The proper mating connectors need to be soldered on the battery pack, ESC, and AXI motor. The Jeti ESC supplies the connectors for the motor but you need to select your own power connectors. My favorite connector for this level of power is the Dean's Ultra.

The stock 8-cell, 1900mAh NiCd pack weighs 16.5oz and the replacement 3-cell, 4000mAh Lithium pack weighs only 9.8oz. We dropped another 6.7oz in weight and added the voltage of two more NiCd cells.

The incredible benefit of new technology like brushless motors and Lithium power has not only increased performance but reduced the weight by an amazing 12.9oz!

I needed to slot the upper middle hole in the motor mount slightly towards the outside edge. This allowed the motor to mount easily with three M3x10mm screws. The motor mount plate was then installed back into the frame in the fuselage.
