dcould try a align 610 or 620 both 0.08 and 8kg to 12kg, at £40 new,it just a different option from the savox 1256,which seem to be 1/8th buggy choice of the moment,i have the savox,if i had the extra £,buy buy new servos,and i agree with the views on power hd cheap and they all break pretty quickly no matter what the power rating is,but for £23 try the fubata 3305,metal geared,bb,0.19 speed and 10kg,they never broken on me yet,but you can get faster
