Thanks for the replies guys. So from reading here, the D3.5 21.5 is still highly competitive against the likes of D4 and Killshot 21.5's?

Also i'm looking at the BIG BLUE D3.5 21.5 for 1/10 TC on Asphalt. Is this ROAR legal? Not too worried about it since they only really care about the turn of the motor at my local track (couple others running D3.5's too) but I thought i'd ask anyway.

Does anyone know what rotor comes with it stock? Since it doesn't say MAXZILLA i'm assuming that it just has a standard 12.3mm rotor? Would it be a good idea to buy a 12.5mm rotor aswell? I run on a 130ft by 65ft fairly flowing low/med grip asphalt track. Also in Australia we can get quite high ambient temps, up to about 35-40 degrees C
