Thanks E-MAXX.

Anyone know the answers to the questions? I would really like to have an extensive test today of it.

hows it run?

Runs absolutely awesome!! ...besides for the few problems on page 4. Mainly, it doesn't roll freely, but thats because there isn't enough oil in the center diff. Anyone have suggestions for a certain weight?

I also got some video clips today. :027:

try 20-30k wieght in the center diff and start from there. i am not sure about the lipo, but i have always heard to store a lipo charged(so if your charger can top it off that might work)but not sure, but if i am not mistaken as long as the battery is not pluged in to anything it can sit saftely but dont take my word for it. sorry for not knowing the other questions.

Depends. If you don't plan to run it for a few weeks, I'd leave it the way it is since it's probably at about 3.8v. If you plan to run it sooner, I say top it off. Just make sure that whatever charger you are using auto-detects the right number of cells if it has that feature.

Would it be all right to have it is completely empty? Like about 12 volts?

What will the differences be between the 20k and 30k?

Thanks guys.

The higher the number the thicker the oil, meaning more resistance to the front and rear outputs spinning at different speeds (less slip).
Does the manual have a recommended weight written some where. The manual for my 1/8th truggy recommended 5000, 10 000, 1000.

No, this buggy is about 5 years old. It is the previous model of the XT2. I also am running a Hot Bodies center diff if that helps. This is only for bashing, so I don't want to be rebuilding the diff all the time and trying new oil. I am leaning towards 20k right now... but still not sure.

06.18.2007, 02:48 AM

id do 30... 50k i duno

There's no right or wrong weight to get. It's just what works best for you, and that can change depending on what sort of surfaces you drive on and what sort of driving you do. People often use between 10k to 100k+, but 20k or 30k is a good range for off road racing.

I personally wuold not leave it sit @ 3.0V/cell. It will still self-discharge some, and if it drops below you'll frag your batt. Leave it charged somewhat at the very least. Looks great other tho.:)

BrianG · 06.20.2007, 11:49 AM

Although, even a dumped pack should not read 3.0v/cell after sitting for a while. They usually drift back up to 3.4-3.7v/cell after sitting for 20 minutes. If they stay at 3.0v, then they are probably being discharged too deep and you should increase the LVC a bit.

Ok, I'll do that... thanks guys.

Well, I just spent a lot more money on this thing then I was hoping to. I just sold the EOS1210i, and bought a Superbrain 989. Mainly because it comes with a power supply. But not only that, I saw a sweet deal for a brand new DX3.0 for $160 including shipping on ebay, and since I didn't even have a radio system, I couldn't pass up the deal. So hopefully I'll get all this stuff this week, so I can officially finish Project XT1 :cool:.

Just one question, I was looking at the charts for different chargers on BrianG's website, I noticed that I won't be able to charge at 8 amps for my 4s2p pack... should I just charge it at the highest amps thats possible which is 7.1 amps? Does this effect the the lifetime of the battery or anything else? I heard that driving on one pack that ti will last long when you charge at less amps, and when you charge at more amps, the pack has more punch... is this true?
