My Posts This: Topic Forum | Very nice.
A few hints:
1. you mention "adjust the endpoint of appropriate channel in your Tx as necessary to achieve 100%"... you should also mention the value 1600 because in the expert mode, in live screen, you work with absolute values, not %.
2. You should say why people should adjust the tail between 50 and 60 or so. There are some servos that will go powerless on the value of 64 on side A (and sometimes even lower) so the user should double check he has power at the extremes
3. You need to mention that people have to check if tail compensation is working the correct way. On a clockwise rotating head the tail wants to naturally go counter clockwise to the tail compensation has to be correcting clockwise. With the latest "I" theory that MrMel has posted, this might be avoidable since you don't rely on tail compensation anymore but until V4 comes out, I would always want to set it correctly.
4. You should explain better the flight trim part. you need to trim the heli in a hover, in a full climbout and in a full descent (or inverted climbout) so that you can adjust the swash at center, top and bottom. One should also look out for phasing issues. There are two techniques for that.
a) from a hover (tail in), give full collective and enough down elevator as if you where taking off in a drag race. If the heli shoots to the left, you need to adjust the phasing in the swash menu counter clockwise. If its to the right, you adjust clockwise.
b) from a hover (tail in), do a half forward flip. If the tail gets out of the axis (not exactily in line with you anymore) than phasing is off. if the tail is pointing to the far left, you need to rotate the swash layout counterclockwise, if its to the far right, you need to rotate it clockwise. Always start by one degree at each time to get it perfect.
5. You should mention that the sensor has to be perfectly square with the longitudinal axis of the heli although the cable can be pointing to the rear or to the front.
6. Don't forget to mention tail piruette optimization to get the vstabi to correct while piroetting.
7. It is important to set cyclic gain in the cyclic menu (bottom left) to 109 when you activate geometry correction. Someone screwed up and geometry only gets perfect when that value is 109. Not lower, not higher.
For now, I think thats all.
PSI,Bell and Hiller should be mentioned but I'm lazy right now. I'll post something tomorrow.
