F-22 Raptor, making it suitable for use as a trainer aircraft. Without the droops, your F-22 Raptor ARF will be an all- out jet-like fighter. Have an instructor nearby for the first few flights. Without the droops, the F-22 Raptor ARF will descend more quickly and land faster like a sport model.
Note: Align the aileron with the wing tip as shown if you are not installing the NACA droops on your F-22 Raptor. Make sure the aileron servo leads are connected as described in the previous section. Center the aileron trim on the transmitter.

Rudder The final control surface direction to check is the rudder. With the radio system on, move the rudder stick to the right, this will make the plane turn right. The rudders should deflect to the right as well. If not, check the radio instructions on how to reverse the direction electronically at the transmitter.
The following photos show how to measure the control rates with the throws listed for the low rates for your (38mm) F-22 Raptor. The control throws for your F-22 Raptor are as follows: (38mm) Aileron Rate: 3/16-inch (4.75mm) up and down Note: Measure the aileron throw at the wing tip.
Section 14: Adjusting the Throttle With the radio system on, move the trim lever and throttle lever towards the bottom of the transmitter. Look into the carburetor to check that the barrel is closed. If the throttle is not operating as described, you may need to change the Travel Adjustment setting in the radio.
Section 15: Balancing Your F-22 Raptor Balanced Correctly In order for your F-22 Raptor ARF to fly correctly, you will need to check the balance of the plane with the fuel tank empty. This is done by supporting the aircraft either using your fingers or by using a balancing stand.
Page 51
F-22 Raptor ARF may not be balanced properly. Weights can be added to either the tail or the nose of your F-22 Raptor ARF if it does not balance properly. Stick-on weights available at your local hobby store are the easiest to use, and come in sizes that are easily placed on your plane.
Flight preparations are the items you must check each Range Check the Radio time you travel to the flying field. Because the F-22 Raptor A range check should be part of the preflight process ARF will encounter a variety of situations, it is best to keep as well.
