TRF201XR help

[D-StyleNZL]

Im having a battle trying to drive my TRF201XR.
The Rear end seems to be on ice, the slightest throttle and it breaks loose. Even the Cheap RTR's seem to go better.

Track is low-grip/dusty.
Tires are PL Hotshots, which is the tire of choice at my track

I havnt been able to find a base setting for the XR to start from, either its for the Old trf201 or all you lucky ones with XM/XMW's on high grip tracks.

Any help would be great.
