Which castle motor?

[lambchops]

I have a converted mbx5 with a mmm, I used to have a medusa motor 2000kv which was perfect but then the magnets decided to remove themselves from the shaft and smash themselves to pieces

I went for the LRP Vortex 8 but it’s just not powerful enough despite being a 2500. Ive decided to go for the castle motor to match the speed controller but which motor would suit the car best the 2200 or the 2650? Also which would give the better run time?

Thanks
