SkySeeker GT Brushless 2018 Motor Hop-Up Installation Instructions

The following items are needed.

  • Small Phillips with Magnetized Tip ( A driver with a magnetized tip makes it easier. Tip: If you have a small magnet, place it near the driver tip and it will magnetize your driver.)
  • Small Wire Cutter
  • Tape for holding the metal motor plate in position
  • Hobby Knife
  • Tape or Adhesive backed Velcro for re-mounting the receiver.

(1) Remove the Propeller and disconnect the speed controller from the receiver.

(2) Using small wire cutters, cut the cable tie securing the speed controller to the forward wing post.

(3) Apply tape to the sides of the metal plate so fix its position well.

(4) Using a small Phillips driver, remove the two motor mount screws and then remove the motor-ESC assembly.

(5) Using the hobby knife, puncture the fuselage in the recess cavity needed for threading the black cable tie as shown.

(6) Look at the mounting face of the 2018 motor. The supplied small black screws will fit in the small hole set. Insert the 2018 motor with the small hole set aligned with the holes in the fuselage. Rotate 180 if needed to position the yellow wire band bottom side. Hold the motor in position with the small holes aligned with the fuselage holes.

(7) Insert the small black screws and tighten.

(8) Thread the cable tie through the bottom slot, under the motor and then wrap back over the motor and exit through the top slot. Tighten the cable tie to firmly secure the motor to side of the molded saddle as shown. This will slightly reduce the thrust angle which is preferred for this hop-up.

(9) Insert the propeller firmly.

Propeller Balancing

Be sure to use the balanced propeller provided with the hop-up kit. Later you may use other SkySeeker GT props you may already have that are in good condition after balancing them yourself..

(10) When viewed directly over-head, the propeller spinner tip should be about halfway to the center-line of the fuselage boom or less. Press the motor case further into the fuselage side and tighten the cable tie strap as needed.

Reducing the Thrust Angle

The thrust angle is designed to offset the left-roll component induced by the propeller spin. More experienced pilots may desire to reduce the thrust angle further by wedging a spacer on the motor side that is free. A piece of the hard foam taken from the nose insert makes an effective spacer. The nose insert foam pieces must be removed anyway to make space for the LiPo battery.

(11) Attach the speed controller 3-wire cable to the receiver channel 3 as shown below for our standard FlyRite RC. Note the brown/black wires must be facing up as shown for all connections into this receiver.
(12) Mount the Velcro Backed Speed Controller as shown.

(13) Remove the foam nose inserts to make room for the LiPo Battery.

(14) Fold the short battery charge cable across the front of the battery pack with the white connector near the black and red main power wires. Placement of the charging cord in this manner facilitates battery installation next.

(15) Insert the battery wire-free end into the nose first, press it forward into the nose while pressing the wired end down firmly. The charging cable is neatly tucked as shown and the battery firmly secured.

(16) Test the motor and servo function.


Power on the transmitter and set the throttle to OFF. Make the battery power connection as shown. The cable should rest nicely over the servos with plenty of room for the canopy to close.

The motor will first chirp twice to indicate that it recognizes a 2 cell 7.4V LiPo battery. Then a two tone chirp follows to indicate the motor is armed and ready for use. WARNING: Keep hair, face and hands clear of the propeller at all times!

Move the stick and confirm the servos move smoothly. Confirm that none of the wires are wrapped around the servo pushrods. Its best to keep the wires off the pushrods. Use tape to secure them if they don't seem to stay put. If there is no response, check the receiver connections in step (11).

While holding the plane firmly, increase the throttle and confirm the propeller is pushing. If the direction is reversed, swap any two of the three motor wires.

Launch as usual, except back off on the throttle to speeds you are accustomed until you have trimmed and feel comfortable that your SkySeeker GT is performing well.

Enjoy flying your SkySeeker GT with more airtime and speed!
