Ohh and TC3's make good drifters.
Also forgot to mention that a locking up your rear diff really helps a lot as well.
I used an old inner tube from me MTB and removed the bearings on my TC3, but others have used everything from bluetack to hot glue.
One of the guys from another RC drifting forum recommended the Traxxis friction pegs though.
So i used these on me Cyclone.
I found these a lot better as i'm able to adjust very finely the amount of lock up, plus they're very smooth.
If i just tightened my bearings to the same amount of lock the diff felt very notchy.
So my advice would be.
1/ Sell the Gyro
2/ Order some HPI T-Drifts with the money you made off it
3/ Lock up the rear diff
4/ If you really feel like getting the most out of your chassis, order some drift springs and carry out the shock adjustments i suggested above.
Hope that helps.
Cheers
