Help! I'm a Girl and Know Nothing About r/c!!
 

Ok, here's the deal. I have a revo chassis, and I'm going electric, more specifically , brushless. i have about $500 for the conversion, so the cheaper the better, but i want to be able to upgrade my motor to a Neu later on, apparently it and the mamba max don't play well :(
what do you recommend instead? might use the tekno conversion kit, because i don't want to use an emaxx tranny, and cut the chassis, all that stuff. Do they make bash-worthy li-po's now?

so so far what i need is
Feigao 540 9L
Tekno conversion kit
ECU of some sort
Battery and charger
that it?

Also one last thing, I keep hearing you guys talking about 'gearing' not sure what you mean, do you mean the spur gear, or inside the tranny? (sounds complicated)

the main thing i want is a e-revo that can keep up with the nitro's and have a long enough run time.

If you run the Tekno conversion then you really won't need to worry about the MM conflicting with the Neu, since the clutch system will allow the motor to spool and virtually eliminate all chances of cogging.

By bath worthy Lipo do you mean resistant to impact (like, physically durable) or do you mean those which have a long run time?

Personally I'd go for some FlightPower Lipo's. They seem a bit expensive but trust me they are well worth it...

BTW, welcome to the forums...

Welcome to the forums,

What are you planning to use your Revo for?
Bashing, Racing, Both?

If you want a cheap motor go with a feigao but if you want a very nicely built quality motor at a reasonable price go with a Mega motor ACn22/45/1. I'm sure Mike can get you one and they run smooth on the MM without having to use a nitro clutch.

I would also suggest looking at the NEU Energy cells for the most reasonable price/quality.

thanks for the welcome :) by bash worthy i mean something that won't break, long run time is a plus, from what i read it said li-po's are very delicate.

it would be both, but mostly for bashing really. maybe more racing later on, but by then i would have mroe money :P

The Lipo cells will always be vulnerable to punctures or impact damage unless they are encased in a hard material.

There are several manufactures that sell 2S lipo packs in plastic or carbon fiber cases. NEU energy even makes one.

I use a cheap solution from Radio Shack :lol:

The Radio Shack project enclosures work great for many Lipo packs, you just have to put some foam in them to protect the lipo's and possible add some venting by drilling a few holes but they are only $6 or less

Welcome to the forum

I would highly suggest the tekno kit as I really like mine and have had good success with it while bashing. Have put about 12 packs thru it and nothing has broken or loosened up! Well worth the money and i actually like the clutch idea, it should cure any startup cogging issues that some motor/esc combos have.

You can't go wrong with a mamba max, they are cheap and reliable. I have 7 at the moment and have oly had to send one in for service, and that was my fault! I would say get a feigao 8xl, rcm motor clamp/heatsink and run 4s lipo. The flightpower and neu energy lipos seem to be the best out there, and most have good success with truerc lipos. Hope this helps!

drilling a few holes is nothing :P i used to build robots for a high school team, they had cnc and everything, if they were up and running now i'd sell my own conversion kit :P

so which lipo's would work with the Feigao nicely?
and how much better is this 'mega motor' it looks a lot bigger, and is about twice the price..

The Mega motors are pricy, because of the casing design and they are a bit more effecient than the Feigao/ Nemesis motors and maybe higher in quality.

A good pack to go with is the MaxAmp lipo. It'll give you nice power and runtime. You can choose from a wide variety of lipo configurations( check it out in the store).

Any ways, if you want to go serious, the FlightPower and the Neu ones are very good and worth every penny.

Any 20c rated lipo will do the job, preferably 5000mah or higher.


The tekn kit does not require any holes, but you would need to convert over to a single servo for steering. You could also buy a RCM motor mount, and just buy the tekno battery tray and straps. I like the tekno esc mount as it gets the esc out of the way. With an 8xl you could lock the revo in second gear and then use the motor to brake and have reverse. Pulling open the tranny is not bad, just have an exploded diagram handy for reassembly. If you have built robots this should be a walk in the park!

The mega motors are much better than feigao.
The Acn22/45/1 is only around $175, is 6 Pole and would be a killer on 4S

You'd have to contact Mike to order it as I don't see it in the store.

What ever motor you get will only be as powerful as what your batts can provide so Flighpowers or neu energy lipo's will provide 20-30C (plenty of power for 4S)

could the rest of my revo handle that?
remember the $500 budget!! :P

by the sounds of it i can upgrade to that later?

one thing i don't like, is that even though the Canadian dollar is higher than the American dollar , the prices here have not changed, think i could work that out with mike?

