Not a silly question at all. If the ship wants to go somewhere else while the PH or RTH is ON and good GPS signal, its usually due to bad trim settings for the auto-leveling (AL). When the GPS functions are activated the Auto-Leveling feature is activated as well. If the AL is not trimmed properly the GPS will fight it. Lets say for example the AL trim on your ship is slightly off to the right. As soon as AL is activated it will bank right and begin moving. When PH is on it tells the ship to stay put but the AL will say bank right. The GPS will see this and try to correct but if the trim is too far off, the trim will win the battle and you'll have a runaway ship. Follow this procedure: On calm wind day (zero wind) bring the ship to a hover. Activate AL. Observe its trim. Is it trying to move in a certain direction when you activate AL? Keep AL ON and adjust the trim until the ship is stationary. Leave AL ON and land the ship. Disarm. Unplug the HFP battery. Turn off AL on your Tx. Plug in the battery to the HFP. Rearm and bring it to a hover. Activate AL. It should stay in one place. If you trim even with a light breeze it will always think there is a light breeze, drift when there is no wind and fight the GPS. Do not adjust the trim on your RC tx after its set. Also make sure the AL gain is turned up high enough just below the oscillation point. Keep the questions coming. I've had the same questions and many more till I got it nailed.Ok, next silly question...
I have the same firmware running on the GPS and the HFP board. I have been able to do the temperature, accelerometer and temperature calibrations successfully.
I have been able to do the compass calibration successfully outside and the correct checkboxes work at the right time in the main tab, eg: AH, AL, PH, RTH. On the GPS tab the map comes up successfully and the satelittes show a number of satillites connected. The compass calibration box is checked as is the GPS connection.
When outside I get a blue led on the GPS board and can take off an fly.
However when I took the X8 to the flying field I couldnt see any reaction to the PH being enabled and when I flew the X8 away and tried RTH nothing happened.
My AL and AH were working well.
I will be doing something daft but at this point all the indicators are telling me the GPS board is calibrated and set up correctly and responding on the setup software to the switch inputs but out in the field there appears to be no GPS functions when flying.
