The painting, details, and markings on this F-8 are excellent.


After the elevator pushrods are installed in the control horns, glue the black carbon- fiber pushrod guide to the underside of the stabilizers. These guides keep the long pushrod from bowing when the aircraft is in flight, so it is critical to have them securely glued.


There is plenty of space inside the fuselage for the receiver and LiPo battery. The airplane is advertised to accept a 3S 1,000 mAh to 2,200 mAh LiPo battery. I would suggest one in the 1,500 mAh to 1,600 mAh range to keep the weight down, provide reasonable flight times, and not overstress the battery. It will tend to be placed toward the back of the battery bay, so take this into consideration when you install the receiver. Setting up the radio is


easy. Because the Crusader has two servos, you will need to set up your radio as a flying wing. Some radios refer to this as an elevon or delta mix. If you are unsure, the airplane’s manual illustrates how the control surfaces are to move with various transmitter stick positions.


Before flying, check the


center of gravity and set it according to the manual, approximately 125 mm from where the wing meets the fuselage. This is slightly in front of the servo control horns. Set the control throws to the low rates setting at 21 mm up and 21 mm down on the elevators, and 11 mm up and 11 mm down on the ailerons for your first few flights.


Finally, test the power system before your first flight. Run the throttle at full power for approximately 20 seconds to make sure everything is working correctly. This EDF

unit puts out approximately 300 to 330 watts, so a weak battery (especially if it is less than a 1,500 mAh capacity) might sag voltage and hit the low-voltage cutoff shortly after launch and cause a crash. By testing it for 20 seconds, you know the battery will hold voltage and not shut down immediately after launching. Top off the battery’s charge before you head out to fly.


Launching the Crusader


is straightforward, especially if you read my Spring 2018 column about hand- launching EDFs. Spool the


fan up to full throttle then firmly throw the aircraft straight ahead. After the model is released, let it accelerate and build up speed for approximately 5 to 10 seconds then reduce the throttle and begin trimming it out. You will find this to be a pleasant-flying aircraft with no bad tendencies. For those who are too scared to hand- launch or want to perform touch-and-gos, MotionRC sells an optional set of landing gear with a steerable nose wheel for this airplane. Enjoy your F-8 Crusader!


Small in size, but large in performance and fun, the Freewing F-8 Crusader is great for grab-and-go park flying.