I am all too aware of some guys out there, hah. Like I mentioned, I used to be part of a robotics club, I machined, built, and even designed most of it. However, when it came time to go to Atlanta for the world finals, i was left behind because it would cost too much money to bring me along (with the school board's rules i needed a female teacher to be present(no one would do it), my own section of the bus, my own hotel room, it was almost $2000 blah.) sucks to be the only girl sometimes :no:

I was hoping to go with a pink theme, it's been done though, boo!

Oh aye then, guess that means Im the next singleton in line. Welcome the.wert. Personally speaking I like the look of the Tekno battery and esc mounts etc, but coupled with the RCM motor mount so that you can still have motor braking & reverse. A feigao 8xl on 4s would be great, but you will need a ubec such as the CC item that Mike sells too. Locking the tranny into 2nd gear is easy- diagrams can be had in BrianG's sig (BL conversions- scroll down abit). There are a few hard cased lipos available as has been mentioned, but if the tekno battery tray is used, it is unlikely that you will managed to damage the lipos- newer cells are much less volatile these days. In the future you could easilt go to a neu 1515 1y for cooler running and more power, or perhaps sell of the current setup in favour of the MMM, which should only be about $300 for esc, ubec and motor! Cant say fairer than that really....

Guy's keep in mind she said $500 budget. Lipo's, ESC, UBEC, Motor, Batt trays, Deans, Charger, Pinion gear, ect... (ect being all the stuff I'm forgetting :)

Lipo's- Protek 2S 4000mah (two packs) $120 amainhobbies
ESC- Mamba Max $119 ebay
UBEC- Castle Creations $22 who ever hasd it in stock :)
Motor-Feigao (8 or 9xl) $80 here on RCM
Trays- Build your own, obveously capable$10 in alum. and hardware (the protek are hard packs)
Deans- $15 (get authentic ones)
Charger-Hyperion EOS0606i $135 with membership at MaxAmps (has integrated balancer)

$501 before any shipping, and then there's all the little stuff.

go with some deans off ebay (the ones that come from hong kong) they are like 15 bucks for 10 sets.

they work just as good as the deans you buy off towerhobbies

you could maybe go with 4s2p a123s. that would be a cheap battery (4s 4600 mah) for around 125.

they are extremely bash worthy

also lincpimp you are married arent you?

Quite right, add a rcm motor mount and a pinion and you are up another 80 bucks with shipping.

Not so sure about the deans knock offs. I had issues and went back to real deans and have had no problems since.

I've got a Feigao 9L motor if you're looking to buy one. I used it on my E-Maxx and it worked great. Since then, I had to sell my Maxx, so I don't have a use for the motor. You will need to get some connectors for it, or just solder directly to the ESC. The motor is in pretty good shape. It does have a little ding on the end bell from when I tried putting the motor system in my Rustler and doing a wheelie:surprised:.
I'd be happy to get $35 shipped (US) for it, if you're interested. I'll get some pictures of it too if you want it.

Brijar!!!:yipi:

I wouldn't advice the use of a 9L motor; they tend to run hot pretty easy; i understand you are on a budget, but the 9L is a hot running motor on 4S lipo's.

The mega motor is nice.

If you got the room for it, i would go 8/9XL and gear it up a bit more.

Don't know if you've seen the speed calculator BrianG made, it's in his signature and it works like a charm.

Here is the calculator:

Good info on gearing.

Welcome!

well the budget is flexible, if i could spend a bit more money now, and avoid doing it later, then i'm all for it, i work, so there's money coming in, i just wanted to keep it at around $500, how much better would $700 buy? :P

i don't have access to any machinery right now, otherwise i'd be milling away, making my own conversion kit.

I have to say the title is a bit misleading. You can hardly say you know nothing about rc. You seem to have done your reading. The only thing you have possibly overlooked is your budget. RC has a special way of blowing budgets to pieces. You should be able to get something up and running for very close to that budget but stopping the money flowing at that point is the hard bit.

Buy a Neu, Hacker, or one of the better motors... Batteries are perishables so you'll end up with different ones eventually. Better ESC's are an option too but I'm holding out for the Monster Mamba Max, so I wouldn't go high end there yet.

Revo's seem to always get the diffs replaced with better stuff from mike here at RCM.

