I tried looking on the net for a .26 head for that motor but I can't find anything. Only thing I'm finding is complete RTR buggies or full motors. I dont see why another .26 heat sink wouldn't work on that motor though. Is it possible to look up a .26 heat sink and get specs then measure your head to see if it'll fit? At this point I think it's the safest bet. Unless you buy another motor. At least that way you'll have a back up when this one finally goes. There's a plus. Happy Hunting
