Re: Handle on Gyros Glad to hear it. If there was anything that you think may need clarification with the sticky, let me know. Will you be coming to the scale rally in Chatham? |

Re: Handle on Gyros It's been a while since I posted, but perhaps my sticky will help: https://www.rccanada.ca/rccforum/show...highlight=Gyro Another question regards the radio system, as that will help determine if your gyro gain setting is a true representation or a generic indication. To translate that into English, I mean to say if the display from 0-100% is from one end of the sweep to the other, then 50% will show as a centered channel signal, (with the gyro gain at absolute minimum). You can confirm this by plugging in a servo to the gain channel output, (it is a standard signal, identical to any other channel). Below 50% has the gyro in RATE mode, with lower values actually increasing the gain in RATE mode. Above 50% switches the gyro to HH mode with any increase also increasing the gain in that mode. If it is a representation, then 0% gain for each mode will really be middle, (centered servo) and increasing it to 100% either direction will really only be working from the middle, (50%) to full sweep with the value maxed out. That means 0% either mode will have the gyro doing absolutely nothing. |

Re: Handle on Gyros Do not use trim. When you hover the heli and the tail still rotates adjust the tail linkage to counter act the direction it's rotating. Some cheap Gyros will never hold true. With Gyros there is a scale of 0-100. 0-50 is Rate Mode. Where you input tail movement when flying it stays there. 50 to 100 is Heading hold mode. This is where you want to be. Somewhere around 60-70. The trick is in the fine tuning. When you fly input a hard positive pitch upward. Does the tail rotate? Fly forward and make a nice banked corner. Does the tail wag? Is it Fast wag or Slow wag? Fast wag gain it too hi. Slow wag gain is too low. That's most of it in a nutshell. Check the gyro sticky link in General heli discussion for more detail. Cougar is a wizard with this stuff! |

Handle on Gyros As title says I am trying to get a handle on Gyros.So that when i build or repair a heli I can set the gyro instead of needing my buddy to set it up.Ok the reverse thing I think I have down pat. Its the gain I am having problems with .Ok most things I have read say start around 50 and adjust up or down as needed. Ok I can get it to hold at say 50 but it drifts alittle to the left at the nose. So do I add more gain or use rudder trim to remove the drift Thanks in advance |
