Need some quick help, whats the difference between the castle mamba max pro, mamba max sct, mamba max monster, mamba micro? other than the obvious like the "SCT" would normally go into a short course truck, etc. i guess my main question could i use a mamba max pro sct or monster in a 1/10 off road buggy?

Yes you can.you would probably be better off with the sct than the monster. Better option would be a hobbywing xr10.
