Flight Notes: Airplane Control Surface and SAFE Testing


UPDATED!

The first PDF document is a full explanation of the process of mounting and testing a SAFE receiver in another airplane. It includes a lot of the basic tips that have been mentioned many times in the "EFlite SAFE RX in Another Plane" thread. (https://www.rcgroups.com/forums/show....php?t=2135213)

The second PDF document is a "cheat sheet" that I made to take with me out to the field so I always had a handy reference for testing the correct movement of the control surfaces. If there's any question in my mind, the answer is on the sheet! It's a two-page document, so it can be printed on both sides of one piece of paper.

If you're not familiar with the process of installing and testing a SAFE receiver, then you should go through the full explanation. The "cheat sheet" is only meant as a quick reminder for which way the control surfaces will move based on certain actions.

If you need help with transmitter setups, see this thread in my blog.

Testing Flight Modes on the Ground


Here's how I've learned to identify the three flight modes while the plane is on the ground.

First, power up your transmitter on the correct model and then power up the plane.

Next, CAREFULLY activate SAFE by throttling up past 25% throttle (75% for Sportsman S+ SAFE+) for just a moment. You don't have to stay there for any length of time. Quickly return the throttle back to 0.

With the plane in a level flight position, go to Beginner Mode. Now roll the plane in either direction. The ailerons should move and HOLD their position in an attempt to bring the plane back to level flight. The farther you move it away from level, the farther the control surfaces should deflect.

If you switch to Intermediate Mode, the control surfaces will no longer hold their position. They'll move momentarily as AS3X reacts to the movement, but as soon as you stop moving the plane - regardless of the angle relative to level - the control surfaces will return to their center position.

Experienced Mode will react to movement the exact same way as Intermediate Mode, so we need to do another test to differentiate them.

In Intermediate Mode, roll the plane 90 degrees so that one wingtip is up in the air and the other wingtip is pointed at the floor/ground. At that angle, Intermediate Mode will ignore any aileron input from the controller that will force the plane to turn upside down. So in other words, you'll find that one direction of movement of the aileron stick on the transmitter will have no effect on the plane and do nothing.

In Experienced Mode, you can make any aileron movement that you like in this position. There are no roll or pitch limits in Experienced Mode, so the plane will react as expected to any control inputs, regardless of the position of the airplane.

Testing the Panic Button on the Ground


First, power up your transmitter on the correct model and then power up the plane.

ONLY DO THIS ON A PLANE WITH A PANIC MODE. Don't do this on the Sportsman S+, which will try to fly into the holding pattern instead!

Next, CAREFULLY activate SAFE by throttling up past 25% throttle for just a moment. You don't have to stay there for any length of time. Quickly return the throttle back to 0.

Next, change the flight mode to something other than Beginner Mode. It's very difficult to tell the difference between Beginner Mode and the Panic Mode, so you want to do this test in Intermediate or Experienced Mode.

Now, tilt the wings (roll the plane) so they're not level with the ground. The AS3X should still move the ailerons but only for an instant. AS3X reacts to acceleration, but when you stop moving the plane, AS3X will allow the control surfaces to go back to center position. With the plane tilted, press the panic button. As long as you press and hold the panic button, the receiver should take over all of the control surfaces and hold them in a direction that would return the plane to level flight. Releasing the panic button will allow the surfaces to go back to center.

If the plane acts like it's in Beginner Mode all the time regardless of how your flight mode switch is set, then it's probably stuck in Panic Mode. That's the reminder to reverse Aux1 when you have set up a fresh model on your transmitter!
