I have been running a TA05 IFS at my local club for the last few meetings with no probs. All I upgraded was to alloy front hubs, front UJ`s, TRF shocks and alloy motor mount. I run LIPO and 13.5 Brushless and with kit set up and Sorex 24r tyres it runs great out of the box with very little tweaking. I have also just bought a TA05R which has been upgraded to IFS, they are both great cars and handle really good straight from the box, Ive had no breakages which is great for a car with quite a low price tag.
