Hi Tony

Too cool, I hope you like I’m really enjoying mine. Make sure you check out the section on direct rate and servo limits if you’re using 3d mode to stabilize with or without heading hold.

Effectively gives you a gyro with stick fade out when you move the sticks without having to program a mix on the gain to make that happen.

Ill explain what I mean and if you already know please disregard.

1. In a normal rate gyro when you move the stick the gyro will react and try to correct the movement you’re trying to input by giving a opposite control input reducing your control surface output you would normally have at that stick deflection. Some of us have called that the feeling of fighting the gyro.

2. To overcome this issue you can have a dual rate with a higher rate, or if your gyro has a R/C gain adjustment you can create a mix that greatly reduces the gain just off the center of your stick movement. Generally only high end computer radios are capable of these types of mixes.

3. Or you can buy some of the higher end Gyros like the ACT fuzzy pro, or The Power box IGyro that have this feature built in.

4. The Guardian takes a slightly different approach, direct rate looks at the % of your stick movement then tries to roll, pitch, and or yaw your aircraft at that % of the guardians set rate. (Programmable as rotations per second using the computer interface default is 1 per second)

As long as you hold full roll stick it will command full roll in the ailerons in an attempt to reach 1 roll per second. If your plane cannot achieve this it will go to full deflection trying to till you release stick. If your plane is able to do more it will back off the ailerons somewhat and maintain 1 roll per second.

What you will feel is a plane that is flying with no restriction on its controls however is stabilized even during maneuvering. However this is where we can run into some potential issues. The Guardian can drive the servos pretty far and if your aircraft cannot take the full throw of the servo you could easily have damage caused by the servos overthrowing trying to maneuver the aircraft to its programed limit.

This is where servo limits come in. If you have a servo millisecond reader EMS Jomar makes one if you don’t (http://www.emsjomar.com/SearchResult.aspx?CategoryID=6).
Measure the pulse width in milliseconds for full up and full down for your control surfaces. You can then set the limits for the servos in the guardian so it won’t be able to over throw your surfaces and possibly damage something.

Sorry for the long explanation, hope it helps. Let me know if you need anything clarified.
