Hey rene what motor did you use in that vid?

I didnt want a crawler, I wanted speed. I have crawlers already, and the revo is not a good crawler, so I didnt go with a 10 pole outrunner. This one with big maximum doesnt cog any amount worth mentioning. :027:

Look at the vid again serum, its still spinning the front tires way faster than the rears. At 10k, it wouldnt be impressive....it would be retarded. It wouldnt get out of its own way, litterally. I would be money it would take 30 feet of spinning on asphault to even get moving good. The only way it would wheelie is when the front tires would balloon so fast the front end lifts off the ground for a breif second. With 10k, you would swear its front wheel drive. :028:

this one is, it handles at least 6 different batteries, and I am sure you could fit more in it. Need to fit 14 cells in one? Buy a gorilla. This isnt our first BBQ .....:028:

Good to hear you like to bbq.. The bpp truck got me worried for a while..

Viruss has his 4S powered lightning with an even lower CG doing backflips at 30 mph+ on a 1930/8 motor. with 50K oil in the diff..

It's rather hard not to get pancakes on the front tires. pancakes loose grip, due to a small contact area with the track/road. I think it would be wise if they started making threaded tires.

Perhaps i should say 'in my very own opinion it would be more impressive if it did that with 10K oil', In other words; I am personally not impressed by a truck that does backflips with 300K oil in the centerdiff with 2500 watts of power... It's common sense (IMO)

@ leroy; that was a 6pole 1350 Kv motor that was in it.. If you are interested, i have got it laying here.. Doing nothing with it..

A lightning stadium is a whole different creature. We ran 100K on those w/2500watts. It was a simple short video, people asked me to post a video, the camera died when the video ended. The gorilla has no center diff, and is shorter for comparison. You can see in the video, the diff is working...on exit of corners it will still pancake one front tire. I could care less what weight oil it is, I use what works. This truck is only 1700 watts as it sits.

bbq probably isnt the best word to use around a new project like this, as many other projects ended up with some degree of bbq involved....not to mention the ever so calm nomadio girl....overheat:026:

as far as the diff goes, i really dont think its worth the time to discuss how impressive it would be with 10k in it. we all know that damn near any bl setup would pancake like crazy with that.
but i do understand and agree serum that if it can violently flip with 10k in it, then it may be overpowered..:005: ...but i dont see anyone even trying it to see if it would do it.
i know serum has tried many different setups and unique designs, so constructive input would be appreciated and welcomed

Here is a vid of a monster gt mbx center diff and 10k oil in it.

thanks for posting the video, as you can see...not impressive with 10K oil. It will pop the front tires in the air and then lose 70% of power by spinning the rest of the time.

I will get video of some track time to clear everything up, and show off some power. :027:

Well I guess if you are producing real power on the roof.
You are the man. I don't know how you keep traction with tires off the ground.

So if your primary goal is to keep the front tires from spinning and wasting power, why dont you just run a transmision or center spool and tape a brick to the front bumper?

The only issue I see with that one chassis is the motor getting hit if you land a certain way.

The battery being on only once side can be a problem, but if your battery isn't excessively heavy, it can be easily offset by having everything else on the other side.

I don't think one brick is enough jhautz. You might need a few lead bricks to hold down 2500 watts.

You could always try a torsen center diff. The torsen should keep the front wheels from unloading so much.

sorry, I cant drive and do a controllable wheelie,steer, and video it all at the same time. I have no trouble driving it when not recording it. That was actually the only time its ever flipped over backwards, usually just spins. I figured a video of me showing throttle control and not letting it spin/wheelie would be boring, so I went for full power....my bad guys, I can tone it down next time. :005:

spools break, and break parts. It has a transmission. The diff takes alot of the shock off the driveline. Its perfectly set up for my track and driving style. It wont flip over frontwards when hard braking, and doesnt flip over backwards in normal race conditions. I get max power when I need it, where's the downside?

And coolhand, I wasnt implying the truck in the video was slow, but its clearly wasting alot of power. Experiment with heavier oils before you stick with that, you will be much happier. 10K is rediculous for something like that.

LOL, we need to end this useless discussion somehow..

Let's figure out a way to change the resistance of the centerdiff without the need to remove oil.. (thickness of this oil is track related.. ) a torsen diff won't do what an adjustable one can do. Team Magic did put something in their M1 diffs, but i don't think that's a durable solution. It will wear fair quick IMO..

Serpent found a way, which basicly works like a slipper, outside the actual diff, i will post of a pic of this principle later..

10K in a centerdiff makes NO sense at all in an MT.. i was just trying to make clear what would impress me more..

You forgot to include the word 'YET'.. Mike is currently working on a slipperential for that vehicle.

Not trying to put you, or your products down.

Let's be friends and have a group-hug.. I'll be the one in the funny looking costume..

It's hard not to get pancakes in the front, but like i said; we need belted tires..

I posted video for the simple fact is.
You stated the 10k diff oil was just no good.
Yes I know it shifts alot of power to the front wheels.
I know I could go up in diff oil weight.
You can loose or gain power thru a diff by not the weight of the oil
but how much you have in it. If you don't get a diff completely full
the diff will operate and push power to less traction area easier.
I have 30 k oil in my gmaxx and it rides a wheelie like crazy.
I am loosing speed and power for the back bumper is dragging.
Don't worry. That is not my fastest truck.

Thats a good idea. One of the cooler ways to do it is electronically change the oil viscosity, can be done on the fly. It will get to that one day, where you can loosen it for one section of the track.

And yes, I know the gmaxx CAN have a center diff, several already do, wasnt my point. 300K is not locked by any stretch, like the typical Gmaxx which is also shorter.

Coolhand, I cant stress enough how much I didnt mean the truck is not fast, its at the top of the class for sure. I thought you were posting it to show how little power made it to the rear wheels. Those low oil weights are meant for nitro which build power slightly slower and hit slightly softer which greatly affects the oil choice. I can remove the rear driveshaft and still raise the front tires, but whats the point. I like the feel of an almost locked diff, I raced the E-maxx for years, and the feel of losing 70% power just doesnt feel as fun to me. I like the hard accelleration. Anyway...does anyone care this much about diff oil to discuss it this much? I dont, I am done.
