Sorry for taking so long to check in to this thread but here's what I *think* I'm running in my MBX-5T, I'll double check later.

Front: 10k
Center: 100k
Rear: 7k

All fluids are Associated Silicone Diff Fluid.

I only run mine for bashing and I've found that putting 100k in the center was probably the single biggest improvement I have made.

Bashing Pros:
-Explosive grip/acceleration means I can get a really big air off of jumps even with only a few feet of running space to gain speed.
-Fun on loose surfaces since you can get some nice powerslides going.
-Much easier to do a rolling wheelie if I want to.

If you ever want to see how mine handles let me know, we're both on Cape Cod after all.

I went thicker in my center, I think it was 40. I can't remember right now but it seemed to give the truck better control, stability, and overall drive. I still need to tune it and try some different setups so I'll let you guys know what I come up with.


:D

Little update...

I've gotten some wheel time on the Mugen ever since I went with truggy as my only class. On small tracks, a smaller car is ideal, 1/8 buggy is tight, truggy is pushing it and I generally don't race on the small tracks anymore.

However, I brought my truggy home with me and the track down here is HUGE. I had the fastest lap time in the first heat of racing yesterday and the truggy did great. It actually felt really good and pretty stable with the way I have it now. I want to get a little more steering so I might go down in fluid up front but I'm not sure what's up there right now. I want to try 10K and see how that does. I could also tear apart the rear and put some 5K in there - opinions? Thoughts?


:D

would thicker or thinner oil decrease tire ballooning? have adjusted trottle curve so ballooning is less but it is still happening 3/4 down back straight or if i give it a little to much to quickly out of corners.

Thicker in the center so it will transfer more energy to the back tires.

Wow . I think that's too thick for a truggy setup. I'm running 7K front, 30K center, and 5K rear on my truggy.

Post your brushless setup - motor, speedo, batts, gearing, tires, wheels, etc etc.

With too thick oil in the center the car will lift up the front end a lot when accelerating, which will balloon the front wheels and need a really gentle throttle finger. On the other hand, really light oil will cause most of the power to be unloaded to the front wheels, which will again balloon the fronts and also rob the car of acceleration.

The thing to remember is, you WILL have some ballooning when running WOT, but if it gets really bad, it may be because your car is over geared. And if that's the case, you could gear for lower top speed (which will cause wheels to rotate slower and hence balloon less) or do something like taping up the tires on the inside so they don't balloon.

I've had the opposite effect for me and my front and rear tires have the same amount of minimal ballooning, especially after going to thicker in the center.

I also limit my front droop, which keeps the tires planted and the weight balanced for good acceleration.

Are you still running the 10k center oil? I was talking more about 50k and higher when I mentioned thick oil in the center. I'm currently running 7k in my center, but that's just because I like the front wheel drive action I get from it. Personally I wouldn't go higher than 20k in the center when racing.

The front droop is a very good point too. I also found the car has better on power steering when I limit the front droop.