Well, stepping up in either ESC or motor is a considerable jump. The next step for the ESC would be about 275, the motor around the same. It would be a better, more efficient (cooler) setup, but not sure if you'd want to hit the 1,000 price point... unless you become an addict like us. :smile: Besides, you're gonna want to save a few pennies to replace the oddball thing that will break...

I think the 8XL or 9XL, 4s lipo, and MM ESC is the way to go in your case.

i expect to spend more later on, for sure, this is just for the conversion, my revo is stock, think of the hop ups! However, I just want to gt it running at this point.

do you guys.. and girls... really stay within your budget... :lol:

I can never stay within my budget..... it always seems to double or triple... and quad sometimes... go with the high efficient setup... you won't regret it at all.... better to save a couple more hundred dollars and get something very nice... especially if you can afford it..

I don't know if you like pink or not, but check out this build: http://www.rc-monster.com/forum/showthread.php?t=8111

And here's mine:

http://www.rc-monster.com/forum/showthread.php?t=8850

i already read both threads, good stuff. A Pink E-Revo is the best one of gift a girl could ever receive, in my opinion :P

is there any once lace that will sell everything? i ask because i will probably get slammed by customs fees left and right.:tongue:

so one of the main things i want to do is get my revo ready for when monster jam comes to Toronto(where i live), they had r/c's on the track then, doing jumps and whatnot, before the show too. that's jan 19-20, gah!

so, again, i just want it to run, but i will just say the 'budget' is $800(give or take)
what would the set up be?

how hard would it be to sell the nitro guts? hmm.

You could buy PinkVo today and have it as soon as I get back home :tongue: But it uses an E-maxx tranny, stick packs, and a TQ3.

:bad:


Oh, and if you want a cheap setup:

TrueRC 4S LiPo
Hyperion or similar charger and balancer
Mamba Max ESC
Feigao 9XL
Tekno conversion or RCM parts (Tekno is easiest)
RCM 17 or 18T pinion (5mm)
Misc connectors, etc.

That about sums it up. I turned around all my nitro stuff in about a week or so. The engine took about 2 weeks though, since it's winter.

Are you signing up to run the Half time show at next years Monster Jam... Most of the guys there are running their Baja 5B and FG Marders... it's gonna be hard to hear the brushless over the Gasoline.... but I guess that's the beauty of it.... A bunch of guys from the London and TO area are gonna be in that show.... Any how, customs only charge you taxes, or $5-8 for handling... it's not bad.. as long as they don't ship UPS to you... USPS, Priority Mail or Fedex is fine....

Nitro guts are always easy to sell.... so you've just increased your budget to $1000. .congratulations...

I saw some baja's last year, i think, i havn't signed up yet, is room tight?

I'm not worried about it not being loud enough, with a hot pink body with Barbie Decals.. all the little girls will be cheering! it would get more than enough attention.

well.. now here's the advantage of being a girl.. contact the guy on offroadrc... I'm sure he'll make room for you...

As far as setups go, I would go with something like:

MM ESC
Castle BEC
RCM motor mount
Feigao 7 or 8XL
TrueRC 4S2P 8000mah pack
Tekno kit minus the motor mount
and the various odds and ends.

Personally, I would leave it 2 speed. That, with a Traxxas center diff kit and rear brakes would make for a killer setup. Thats what I'm gonna be running. I'm just waiting on my MM to get back from CC.

Yeah leave the 2 speed and mech brakes. It really works well like that. You may even be able to get away with a feigao 10l on 4s lipo and use the clutch provided with the tekno kit. I am running a similar sized aveox motor and it is fine, stays cool enough and can wheely on demand!

I take it you guys have tried the direct drive? For racing, it would take some tuning, but manual brakes would be the best. For bashing, I think the direct drive is best.

Actually my other 20 trucks are direct drive, no clutches. And they all use the esc for brakes too. I am trying some hv and 2 speed setups, so the clutch is handy and mech brakes are required. Just something different, but I will say that mech brakes help to keep everything cool!

Yes, I love the Mechanic Brakes... Direct drive and Mechanic brakes, would be perfect... Sike... you have picks of all ur trucks.. I wouldn't mind keeping them for archive...

Aqwut, here is a link to my photobucket album, feel free to look around and take any that you like! I will try to get pics of the rest of the trucks too. http://s206.photobucket.com/albums/bb243/lincpimp/
