Is this Blake?? Just making sure....the 720's AND 760's don't usually run hot - I don't know why you would say that? My 720 was one of the best duner motors I ever had....for that matter, the 760 I have now was an awesome duner - has been extremely reliable through some serious dune pounding and a number of hard races alread - and it didn't run hot (unless you want to call 170 degrees all day, in 90 degree temps hot!).......
Making blanket statements about a motor kit can be misread and misinterpreted by many - and that is unfortunate.....
Joey - your 720 will be awesome. One of my favorite motors ever..........
