alright i have read well over 50 threads now about locking the diff/etc. I dont understand any of this about the spool, having the front one done, or nething to do with the diff that will be best for drifting? can som1 please explain in very much detail everything to do with locking the diff. i know this sounds like a lot but i really want to understand the goal and the purpose/ ways of doing this. my tt-01 comes in this week and i want to know how to do this while im building it. ne help will greatly b appreciated. thanx.

srry for the double post but i just read a thread and i understand what locking the diff does... but now what will work better locking the diff or using a spool? and what does a spool do cuz i still dont know what that does?

and btw the TT-01 has gear diffscorrect, what will be the easiest way to lock those diffs?

btw this is the car that i bought...

can anyone give me a picture tutorial of locking the diff in a TT-01(like the one above)(i am a visual person to understand)?

A spool is just a solid diff. It applies power evenly to each tire via the dogbones/CVDs. Here is a spool (They are also sometimes called straight axles): http://www2.towerhobbies.com/cgi-bin...&I=LXDGD6&P=ML You can see where the dogbones go into the ends of the spool. The gear goes on the spool and is where the shaft gear goes to spin the spool, which in turn spins the tires.

Here is a normal diff: http://www2.towerhobbies.com/cgi-bin...?&I=LXJHM9&P=7 This is limited slip. It supplies power to the tire with less traction.


Off topic, but I locked the diffs in my TXT-1 because I use it as a rock crawler. This is fine because I want max power to all the wheels all the time, plus, I am never really going full throttle and I am also not on a high traction surface, like concrete or carpet. High traction surfaces can add stress on your drivetrain. When locking a diff or installing a spool, you lose turn radius, however, doing it to a drifter is fine because you are trying to break traction. You also almost always install PVC/ABS drift tires and don't have to worry about putting added stress to your drivetrain. I hope this helps.

alright..thanx.. 2 more questions...

1)what is a rolling chassis? (i heard som1 saying they wanted that)
2)is the ball bearings a hop up for the wheels? or what r they for?

1) a built up kit without radio gear/cells/motor/ESC
2) An RTR kit usually has bronze or plastic wheel bearings whereas more top end kits have bearings as standard and are ALWAYS the #1 hopup for ANY r/c car

Ballrace bearings are near frictionless and can last the life of a car if looked after
