. Designed in the UK by Northaero technicians the X2 motor for X-class racing is a huge leap in power torque efficiency & finesse. The motor features a large 42mm x 20mm stator with N52h curved magnets this combination provides the power the 350kv takes the power management into new leagues the torque & efficiency combinations allows this motor to work on 6S to 12S batteries. The motor comes off the back of the X-ONE motor which was thoroughly tested by Fossils Stuff pilots Martin Rye & Tonstar FPV who found it to be powerful had great durability & efficiency but there was room for more power & that's where the X2 comes in. We have made it slightly lighter & changed the bearings to make the motor easier to maintain.
