very powerful motors

[Matt2000]

hi, does anybody know where i could get a motor with more power than 27T, that's the most i can find. i am really close to ordering my pajero, i've decided to get it from tower

i'm hoping to modify parts on it, like the msc to an esc. i am going to sell the msc on ebay

If you mean more turns than 27T then I haven't seen any, but if you mean more power than a stock Maubuchi 27T then there are plenty. The Trinity D2K has more power, the Monster Horsepower engines are pretty torquey and a 550 motor like you find in a E-Maxx has more power than the 540s do but requires 14V which in turn would need a special ESC and 2 battery packs. Note that power does not equate speed. The less turns a motor has the more speed but the less power and vice versa.

[DJTheo]

To clarify a bit the terms, as what themonster calls power is actually torque:

Power = Speed x Torque

More turn motor: usually higher toque, less speed and less power (as torque isn't that higher then speed is lower)

Less turn motor: opposite to above.

Power = Torque x RPM.

A lower turn motor is more powerful, but it delivers that power over a wider speed range (assume flat power curve therefore linear torque) and hence torque at any one point is less than that of a motor with more turns (ignore the number of parallel winds here). Consequently the motor is more powerful (draws more current) and the car is ultimately faster (higher rpm) but the torque band is much wider and somewhat diluted hence it doesn't feel quite as punchy.

Looking at two motor's dyno outputs you will see that one has a fatter area under the curve - this is the 'torquey' motor and one has a narrower but much longer graph, this is the 'speedy' motor.

I hope this makes sense...!

Thats the best reply I have seen to that question.

And in answer to Matt2000 question I wouldnt suggest anything more than the mabuchi 540, I have used a Trinity P2K2 and to be honest even that is too much for the chassis, you want a motor with moure torque not more speed - LRP Truck Puller or an Eagle comm lathe motor (55t) would be my choice.

[Matt2000]

i want more torque, to make sure the pajero can get up steep hills, and trough mud, without getting stuck, and the wheels stopping

[theMonster]

What you want is a Trinity D2k or Monster Horsepower motor. If you can find a 27Tx1. Most motors are XXTx2. If you have 4 27T motors they can range from being most powerful to the fastest in this order 27tx1 27tx2 27tx3 27tx4. There are other things that can affect this as well such as the kinds of brushes and magnets used, but getting into that may get too confusing, that's why I'm suggesting the motors above or trying to find a cheaper 27Tx1.

[Matt2000]

i'm not confused, i know a bit about brushes, i am looking at some from CML distribution. the site says they are built for more torque.

i'll try and get the page, but i can't get into the site right now, if you want to try yourself the site is www.cmldistribution.co.uk

Kyosho do a Magnetic Meyhem truck motor, that is 22 turns but seems to be very torquey, approx £40.

I've also seen a guy on ebay selling 80t, really low speed truck motors which I'd imagine to be ideal for an XC chassis.

[mr_pushrod]

I wouldn't advise lower turns than standard, it'll make the Pajero a lot faster. I ran a 19 in mine and while it had plenty of pull, it got very hot with all the crawling which will kill the motor. Also as Biggus said, the chassis can't take that amount of power in terms of handling as I found out on his and mine[:I]

[grusomkis]

Put a brushless in it, and i guarantee you will have all the power you want. LOL

[Matt2000]

what's the difference between brushed and brushless. the only thing i know is that they are more expensive!

i've seen a 27T motor on models in motion for only £15. it looks good, would it make my pajero any more powerful

[theMonster]

Again, it depends on the magnets, the brushes and whether the case is a ball-bearing type or not. If it is identical to your current 27T in those aspects then the only way it'll give more power is to be a 27X1 where as the stock Tamiya is a 27X2. The team Orion website has a lot of good info on brushes and which do what, but then again it doesn't sound like you want to build a motor, you just want to buy something inexpensive and powerful. Try this, I think it's PERFERCT for you, cheap and it's a 27X1.

[Matt2000]

that looks great. i'm buying the pajero from tower anyway, so i can order that at the same time.

one other thing, does that motor come with the tamiya bullet connectors

[netsmithUK]

I'm about to install a LRP Truck puller motor in my XC, which makes it top speed about walking pace. On the plus side it then has the torque "To drive up the side of a house" as Disco would put it.

These are about £30-£40

Any idea where you can get that Eagle lathe motor and how much it costs? I was only aware of 'puller' motors from LRP and Orion (80 turn) and the latter seems to be obsolete now.

[theMonster]

From what I can tell by Tower and Kyosho's website, the ION STORM does not come with the bullet connectors unfortunately, you may wish to confirm this with Tower though. They're not hard to solder on, but you'll end up spending a few bucks on the wires, solder and iron if you don't already have one [V] . You can get a nice cmall solering iron from RadioShack for $7. 45 watts should do it, you could probably use smaller, but you'll regret it later down the road when you want to solder thicker stuff.

[mr_pushrod]

The Eagle com lathe motor is £25 and you should be able to get it ordered from most decent model shops.

Thanks buddy [8D]

[Matt2000]

thanks for the info about the lathe motor, i have seen one for £26. it looks really good.

[jimbob4000]

wouldn't a 55t motor get really hot and burn out or something like that.

i have heard that the more turns the hotter it gets, might it melt the plastic chassis?

Adam

[DJTheo]

Low turn motors have more power and thus run hotter, a 5T would proabably melt most gearboxes.

[jimbob4000]

Oh well, my mistake.

I live near MATT2000, and i have quite a powerful soldering iron which matt or i could use to solder it.

[GPZ1000RX]

I think someone has misread Jimbobs question.

He asked if a 55T motor got really hot, not did a 5T motor get really hot!

The reply is technically correct, a 5T motor will get very very hot and probably melt things.

A 55T motor will run very cool indeed and make lots of low down pulling power (torque) but not many revs. A 5T will rev like crazy but won't make much low down torque.
