Hi

What speedo would you recomened for stock 27t motors ( hpi 27t) , i know its only a cheap motor , soo you cant exspect much !! its for use in our stock mini class at our local club
im currently using a nosram stock spec , which is getting a bit problematic !!
ive been offered a gm genius 90 and a tekin rs , my mate is using a cs rocket and his car always seems quick , but these are getting rare and hard to find ..
what would you chose ?
