Mount the Canopy ❏ 1. Cut the canopy to fit the fuselage. The canopy can be held in place with epoxy or small wood screws. ❏ 2. If you would like to add a tailskid to your Flite
Streak this can be done with a wood or sheet metal screw or with a nylon tailskid. The photo shows a Great Planes Wing Tip Skid (GPMQ4445).
PREPARE THE MODEL FOR FLYING Set the Control Throws Use a Great Planes AccuThrow (or a ruler) to accurately measure and set the control throw of the elevator as indicated in the chart that follows. To increase the control surface throw, move the pushrod to a hole that is closer-in on the control horn on the control surface, or move the pushrod to a hole that is farther out on the bellcrank. To decrease the control surface throw, do the opposite.
Balance the Model (C.G.) The C.G. (center of gravity) must be checked when the model is ready to fly. All components should be installed with the fuel tank empty. ❏ 1. Use a felt-tip pen or narrow strips of tape to
mark the balance point on the bottom of the wing
3-1/4” [82.6mm] from the leading edge of the wing on both sides of the fuselage.
❏ 2. Lift the model, right side up, at the balance point you marked on the bottom of the wing. We use the
Great Planes CG Machine™. If the nose drops the model is nose-heavy and you must add weight to the tail. If the tail drops, the model is tail-heavy and you must add weight to the nose. ❏ 3. If additional weight is required to balance the
model, use small pieces of Great Planes stick-on weight (GPMQ4485). Our prototype model required one ounce of weight on the tail.
❏ 4. After placing weight on the model where
necessary, recheck the C.G. to confirm that it is correct.
❏ 5. Attach the weight with screws or glue securely in place. Identify Your Model No matter if you fly at an AMA sanctioned club site or if you fly somewhere on your own, you should always have your name, address, telephone number and AMA number on or inside your model. It is required at all AMA club flying sites and AMA sanctioned flying events. Fill out one of the identification tags on page 11 and place it on or inside your model. Ground Inspection Before you fly you should perform one last overall inspection to make sure the model is truly ready to fly and that you haven’t overlooked anything. If you are not thoroughly familiar with the operation of control line models, ask an experienced modeler to perform the inspection. Make certain the elevator is secure, the pushrod is connected, the elevator responds in the correct direction and the C.G. is correct.
IMPORTANT: More than any other factor, the C.G. (balance point) can have the greatest effect
on how the model flies, and may determine whether or not your first flight will be successful. If you value this model, DO NOT OVERLOOK THIS IMPORTANT PROCEDURE. A model that is not properly balanced will be unstable and possibly unable to fly correctly.
Set up the Flite Streak so it has the following control surface throw: ELEVATOR: 3/8” [10mm] up and down Set the elevator throw as close to this setting as possible. If you have too much control throw the model may respond too quickly. If you do not have enough throw, you may not be able to maneuver the model or have enough control to land it.
