if the gears held up on the jato with a picco .26 how much faster at top speed would it be than my faulty 3.3 which does about 55mph and also what would it do in 0-60 because the 3.3 supposedly does it in 4.2 seconds so the picco could do it in under 4 probably. what do people think

wont be faster because the .26 isnt as fast, RPM wise.

Also a bigger engine might not make it faster. If you tires dont grip you wont get the accleration. I hear the os 18 is just as fast or faster then the 3.3. That will be my next engine when the 3.3 dies.

Need to go with a good .21 M8[&o]that will smoke em[sm=thumbup.gif]

.21's make more rpms than .26's, but both make too much power for the drive train. dont always think the bigger the better, and dont go by horsepower either. rpms and torque are what to look at. a .12 can make more rpms than a .18 and can potentialy create more torque.

Takes weight and thrust to make torque the handy cap is in the gearing

i have 6 tanks on my .28 wasp. i run onroad only, still no drive-train issues. massive torque, seems a little faster but have not radared it yet.

how come that a revo 3.3 does 45mph and my friends revo with the picco .26 does 55mph so the picco is obviously going to make my jato faster.

Ok go ahead and drop in the .26, but dont come whining on here when your jato only goes 25.

why will it only do 25. some people say that with a single speed conversion kit it'll do mid 60's and get there very quickly indeed, and if it did only do 25 then why does everyone with a revo 3.3 upgrade to a picco

the revo is a 1/8 big truck so it can handle the power of a big block but the jato is only a 1/10 and isnt desighned to cope with big block 26's . and that is a load ov crap abwt tha revo doin 45 with a 3.3 and then a 26 doin 55 i cant belive that !!!!!!!

well explain why he beat my jato with a well tuned 2.5 in a 100m drag race then.

cause he has less wheel spin, hes AWD, your only 2wd.you cant just pull the throttle full bore, he can. i didnt mean it woul do 25 literally, just a figure of speech meaning it would be slower.

even if my jato with a picco can only do 45 it would get there quicker than a 3.3 right? o and my jato doesnt wheelspin i hit wot all the time on tarmac and it has fantastic grip

awd slows you down...its extra weight

thats just stupid !!! slow u down if you put a tz in a jato it would wheelspin until u let off tha throttle but in a revo it would be awsome !!

thats why you baby the throttle...and if you put a big engine in a revo it will wheelie anlong with the jato, so awd would be useless till you let off

wheelies in general slow you down, its added wind drag, engine stress, and less off the line grip.
the best thing you can do with any wheely monster that you just want to remove the wheely bar and place the batteries in the middle of the chassis, and soften the rear shocks. it will squat and shoot off like a rocket, and will prevent you from flipping over. my mt with a cv-r .18 is stupid fast off the line and it tops out at about 43-45mph around 2.7 secs, and i can peg it and dont have to worry about flipping over (except when its lean and on cement)

and all wheel drive adds bearly any weight, its like adding another 2AA batteries and thats it. most your weight comes from the suspension and tires.

Wheelspin? On pavement? That's extremely rare. Most R/C tires, unless super hard, have plenty of traction to flip the car over, wheelie-style.

Regarding the .26 vs .20 argument, assuming both have the power to push the vehicle through the air (and drivetrain friction, rolling resistance, etc.) to their maximum rpm, it all comes down to that max rpm. If the 3.3 can do 35,000 rpm and the Picco .26 can pull the same, they'll hit the same top speed. Whichever revs higher will potentially be faster, displacement is not the only factor. You could drop a 400hp Chevy 350 in your Jato, in theory, and probably hit about 10mph for a top speed. No shortage of power, just a major shortage of rpm. A nicely-built, street-oriented 350 Chevy will rev to 6000 rpm, while an R/C engine will do 35,000 or so. Assuming the same gearing, the Chevy-powered vehicle will only be able to achieve about 1/6 the rpm of the R/C engine-powered vehicle.

So that's what it comes down to: gearing! If you can, gear the truck taller for the Picco, meaning a larger clutch bell and/or a smaller spur. My RC10GT could do about 35-38mph with an O.S. .12CV-R engine and probably less with the "sport" .21 I installed with the stock gearing. But I changed the bell/spur gearing from 16/66 to 18/47 and was able to exceed 60mph (clocked) with the .21. So more power is good....as long as you use it properly. My next project is to drop a Picco .28 into the GT with a 20 or 22-tooth bell and 47T spur and shoot for 70mph.

All that said, the Picco will have more power at nearly every point in the rpm range than the 3.3, so yes, it will arrive at the top speed faster.

now remember, we're talkin bout a jato, which has no grip whatsoever

LOL! I wasn't aware of that. Okay, first put some decent tires on there, and THEN go for speed! Or better yet, first things first. Bolt on some Masher 2000s and see your top end increase by about 20%, assuming the engine can pull to the same rpm.
