ok I converted a Jammin X1x CRT to BL the other day, and well it wheelies like mad. More than my Savage X... Seriously

http://www.rcuniverse.com/forum/m_9867005/tm.htm the build thread it has videos of what I mean in it.

Anyone have any Diff fluid recommendations I'll be completely honest I have no idea what it has in it already. I'm guessing its the stock fluid (or whatever ofna puts in it)

well the lighter the diff fluid the more ur wheels spin. so maybe try putting a lighter diff fluid in. it seems like the dff fluid ind the back is to thick. just change them.privatemessage me for any other questions.


REAR-7000
Center-10000
FRONT-5000

thx for the recommendation. I've not dealt with diff fluid too much.
I'll have to pick up those 3 when I hit up the hobby shop next time (hopefully this week)

might drop the center to 5000 its still pulling wheelies but not as bad. I also dropped it to a 12t pinion almost tempted to slap my 11 tooth on.

Also it had no fluid in the front of rear popped the diffs open to find them bone dry. Shouldn't have expected any better seeing the crap shape the roller was in when I got it

HRCules77

My Feedback: (4)

Thought I'd post some basic specs I've found (but don't remember where) for truggy diffs:

Starting Set Up
FR: 10K
C : 20K
R : 3K

Bumpy Conditions
FR: 7K
C : 10K
R : 2K

X-Loose Conditions
FR: 7K
C : 10K
R : 5K

What is the oil doing in the diff? For all vehicles:

Front
Thinner:
1. Increases steering into corners (off power)
2. If the oil is too thin then the steering may become inconsistent, especially losing forward traction (and steering) during acceleration out of corners

Thicker:
1. Increases stability into corners during braking
2. Increases steering on-power at corner exit

Center
Thinner:
1. Front wheels unload more during acceleration
2. Decreases on-power steering (reduces over-steer)
3. If a high power engine is used you could waste too much power and sometimes "cook" the oil in the center diff because it "overloads"

Thicker:
1. More all-wheel-drive effect
2. Better acceleration
3. Increases on-power steering (reduces under-steer)
4. Better suited on high-bite, smooth tracks
5. Car can be more "nervous" to drive especially if a high power engine is usedsmooth throttle increases may be necessary

Rear
Thinner:
1. Increases cornering traction
2. Increases steering into corners

Thicker:
1. Decreases rear traction while cornering
2. Reduces wheel spin

I am using a very high power motor in my truggy. That being said, I believe I have 30K in my center, 10K in the front and a mix (10K+5K) to approx 7K in the rear. My truggy is very stable at high speeds, puts the power down well but lacks somewhat in off-power steering.

Hope this info helps.

thanks might drop to 5k in center to unload more power to the front seeing that seems to be my issue
Since I put 10k in the center(what was in it looked alot thicker) its not wheeling as bad (it was doing backflips with ease) but its still pulling them up
