Altitude Hold Parameter Adjustments
I just came in from a short test over the driveway as I made some changes to the altitude hold settings.
It seemed to make an improvement. Conditions: very light wind, 5 degrees C outside. I have added my own version of a simple 2 axis gimbal camera mount for HK wingcam bringing all up weight to just over 1,000g flying weight, 9 chnl Orange RX with satellite, 2650 ma Nano-Tech. min Gas default 350, raised to 375 max Gas default 700, reduced to 675 At about 75 ft and in a stable hover in Balance mode, switched to Altitude hold and it just sat in space without a lot of auto throttle changes. It was much steadier better than before. I did try min Gas 400 max Gas 650, earlier, but it seemed to hunt even more so I think the numbers have to have a certain range between min and max. Of course that will also depend on your overall flying weight as I expect as you load on the weight it will take more power to hold a steady hover, so your min and max would have to go up to compensate for the additional weight. I still can't figure out how to give the controller a bit more "forward" when in Balance mode as even adding forward trim, the quad still seems to want to back up a lot. I want to hold a position even in some wind, but it seems I have to hold a lot of forward stick. The FC is fighting my input. Any ideas? |

We are ALL waiting to hear from idea-fly on what that 4pin ULINK connector is for "compa71" but for some reason they don't want to let us in on the big secret.
Sundayflyer32 I think the altitude hold min and max gas is just the neutral range for the throttle position....Meaning it wont try to climb or descend in that stick range. It doesn't change the sensitivity of the barometer. Also If you want more forward control make sure you don't have your dual rates on and move the pitch and roll slider to the right in idea-fly tools under control strength. |

Remember to balance your quad in both axis(front to back and side to side) you can do this by following these easy steps.
-- remove canopy --install your battery --grab a pen or small screwdriver in each hand --place them in the center,and on either side, of the quad and lift --watch for which way it tends to lean and reposition your battery accordingly Repeat for the other axis. Also very important to make sure NO wires or anything is touching the flight controller box thats in the center of the quad..... you don't want to transfer vibration to the FC. Happy quading!! This thing is a blast! |

Hello all. Been lurking for a several weeks. I got my quad and cam last week and finally getting to. Love the quad and the camera and this support thread.
Heres some video...
As you can see I am a novice pilot. I am glad this thing is tough. Thanks, Hankinator |

~LoL~ You seem to be very knowledgeable on this.. already Im having problems with my 4-S.. can't get past the setup part because there are things I apparently didn't receive in my package, and other things I have no idea what to do with.. For a good laugh, go check out my posts in the other 4-S thread.. |

Ready for FPV!!
![]() Successfully swapped my FF9 (35MHz) transmitter from mode 1 to 2, and attached my FPV cam to the front of the quad using DS tape and a tie wrap with some firm foam supporting the lens housing of my camera. Added another ply board to mount the cam onto, and an extended ply board to carry the EZOSD and current sensor at the tail end, the Vtx is mounted with DS tape and a tie wrap at the side of the centre section of the frame. Not sure what to do with the long rx wire from my radio rx..Any ideas please? Just don't want to compromise range, but nor do I want it getting tangled in the rotors! ![]() Last job to do now is setup the EZ Antenna Tracker to drive the pan and tilt on the groundstation to move the 8dbi panel antenna around (I think that's going to be the hardest part) Balanced the whole machine longtitudinally and laterally, the EZOSD (weight at the rear) has done the trick in keeping the CG correct. ![]() Here's a few pics of progress. Mavrik, did you ever get a video of your FPV flights? I swapped the wires in the rx as you suggested and now can use my 3 pos switch, so thanks for the tip. Anyone else done FPV on this yet? |
