Revo 20/40...If this is the case then why doesn't it move as fast as Jato ?

[kgz2012]

I hear a lot of Revo 20/40 for gearing....But if this was so great then why does the electric Revo go 35+ level 2 and the Nitro goes 45+ level 4.....but the Jato 3.3 goes 65+ level 5...do u guys see what im seeing ?:eek:

[iracechevys]

The Jato gets up to its speed faster with the gearing it has, The Revo has more rotaional mass in the TRANNY in the diffs and turning those monster tires and propeling a heavy truck, where as the Jato is light, its trans. is geared differently and benifits more on top-end from Revo gears.

You are kidding right? The jato is a lightweight 2wd truck that is designed to be fast, the revo is a big monstertruck that is designed to be fast, but not stupid fast like the jato...it is not geared for the same thing as a jato...

Basicly what I explained just in scientific car terms.

I was already typing before you posted...

That made no sense...lol...i sort of get what ur saying but I think they're both meant to be fast but one has more weight capacity than the other......lol....but dont they both have a TRX 3.3...meaning that they both should at some length point meet at the same speeds....

The revo is alot bigger and heavier so its slower. THe jato is is alot lighter so its faster. Its like putting one of these engines in a car and say it goes the same speed. The rc will be faster

Erevo. Electric, but big and heavy. Harder to drive
Revo. Nitro, big and heavy, pretty fast
Jato. Nitro, amazingly fast. Very hard to control for a newbie

you cant tell me that these two go the same speed

...no...just think about it in common sense terms, forget the sience.\

so why would 20/40 would be any good for the jato besides it giving more torque at the line !!!

[rustler 007]

Ok. Let me break it down to u

Revo 20/40 gearing has a higher gear ratio than jato gears. Therefore it will go faster.

[RC_K1d]

The closer the # of teth are on the 2 gears...the input gear is spinning 1 turn the output gear is spinning 1/2 turn or whatever...something like that...

Shouldn't you have learned that riding bikes or something?

[RC-MXer]

It dosn't matter if the revo goes 45 with those gears, it has bigger gears in the transmission thus meaning they take longer to make a full revolution which mean more torque( think of it like a mountian bike. first gear is huge and really easy to pedal) for a big truck. but the jatos are small meaning more revolutions.

[newb-rookie]

think of the monster trucks with a thousand + horsepower. now ask yourself if it would go just as fast as a 400 horse camaro? the weight of the MT makes the differential gearing and transmission gearing built for torque. the jato doesnt need as much torque to propell it so it can benifit from gears that will make it go much faster due to it being so light. as long as the tires spin and the front end comes up on a jato, you can change just the spur or cb in order for it to go faster but accelerate slower eliminating tire spin and wheelies. basically the trans and differentials seperate a 15lb truck from a 5lb truck

[kgz2012]

ok...i get it !!!! but now. why do we put such stress on the tranny gears with 20/40..2:1 ratio. I understand ratios more...but why not 24/48. that is still 2:1 ratio with less revolutionary stress, has anyone tried this ?

[Desert JATO]

i believe that jato is faster than revo because of the weight/hight/ and maybe the internal gears of the revo ( but not sure of this last point )...
