Brushless sensored speedo

[minke]

I need a speedo for my b-max. All my 2wd cars have xcelorins which work fine, but don't cut it in my b-max. The motor has overheated several times or has slowed to a crawl for no reason. Pinion/spur changes, lipo cut off voltages, motor timing, punch settings all have no effect so I am forced to get a new speedo.

spent a lot of time looking at -

lrp sxx tc
nosram pearl evo itsc
tekin rs pro
speed passion gt2.0 and others

up to £200+ on a speedo is a big outlay for me, price differences of up to £100 between models are baffling.'Better because xxxx is more expensive' isnt a good enough reason to drop a big wedge of cash on it.

How do I choose?
