I am not sure about the standard mixer GUI right now if those -100 - 0 - +100 gyro gain values apply too. The advanced GUI has -100 to 0 for normal / rate and 0 to +100 for HH. You are correct with go up until shake and then reduce 1-2% concept. Same for pitching when it does not hold anymore.
Then it will start to drift at some point at constant hover. I do not know the Walkera FBL / RX2703H-D receiver, but you should be able to reduce the tail gyro gain also. If you you can not see any difference for raising or reducing the tail gyro HH gain for your tail (starting hunting, holding, tail drifts sideways WITHOUT pitching) something is really bad. Too tight and it will cause vibrations = gyro goes crazy = drifts (I had even seen 180 tail drifts!) Some helis cause bad vibrations which will get your FBL or tail gyro crazy. There may be a wrong mechnical tail setup (over pre-comp) if it drifts to the left.įor some HH gyros you just choose the middle of the pitch slider and let the gyro work in the HH and it should hold the tail well.įor my Blade 450 with G210 MEMS gyro I choose to mechanically set the tail in rate / normal mode and then switch over to HH. With a weak tail hold the tail usually drifts to the right. The the tail hold in steady hover without drifting 45-90++ degree sideways? When you do pitching do you mean that your tail drifts 45-90 degree sideways in both directions? When you do pitching, do you have a V throttle curve? There are some ESCs which do not work well with one flat throttle value. What is the throttle value in Idle-Up / ST1 / FM1? The throttle output is the same speed always? What does "crank the throttle real fast the helicopter will rotate" mean? Please can you rephrase, add some blocks and multiple newlines? Thanks. Maybe it's just me being a non native English speaker. This is really VERY HARD to read and understand for me and probably others.

Walkera Devo RX2703H-D 2.I have the Walkera 450D03 with the RX2703H-D receiver ( I also have the same receiver in an HK 500), Devo 8 radio and deviation firmware, I've never owned head holding gyros before so I really don't know if this is a common thing or even a problem, on both helicopters I can fly them sideways as fast as they will go and the tail will hold, but from a hover if I crank the throttle real fast the helicopter will rotate, it also does the same thing in a fast decent from a hover in the opposite direction of course and only about half as severe, I didn't really think this as very odd I just thought I will increase the gain until the tale starts hunting and then back it off a little, and this is the part I find odd I've gone from the 70% gain where I started up to 100% gain, the rotation is still there on fast acceleration from a hover and I never did hit the point where the tail was over sensitive and hunting, on the older gyros I have I would just put in up mix and down mix to correct this but my understanding was that head holding gyros are supposed to eliminate this issue, I'm wondering if anyone else with this receiver has been able to increase the gain to the point where the tail is over sensitive and hunting, I'm just using the standard GUI I have downloaded and tried a file with the advanced settings with the exact same results.
