I picked up a 60amp ESC today and I mounted it in the rear of the Typhoon to help get this thing balanced. I checked the CG with 2200mah 20c battery all the way up front and the CG was at about 170mm. I figure with the 3300mah 25C battery I ordered from EJF I will have to move it back a bit. I am happy with how it is balancing out I just hope it's not to heavy. I picked up a lite weight wheel for the front LG which is bigger then the stock one so it lifts the nose up nicely for take offs.
