I know that there are a few diffrent all in one boards out and I know that you can go seprates. What I have not seen is a comprehensive tutorial for how and why things need to be setup the way they do

Like what is the gain on the gyro for or what does the mixer do and how do these two settings play into how the craft flys. I know that tuning is all part of it but a explination would be great. I wish my manual that came with mine had that kind of information but it is only about 8 pages of pictures showing where everything is..

I do not want specific to one type of heli info but rather info that covers the topic of correct out of the box non modified non hoped up setup..

Any takers..

"Mixer" or "proportional" trim is to set the percentage of tail motor power in relate to the main motor power. Theoretically, if you set up this percentage right, the heli should give minimum spinning in the air on zero rudder, regardless of throttle input. However, in the real world, there're other factors that constantly change the amount of power required to make the tail stay put. Example factors are crosswind, motion of the heli, speed up and slow down of headspeed, chassis vibration, etc. That's where the gyro becomes handy. It's a negative feedback system which varies tail power to counter tail spin. The gyro gain setting is to tell the system how much negative feedback (counter action on spinning tail)should be applied.

To tune in these settings, go with the "proportional" trim first. In order to do that, turn gyro gain to minimum or else it'll try to override proportional setting. With zero gyro gain, adjust proportional trim such that at stable hover, you need as little rudder and rudder trim as possible. With my Esky, I need to unplug and replug the flight battery to make each proportional trim change effective. I've heard people say forget about the mixer and just use gyro setting. This is not the way to go. First, remember gyro is a negative feedback system, meaning that it'll correct ONLY after the tail starts spining. With this strategy your tail response will not be linear. Second, high gyro gain slows down tail response. You may need almost full rudder to get the heli rotate at your desired speed.

Now you can set the gyro gain. Use just enough gyro to be comfortable flying. Often times I run zero gyro gain with my Esky Honey Bee for quick maneouvers. Other times I run 20-40% gyro. Newbies learning to hover should use 80-100% gyro. When learning to hover, newbies should keep the tail facing themselves all the time anyways.

Thanks that does help quite a bit.. I will reset and start from scratch in the morning... I was on the fence about buying a heli just for these resons the learning curve.. But my wife remined me of how I used to come home 15 years ago with a box full of sticks after being out trying to fly gliders...

Balsa is cheaper that carbon fiber so while she is right I hope my learning curve will not be as long as it was when I first got into the hobbie...

Is that a pic of you miata in your avitar... what year... what mod's

Please note that my previous post apply to rate gyro that comes with most if not all micro helis. It doesn't apply to more expensive aftermarket standalone heading-hold gyros.
