hmmm,
the lrp is smaller footprint? novak Footprint 1.16” x 1.49” (29.5 x 37.8 mm) lrp 33.1mm x 37.6mm x 32mm
the lrp does not require the fan? the new Tc has it mounted already
the lrp does not have the bundle of wires? the new TC has both the fans and the cap pre-installed.
the lrp not smooth? it is the smoothest of the 2 companies speedos. it is used more int 1/12 then the gbt. this is dues to the smoothness of the speedo. it does not unsettle a 1/12 car though the corners and coming out.
I will give you this, novak has a better customer support procedure
