle. The Feigao 540 8s would be a better choice, or a Feigao 380C 6L would also work.

There is another 6 turn Feigao motor, the 380C 6t.

but it isnt called a 6s by other people is it?

Not by anyone I know. The Feigao 540 6s is the only one that I know that could be called the "6s".

Why not?

i dont think it would have enought torque thus it would heat up rather quick although im not sure.

Well, its kt (torque constant) is low, and to produce a good amount of torque it requires a LOT of amps. This means that you need good batteries, but even with good batteries runtime might become an issue. rtsbasic can fill in the details of this setup that I have left out, as he did run this motor for a while.
Basically, the 6s wouldn't be a good motor for a 'Pede, especially one with larger tires. The Feigao 380C 6L would provide plenty of torque and power, with a lower amp draw than the 6s, and still be pretty fast.

that makes a lot of sense now. thanks a lot. if i go with the 380c 6l what would be a good gearing? and how much slower would it be compared to an 8s?

You may need to experiment with gearing. If you bought a 6-pack of Robinson 48p pinion gears, you could try anything from 16t-26t or 15t-25t in even or odd increments. This is what I did, and I will have to figure out the gearing on my Rustler. If I had to take a guess, I would think stock gearing (18/87) should at least be a good starting point. One thing to keep in mind, though, is that the motor could get hot from being undergeared or overgeared, which is why I suggest a set of pinions that you can experiment with.

The380C 6L should be slightly faster than the 8s due to its higher kv. It may actually end up at the same speed since it is a smaller motor. But, it might feel like it accelerates faster, which is due to the smaller rotor.

so your sayin itll still wheelie the same as an 8s?

are you tryin the same motor in your rustler? let me know how it works. this motor might not happen for a couple months its still just a plan, and im still poor

The 380c 6l will wheelie better than the 8s because of the light rotor.

The 380c 6l will wheelie better than the 8s because of the light rotor.

No, I don't run low voltage. I only do 3s and 4s Lipo with my Rustler. I use a motor (Feigao 540 12s) that has a kv of 2958, so is perfect for 4s Lipo, and still works well on 3s Lipo (for racing).

would the mgm compro 80 amp 12 cell be a good controller for a 380 6l? it seems to be the cheapest that would work. it would be run on a 7cell ib3800 at first, but i think i might get a 3s lipo in the near future

it would work perfect. have you considered the mtroniks?

not sure what your talkin about. motor or controller?

nevermind found it. the 60 amp mtroniks controller says it can only handle up to 7 nicd/nimh cells but can somehow handle 4s li-pos which doesnt seem right. is there any reason why li-pos would require less from the controller?

The Mtroniks controllers can actually take up to 12 cells or 4s Lipo. The 75 amp Mtroniks (Mtroniks Pro) would be a better choice for the 380C 6L.

doesnt an emaxx with an 8l and 2s li-pos only pull about 45amps? how would a stampede pull more than that?

It's more for the insurance in it being able to handle a lot of amps during bursts. An 8L on 4s Lipo could burst over 100amps.

that makes sense. anybody know anywhere else to get mtroniks controllers. theyre all on back order at hobby people.

As MetalMan said, I ran a Feigao 6s for quite a while - infact I have two of them. Thing is, they're very good and powerful, if you have the right gearing for them, and you have very good batteries. As others have said it has to pull a lot of amps to generate its power, and this often brings the voltage of the battery that low that you'd get more power from a motor that can pull less amps. Having said this, when my 8 cell batteries were still matched and fairly new they gave my T2 and T3 great power with this motor (using a Mtroniks Pro controller), rolling wheelies at 20mph were easy, top speed was quite nice, 40-50mph depending on gearing and how much the tyres balooned. But my batteries have faded over the months, and I've credited one of my 6s motors with killing 2 of my batteries because the silly amount of amps it can pull.

At the end of the day if you plan on spending big money on your batteries as well, the 6s can be a sweet little motor, with the right gearing (too low and acceleration actually gets worse, too high and it'll overheat pretty quick and thermal your controller as well). But my personal recommendation would be a Feigao 380C-6L, these little motors pack a big punch, and that motor on 6-9 cells I reckon would actually be faster than a big heavy 6s. I have a 380-8t running in my RC10T right now with Masher 2000 tyres, and on just 6 cells it was pulling enough speed to clear tripples and quad's down my local BMX track. Don't underestimate them :)

Check your PM box..I don't really like linking to other shops on Mikes boards, but alas he doesn't stock Mtroniks.

thanks alot. it all makes sense now. im new to the world of brushless rc, except the novak ss but that doesnt really count, and everybody here is very knowledgable and helpful.
one last question though, what kind of connectors does the mtroniks genesis pro controller need, can you just solder the wires directly to the spikes on the controller? I cant find anything about it in the description.
also with this "return to bas" software upgrade do you have to ship it all the way back to the UK?

For the return to base function, you do have to return it to the United Kingdom yes. They have a very quick turnaround (and great customer support) - I'm in the UK so a typical turnaround time for me is 72hrs from me putting it in a post box to me getting it back and ready to go. Of course intl shipping takes a few days for you guys in the US.

I tend to just directly solder the motor leads to the posts on the controller, and use a Deans Ultra plug for the battery. You can't use the Tamiya compatible plugs you may still be using on a system of this power - they melt.

yea ive been using deans for awhile now, never melted a tamiya, but didnt particularly want to. shipping to the uk is more of a money issue than time, but oh well, nothin i can do about it. soldering directly to the controoler is simple enough, i wasnt sure because in the list of things that most customers bought with the controller it had 3.5 and 4mm connectors. thanks again for all the help.

No problem. The shipping cost is actually quite low - if you securely wrap it in some bouble wrap, you could send it to them in a $5 USPS global priority mail envolope. I use these for importing kit from the US all the time. They're pretty quick (average 5-6 days) as well. Just remeber to mark customs correctly or it'll get stuck there, a $20 value and "return for repair" as a description works nicely for me.

thats not as bad as i thought. how often do they have these updates, and how much of a difference do they make?

would a receiver pack be necessary running a 380c 6l and mtroniks genesis pro? also, i know smaller tires would be better than stock, but would it be better to go with maxx sized wheels and smaller tires, like mikes pede?

No RX pack is necessary with the Genesis Pro - that's one nice thing about it.

You can use small Maxx tires like the Panther Komodo tires (the ones that Mike uses).

Software updates come every few months..in the last 10 months its gone from V1.03 to V1.07B so not that regular..

Like MetalMan suggests, bigger wheels with small tyres would work well, as would stock sized tyres like Mashers. If you try maxx sized rims you do need to use RPM stablemaxx ones.

my brother use to use komodo tires on his emaxx. i might get the maxx size adapters and try those, but i think it makes more sense to just get smaller tires on 2.2 inch wheels.

i will post pics of my setup soon. i have the stampede-to-maxx wheel adapters, proline maxx offset dish wheels, panther komodos and s-maxx tires.

the maxx panther komodos are actually almost the same diameter as the 2.2 m2k's.

justin

i know their about the same diameter. all im wondering is if theres any reason other than ground clearance, why the heavier maxx wheels would be better than 2.2 stadium truck tires.

not sure how much heavier they really are.

i think it would equal out in the end because the 2.2 m2k's are heavier than the maxx size komodos.

my # 1 factor in going to maxx wheels tires is that the 2.2 pin tires are tiny - i would rather gear down than gear up.
