we all had to learn one time or another, at one point we were all asking the questions you are.
the 2-speed incorporates another spur and pinion gear in this case that is geared to spin faster but not have as much torque. and just like a 1:1 vehicle once the engine/wheels get to a certain speed it will shift up being lower in the RPM range, to continue further.
these do differ from 1:1 though as these rely on a centrifugal clutch that has pawls that pop out (clutch is held in with a spring, once the centrifugal force is enough, it overcomes the tension on the spring releasing that pawl) to engage the second gear.
the main adverse effects of a 2-speed is more parts (more parts that may fail), and some extra weight on the drivetrain.
the above are about the main reasons why racers don't use 2-speeds, paired with the fact that most tracks wouldnt have enough room to be able to fully utilize the 2nd gear anyways.

So basically when the car goes fast enough the gs push the car into seconds gear but that means if it was in seconds gear on a jump it would slow down a lot more then it would on first gear on a jump

 

[Connor529]

Like dose that mean the cars faster but slower up hill coz the is less talk to push it but with around single gear it dosnt struggle as much ??

no, when the assembly reduces speed down to where the spring will overpower the centrifugal force again as it was before it shifted, it is shifted back into first gear seamlessly.

Post a photo or two of your truck with the body off, that would help us know what it is you have.

Ftx torro single gear I tired earlier it wont let me pic is to big for upload

Okay so what's the cons other then more stuff to fail and what's the pros

pros-
extra gearing to get more speed while not sacrificing torque off the line.

Cons-
extra parts
extra weight on drivetrain

 

[Connor529]

So over all makes it faster witch is what I was looking for so for 40 ish £ I can make the car faster yes

 

[Connor529]

Is the speed difference noticebal or little

 

[D3MON]

Is the speed difference noticebal or little

Yes quite noticeable at least in the rigs I own. it mainly comes down to what the gear ratios are used.
i could not find the tooth counts on the website for what the torro is, but the carnage NT shows:
2 speed is:
46t and 50t spurs (lower tooth count= more speed on spur)
14t and higher gear for the second on clutchbell. (higher tooth count=more speed on pinion/clutchbell) was not able to determine the 2nd gear tooth count

from what i can tell stock is 14t clutchbell (please count yours to confirm) and 50T spur gear (again please count to confirm)
so your final drive ratio for first and single speed gears would be 3.57 (50/14=3.5714)
so take off the line should be the same but will have another range above that for the 2nd gear.

Okay ngl confused me but I kinder understand and am not in a situation to take apart the car right now but am guessing your right as a guess but yh the updated is the carnage nt they r the same car only difference is the torro is longer so alot of the parts r interchange expect a hand full witch r the stretched out ones so the parts are very much there if I need to order any but yh I seen the option before as I am going the the booklet that came with the car to find the names of parts out the parts that i would be upgrading to for speed and performance are FTX6381 , FTX6436 and FTX6435
The parts on the car as stock witch is how I have it are FTX6423 and and the FTX6424 is 50 t

just kind of tech terms thing,

the gear(s) right off the engine is called the Clutchbell/ pinion gear,
the gear(s) that the clutchbell gears turn are called spur gears.

how i remember/understand it-
gear ratios is how many times the driven gear (clutchbell/pinion) will have to turn to get a full rotation out of the spur gear.
so that clutchbell will have to turn 3.57 times to get one full rotation.
running 30,000 RPMS that most nitro engines peak at thats approximately spinning the spur gear at 8,403.3 RPMs (At peak) to the diffs.
*(lets say for example the 2nd gear on clutchbell is 20T)*
gear ratio would be 46/20=2.3
clutchbell spinning at 30,000 RPMS under a 2.3 reduction would be about 13,044 RPMs (At peak) to the diffs.
(do remember that diffs also reduce down as well).

bear in mind, there is rotational loss from the clutch shoes to the clutchbell, and there is rotational loss from the components (i.e weight of driveshafts, gears, etc.) on the engine. RPMS are given for example/explanatory purposes.

Okay so when my dad said the second gear could put the car max speed up bye 20mph he wasn't bull shitting me that much

i dont know exactly what it will be but dont think that will be too far off lol

 

[Connor529]

Wait what I acc fort u was gonna say that's a lil over the top like but dam so my car rn peaking about 40/50 50 at a push and ur saying just alls av gotta spend is £45 at most and it's just Casually goes 20 about 20mph faster why the fiddlesticks am I looking for a new engine fiddlesticks that this site is amazing come here expecting advice but not only did I get advice saving me money so thank u ahaha but no honestly thank u looks like av got little time to drop hits oh yh just get me the ftx 2 speed gears box oh dont for get the clutch ball dad ahhaha narr gonna be fun not only sad thing is the car hates turning as it is top heavy dont now how to stop it rolling when I turn takes about 30 foot over room to turn it after full frontal I mean I go little bit to much but am not flipping it then running to get it and run back ahaha

Can you post a link to the specific truck you have?

I don't know the truck, but replacing what you have now (single speed via slipper or center diff) with a 2 speed will remove your slip point in the drive train, so you will have to be careful how you drive it more if that is the way you go. I had that issue many many years ago when I had an XTM mammoth. It came with a two-speed, which seemed to cause more problems than it was worth. Then I went to a center diff which helped the front/rear diffs last longer, but really killed the speed of the thing. Would have been fine on a track as a single speed ST (very big ST), but as a basher, I really missed the 2-speed. Now I won't even buy a nitro if it's not a 2-speed... or at the very least, I'll think long and hard about it before purchasing.

Now that I have a grass bmx track to run at, I could really run a balls out 1/8th buggy or something similar there that is a single speed and not be too annoyed about it. Before I found this place, a lot of my running was big flat areas with a few jumps here and there (or skate parks) and a single speed anything just didn't get it done.

I'm more into electric now anyway, so it's not a huge deal one way or the other. But I do still take a nitro out once in a while.


EDIT:

Actually, looking at the manual, it appears the center/spur gear is solid mounted, so having a 2 speed won't be any harder on things than it is in stock form, other than allowing you to gear it better for low end torque and high end speed.

Was a pain finding a manual!

Yh sport on mate that's the truck so from what am understand going to the 2 gears is a good over all option for me

Sorry to restart this thread. This is the starter nitro car l am looking to purchase (first nitro) next week. Have had electric in the late eighties (yes that long ago) loved it and will probably get another electric in the future. However just wanted to know how you got on with the torro. Just making sure it is this one https://www.modelsport.co.uk/ftx-torro-1-10-nitro-trophy-truck-4wd-rtr-blue/rc-car-products/443423
