In the real world, two aircraft of the same design may fly differently because they are set up differently. This is also true in the simulator world.

We have calculated all the aerodynamic parameters of each of our models to make them fly like the real-world model. But you may still adjust the control surface throws, weight and CG of your simulator model to make it fly more to your preference.

Reflex has made this very easy with the "Modify Model Parameters" section. Pressing F5 while in simulation will bring up this section enabling you to adjust the flying characteristics of your model.

Parameters include:

• Aileron efficiency - controls the amount of throw of your ailerons
• Elevator efficiency - controls the amount of throw of your elevator
• Lift performance - controls the thrust to weight ratio ( NOT the airfoil's lift)
• Rudder efficiency - controls the amount of throw of your rudder
• Expo elevator, Expo aileron, Expo Rudder - control the amount of throw towards the center of your stick for its given control surface. Negative values in percentage gives less throw towards the center position of the stick and more throw as the stick moves to its max range. A positive value gives more throw towards the center.

The only other parameters you may wish to change are the model's weight and CG. We base our Reflex models on the average weight of the airplane we are modeling, but your real-world plane may be lighter or heavier. You may prefer the "feel" of your aircraft in Reflex with your model's true weight applied. We also place our models' center of gravity in the neutrally balanced location. However, you may prefer the "feel" of a more nose or tail heavy aircraft. By pressing F11 while in the simulation, Reflex will open the "Physical Parameters" dialog. This is where all of the model's measurements and aerodynamic parameters are placed.

Weight:
In the "General" tab of the physical parameters dialog, adjust the "Model Weight" parameter to more closely match your real-world aircraft's weight.

Center of Gravity:
In the "General" tab of the physical parameters dialog, adjust the "Distance of CG behind profile nose" parameter. This is the distance of the CG behind the leading edge of the wing (note: this is NOT the distance of the CG behind the nose of the plane). This parameter should be changed in very small increments; choose smaller numbers for more nose heavy performance, or larger numbers for more tail heavy performance.

Note that the other measurements in the "Physical Parameters" tab are all measured and calculated from the real planes they are modeled after and should never need adjusting. However, you may decide to experiment and change various parameters. You should always backup your models before altering them. If after making changes, you want to return to the original configuration but can't remember the original settings, simply restore your model from the backup or re-install the model from the W3 installer. If you have misplaced your installer, remember that you can find your original plane on our web site. It will be in your hangar available for download anytime at no charge!
