Newb question about Truck Wheelies

[Jeep]

I've watched alot of video on rc's lately, and in alot of them I see trucks easily pulling the front wheels up and keeping them there.
My question is , Do trucks normally not have a center differential? Or , is it that they have a limited slip center differential, or, do they have a center differential and simply run such a heavy weight oil and are top heavy enough that there is enough torque still applied to the rear wheels even when the front have no traction?

I ask this because my buggy with a center differential won't even come close to raising the front end.

I'm not trying to wheelie my buggy, I'm just curious, that's my nature

We had one guy here that claimed his buggy wheelied, and on occasion, by accident, they do. By accident I mean just the right combo of bump, weight trransfer and power. It is near impossible to do one on purpose.

MT's use the slipper clutch and transmission to get power out. I am not sure if that has any bearing on why they also do wheelies, but the Revo is one of the harder ones to get to wheelie while stock, so it may have more to do with suspension design and set up as you note.

the buggys have the diff. makes a normal wheely imposible. a mt both the front and back diffs turn at the same speed. no center diff. the revo is just hard to wheelie because of the super plush suspension and the low center of gravity

 

[truthseeker]

a center diff will cause the wheels that are spinning to get more power, so if you pick up the front wheels on a buggy, all the power (well, depending on how thick your center diff fluid is) will go to the front and the back will quit pulling, thus putting the front back down. most MT's don't have a center diff, so even if the front wheels are in the air, the back is still pulling as usual = big wheelies if you have enough power or a stiff suspension.

with Mt's it depends on the gearing and the motor. Mostly gearing. I'm not to sure how the buggys are setup, but Id imagine the gearing plays a big part in that as well.

LOL...I saw a buggy do wheelies....seemed almost on command and we were all amazed..thought it was just the WS72 (when it first came out) ....come to find my buddy thought he put 10k weight in the center diff....it was 100k!!! DOOOOOH!!!! he's thai and didn't speak "engrish" too well when he bought the oil and other part for his "Levo"......funny stuff though....

I've got 50k in mine and it still unloads a bit in the front.

Thanks guys,
I kinda figured there must not be a center differential in the MT's.
Just wasn't sure.

The main reason you will NEVER see wheelies with buggies,even ones using the most explosive nitros or brusless is the center of gravity is very LOW.

With trucks say like the Savage the center of gravity is high,very high compared to a buggy.And wheelies are easy,providing you have a well tuned engine or at least a BIG block.

A buggie could do wheelies,but you would have to be on a very grippy carpet,have the slipper nearly locked and use an extreme brushless.

Even harder would be making a on road racer wheelie,there even with rocket like acceleration the center of gravity is so low,its hopeless.
