dirt kicker

hey guys .

i am still an ametuer rc truck racer and have bought my self an Himoto emxt-1 and have seemed very pleased with that for a year , but now i want to only upgrade my motor as i have built a trailer for my boat and helicopter and now would like to start towing tandem , the motor i have now is a stock 540 size , preferably i would like to stay in the brushed range now , do not have the finds to convert everything to brush-less ,

i need a motor that have a lot of talk and i bit of speed at the same time ... i need to toss up some choices please help !!

thanks

if you want to stay with brushed motors you could try a "stock race" motor like the trinity c027.
tamiya also make a nice variety of brushed motors, the gt tuned 25t, the superstock bz 27t, just search "tamiya motor" on ebay and you'll see them all.

stay away from venom motors, i have a couple of them and they are very low on power, the trinity and tamiya motors are much better.

Thanks , and would that be able to tow my whole rig WITH MORE THAN ENOUGH POWER ?

Brushless setups have gotten so cheap and are so much more powerful than brushed, that it doesn't make sense not to get them if you want more power. With a truck like that, the cheap ESC is going to limit your power just as much as the cheap can. You'd have to upgrade them both to see any marked improvement, and at that point, you might as well go brushless. HK has a [link=http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10438&Product_Name=Brushless_Car_Power_System_3600kv/35A]cheap brushless combo[/link] that will give you more power than you could ever need in a 1/10 truck.

thanks , how would i get that to south africa ? and will that be the end of my search for more power

dirt kicker

would a 5200 KV be good enough to haul my tig in out easily ?

HK is based in China, so I'm pretty sure they'll ship anywhere. 5200KV is too high for a 1/10 truck, especially if you're towing something. Higher KV ratings mean higher RPM, but lower torque. The 3600Kv motor in the kit I linked is even on the high side for 4WD, but you can probably compensate for that with a smaller pinion. Power-wise, it'll have more than enough.

dirt kicker

does that mtor have the torque i need ?

Even at 3600Kv it will have significantly more torque than the 540 can that comes with the truck. It will be a lot faster, too.

these are a HSP truck, they come with a 3300kv motor in stock brushless form, and a 7.2volt nimh.

I'm running a 3s lipo in mine, with a 26t pinion in place of the 18t stock.

it overheats, but its fun!

if you're only going to run the lower voltage, and stock gearing, you'll have no issues with the 3600kv, but if you plan to use higher voltage, you'll need something around 3000kv.

I have the himoto mega-e MT10. This is similar to the emxt1 and if the emxt1 is geared like the MT10 then in stock form with the brushed motor it is waaay overgeared.
When i went brushless with mine i went from the stock 23T pinion down to a 19T pinion and smaller diameter tires with a 3350 Kv motor.
With that gearing i am able to run either 2s or 3s in grass without any overheating.

Stick all your info into this calculator: http://scriptasylum.com/rc_speed/_top_speed.html
and aim for a final gear ratio of around 10 or higher and use a motor less than 4000 kv and you're set!

Also check your motor, esc and battery temps. to make sure they are in the safe range.

One more thing to note is that you may have to upgrade to steel diff gears if you have plastic and your drive cups and center dogbone will begin wearing quickly. You may encounter a couple twisted dogbones along the way too

dirt kicker

thanks guys !!! would a 5200 KV be over powering it ? IM LOOKING FOR SPEED !!!!!!!! and some torque at the same time ...... the ESC has overheating and overcurrent protection

genitor

Look for a motor in the 3000-4000 kv range.

dirt kicker

could i not run 2 motors but use the same esc . like when i feel like speed . 5200kv and when i feel like power 3000 kv ?

Candre23

5200 is too high for 4wd off road 1/10 scale. You'll just end up overheating the motor and ruining it. 3000-4000 is where you want to be. Trust me, it will be more than fast enough for you.

genitor

The better approach would be to use one motor in the range 3000-4000 kv and increase your voltage or gearing for when you want more speed but keep a close eye on temps.

The bz is 23t


Tamiya motors are very good


Dirt tuned - 27t

Super stock BZ - 23t

Super stock TZ - 23t

Super stock RZ - 23t

The b/t/rZ motors are the touquiest of the lot

The rz is the fastest by a small tad

bz is the best for what you want

dirt kicker

THANKS !!!!!!!!
what speed would i be getn on a brushless 3600kv running 3s lipo ?

answer in MPH is fine
thanks !!!

TheyDontWantMusic

it should do about 80kph, but I reckon that motor is too fast for 3s in that vehicle for hard off road use.

dirt kicker

thanks alot buddy !!!

so what battery would u recommend ?

dirt kicker

hey , im ordering this motor today ,,, is this the right choice ? ,,

answer urgent please

TheyDontWantMusic

which motor?

dirt kicker

the 3600 kv ,

The motor will be fine.

Dude....if that is what a 3600kv motor will do, thel ill defenately stick by my brushed. I got the same Himoto truck as Dirt Kicker, and swapped the pinion out to a 17t for speed and atatched that to a modified 17t tamiya motor....(one i got from a guy why "whired" them), and im getting 70km/h with a gps sensor attached.

Im currently in the process of getting a setup ready for my himoto....4.5 trinity brushless....its overkill i know but im not in for racing on a track, NOOOOO......im in for killing a certain traxxis that i cant catch up to once it hits second gear....

By the way Dirt Kicker......dont depend on the stock ESC that you got with your car......once it gets too hot....and i mean....ONCE....it wont cut out for nothing..........!!!! Im now using a LRP ECS...and it super for now
