Same rules apply when choosing a suitable medusa- they are just like neus, and same size as the feigaos with regards to L can and XL can sizes etc. I would say a 2000kv 60mm medusa was fine for 14 nimh cells, or 4s lipo if you make the leap one day. A 70mm 2000kv version would be even better, but I dont fancy your chances with nimh cells, they will run very hot with a more powerful motor...
