Batteries, Motors and ESC

Post by OrangeBrooke » Tue Jan 06, 2015 5:16 pm

Hi All Gene here. I have a Custom Clod that I build years ago. The truck was built up as a Bulky 1/6 scale Monster Truck. I am on a budget of about $300, So if I can get a complete setup of motors, Pinons, ESC and batteries that would be awesome!

What I'm wanting to know is!

1. What are some of the best motors too have for crawling (Can be Brushed or not)
2. Low Pinon Gears (Looking for low and slow high end pulling more or less, If I said that right, lol)
3. A good duel-esc (Must be a duel motor esc)
4. Long Running Battery (I'm looking for a 2 battery setup for a run time of more than 20-30mins a run! Not sure which battery would be best, I was thinking one of these but I donno! http://www.nitrorcx.com/gens.html
5. Getting off my hump and going outside in the -2% and run my truck, HAHA :P

The setup I have now:
2-Old Titan Motors w/ 16t pinons
EVX-2 esc
2-regular 7.4v batteries in series

The setup I have now runs good for Speed runs only!
I won the lottery in my dreams, Go figure!

Do you use lipo? Will that esc power up from 7.2v? If not you can do the same setup but with 3s lipo instead of 2s.

Use the same ESC on stock pinions with 45-65t Motors. Holmes hobbies are the best as far as brushed goes.

Run the batteries in parallel for maximum run time. With 2 4000mah batteries in my trail truck I would drive for 4 hours in sub zero temps and never ran out of juice. I'm sure the truck could have gone for 5-6 hours. So a big heavy monster clod should get 3-4 hours I would think.

What does 2s and 3s mean?

Not sure about Lipos, I run the old style Nimh type batteries atm.

2S - 2 cell lipo (7.2v)
3S - 3 cell lipo (11.1v)


The batteries you linked to are all lipo, as for Gens Ace, a lot of people use them without issue. I have only had one set and the connections were crap making the batteries useless with in the first month I had them.

Hobbyking batteries are pretty good though.

If you go lipo its a good idea to have a low voltage cutoff in the ESC, however, i've never actually hit my low voltage cutoff. The batteries die to the point they can hardly move the truck before it ever comes on.

I cant comment on running NIMH packs in parallel because I have never done it.

Ok, So I have an idea of what batteries to get down the road., I have a Transmitter in mind also.

The Esc I have in the truck right now is the https://traxxas.com/products/parts/escs/3019Revx2lvd

I wouldn't mind getting another one. I can get them off e-bay no problem there. Would you know of another duel-esc that does the same job but cheaper?

I do want too get smaller pinion gears as well. What would you recommend? 6t 9t? I'm not good with gears and whatnot. I would like the truck to go about 3-5-miles tops for crawling.

With the motor turn you'll be using you could run pretty much any esc. If you want to crawl I would get something with a good drag brake. I really like the castle sidewinder. Pinion size will depend on the motor turn you end up going with.

This is kinda' hard because you have not made the switch to lipo.

realistically, all you really need are some nice high capacity (2 of them) 2 cell lipo's.... a pair of low voltage alarms (because I bet you have the older EVX-2), and a pair of small pinions... like 9 tooth. Normally I would say stock 13t, but you said you have 16t now, so that tells me you already have adjustable motor mounts.

That would give all kinds of low-end, as well as run-time.

********************************************************************

The other way would be to spend some coin on a better esc, but this means you have to come forward out from the past of nickel batteries and such.

If it were me......

I'd get:
mamba max pro esc
castle 10-amp (external) BEC (because I bet you will be using power-hungry servo's)
new titans (keep motor mounts)
smallest pinions readily available probably 8t (?)
and 2 of the highest capacity 2 cell lipo's I could find that would fit.

Ok, So I am looking at these Batteries. I would be running 2 of these batteries in my truck! My Ecs can handle up too 16v I think?

Remember, I'm looking for long run times and LOTS of Torque!

Gens ace 5300mah 2S1P 7.4V 30C Lipo battery pack $41
Discharge rate: 25C Continuous,50C Burst
http://www.nitrorcx.com/98p-30c-5300-2s1p.html

GENS ACE LIPO 5300mAh 30C 7.4V Hardcase lipo $45
Discharge rate: 30C Continuous,60C Burst
http://www.nitrorcx.com/98p-30c-5300-2s ... irect.html

Now for the Charger, I would like a duel lipo/nimh combo, But I have no idea what charger too get!
My budget for the charger would be about $100.00max

Lipo charges fast. My 4000mah packs charge in around 15 minutes. So you could keep that in mind when buying a charger. Mine is 'great hobbies' brand but it's a generic charger that's rebranded. I've had it for five years now without issue

This is the one I use

this one is similar and even cheaper.

I like that one, Would I be able to charge 2 batteries at once with this?

I did find this one!

What do you think?

The AC6 only charges one battery at a time. It's a good charger for the money, I own 2 of them and like them a lot.

The onyx is good enough, I was just trying to stay under $100 :)

But you could buy two of the AC6's and still be under a $100 I suppose ha

OK, So I went around last night looking at the few things.

Would this be a good setup to start with?

FlySky FS-GT2B 3 Channel 2.4ghz Radio System
http://www.hobbypartz.com/79p-fsgt2b-2ch-car.html

ATOMIK 55T 540 Fireball Rock Crawler Brushed Motor
http://www.atomikrc.com/products/atomik ... shed-motor

32-p 9t-Pinon Gear
http://www.walmart.com/ip/6745-Gear-32P-9T/37394112

Castle Creations Sidewinder 3 Waterproof ESC
http://www.amazon.com/gp/offer-listing/ ... S1VJ55PNCJ

GENS ACE 5000mAh 50C 7.4V Hardcase Lipo
http://www.hobbypartz.com/98p-50c-5000- ... -2222.html

AOK-BL8S Battery Checker and Low Voltage Buzzer Alarm
http://www.hobbypartz.com/79p-8003-voltagemonitor.html

Thunder AC6 Smart LiPo Balance Charger
http://www.hobbypartz.com/thac6smbachw. ... fgodN00A7w


So price wise!

1-Transmitter ------ $24.00
2-Atomic Motors---- $35.00
2-8-t Pinon Gear---- $12.00
1-Sidewinder 3 Esc------- $70.00
2-Lipo Battery------ $92.00
1-Battery Checker-- $5.00
2-Battery Chargers-- $98.00

Total $336, Not a bad overall price.

If there is anything I should change up that would be more price wise or a better setup, Please let me know.

Thanks, Gene

You dont need the low voltage detector, the castle ESC will have that built in.

If you want to continue to use your current ESC then you will need the low voltage detector.

other then that it looks good to me. I've never heard of those motors but they're cheap enough to gamble on. People really like the flysky radio systems.

I still vote to go with just one charger, only because I know the run time will be nuts with those two batteries. You wont have to stop mid day and recharge, unless you go out for 5-6 hours.

Yea, I was wanting another Esc only because I have two trucks.
The older truck has a mech-Speed Control.
So I'd figure getting another Esc and sticking the old Esc in it would solve that problem.

Thanks for the feedback guys, really appreciate it.
