Power Systems assembly

Motor Installation

1. There two types of mounting holes on the head plate of fuselage, can be selected according to motor specifications.

2. Put the screws into motor mounts and put aluminum columns to the other side of the screws.

ESC Installation

1. Attach the connected ESC to ESC holder with double-sided tape and Secure with cable ties.
2. Tie the wires of ESC and motor with fastening strap. Please take note that the battery elimination circuit of ESC could be 5V, 6V, 7.4V ,because some customers’ receiver equipment does not support high voltage, so the factory default set is 6V, if you receiver support high voltage (2s,8.4V), then we suggest that you set the bec to 7.4v, so that servo power will be more strong and the speed will be more fast. The switch is on the back of ESC (no sticker side) .

5. After determining the gap, stick the masking tapes to the canopy, use a drill or a utility knife to bore a hole according to the marked fixing holes.

6. Use a small size of Phillips screwdriver to tighten the T2x 8mm self-tapping screws along with washers to the cowl, tear off the masking tapes when a half part of the screws be twisted into the cowl, then continue to tighten the screws.
