I'm doing my walk around testing, I thought I might list the sequence/experiences that I had. I have MatrixNav (Red, 1.7) loaded but referred to the Aileron assist document as it describes the initial set up and where the servos plug in a little better. My LED on the EM406 glows a very faint red while powered up, I would like to know if others have observed this, it still seems to operate correctly.
Firstly, I set up my 3 position flap switch (JR 2720 radio) as follows:
Position 'Norm': Flaps at 25% down
Position 'Mid': Flap at 10% up
Position "Land': Flap at 100% up
The trims on my transmitter are digital and therefore awkward to move full left or right, the flap switch works a treat.
If you power up in an electrically noisy environment i.e. next to my PC then the green LED will come on and after a few seconds the servos will go crazy. The green LED reflects a TX signal (valid or otherwise).
If you power on in a quiet environment, then green LED stays off and the servos don't move. Switching on the TX results in the green LED coming on and the servos responding correctly.
The red should flash for about a second and then go off. On GPS lock the aileron servo will move back and forth seven times and then it seems set. This takes around 30s if the GPS has been off for awhile. If the GPS does not have a lock (i.e. you are indoors), the mode switch is ineffective.
In a 'normal' mode the green LED is on and the red off, in assist mode the green is on and the red is on, in RTL mode the red flashes and the
What I did find that I cannot explain, the switches do not change the direction of the servos! I tried moving the switches while powered up and after resetting the board but the directions didn't change. I haven't tried changing the gains to a negative value.
Once, after switching off the transmitter and switching it on again, the board would not return from RTL mode! I had to reset the board to get it working again, I haven't been able to duplicate that and so I have put it down to something that I did.
Manual stick movements will still move the servos even in RTL mode. I am not sure if this is correct?
The RTL is fairly untested as I didn't walk that far and every step I took resulted in some servo jitter. I think it was behaving correctly but I will try later at the field where there is more space.
I hope the above is useful to the first timers.
