Just finished my mid build using the stick conversion from tcmodels and a basic mad rat.Some issues with the build on the threading of the chassis using the screws and ripping out the screw hexes so for anyone else i would pre tap the holes in the bottom of the chassis using a m3x.5mm tap first.The dots on the shell didn't match up on the chassis to the mounting pegs but the car went together very well.All in all the total cost of building a stick celled mid rat is £45 for the car,£9.99 for all ballraces including the stearing,$87 for the conversion and postage (£57) total £111.99p.Can't wait to race it (snow go away it's not fun any more)
