Default Eagletree stabilizer

Has anyone used an Eagletree stabilizer on a large gas powered aircraft?

No support for dual elevator and dual aileron servos. So no.

I reviewed one for Fly RC a few issues back and it worked fine, and based on the performance I'd give it a try but you'd need to accomodate the above.

It has support for one surface, aileron or elevator.
My plan is to use it for aileron and just run one of the elevators servos thru the guardian.
Only one side of the elevators would be controlled by guardian but it should be enough for stabilization.
I don't get FlyRC. Was your review using gas for power?

Nope, I ran it in a 3D Hobby Shop EBT

It was my first go with one of these and I wasn't about to offer up one of my gas planes as a test bed

I'm not sure about that idea of using one half the elevator but to be honest I hadn't thought of it like that. With a Y harness and programmable servos I might give it a go, but I don't think I'd personally do it that way.

I intend to try it when the weather clears with an 80" katana powered with a DLE 30. You can always shut it off.

bind two receivers together and then run two stablizers so you can run two aileron and elevator servos

Thats a good idea but my question is has anyone used the stabilizer with a large gas engine?

I havent tried it. I think with in a year or so we will have a A3SX or eagle tree stuff for larger 3d planes and all. They are just slowly working to bigger and bigger planes. kinda using us as test pilots

The F-16 is so unstable they have to have a computer to fly it. That way its highly maneuverable. I wonder if a model could be set up very tail heavy and have the stabilizer fly it except when you want to do aerobatics.

I bought one, I am planning to install it on a aeroworks edge 540 - 50cc... I have a emcotec 6 as power distribution to the 6 hitec 7955TG servos...
any suggestions? what to do about vibration? I had thought of installing it between the rx and the emcotec system, only problem is the dual elevator issue and the vibration!

I got this answer from Eagletree when I asked about use with big gas engines:

The Guardian should be compatible with large gas engine aircraft and is able to reject most levels of vibration. However, very strong vibrations can impact stability. To check for this issue after mounting the sensor, perform a vibration test by securing your model to a test bench or stand and ramping up the throttle slowly while watching the AHI. If the AHI begins to pitch or roll significantly during this test, remount your Guardian sensor further away from the motor, wires and any other sources of vibration or electromagnetic interference.

We hope this response has sufficiently answered your questions. If not, please do not send another email. Instead, reply to this email or login to your account for a complete archive of all your support requests and responses.

AHI means artificial horizon indicator. You need the Guardian hooked up to a computer thru the USB port to look at that.
I tested mine using an orbiter sander as the vibration driver. It drove the Guardian nuts. You definitely need to test it before you fly it.

I'm going to buy the servo programmer, that way I can link the 2 elevators in one channel,  now the only thing left is to install it and run tests.... Any suggestions on material to use for mounting and dampening ?  Any ideas welcome!   <div>Thanks</div>

If you're running programmable servos simply hook them to a Y harness, you'll have to reverse one and then you can verify with the end points and a throw meter that you have them matched up.

Vibration dampening is a tricky thing, the sensor has to stay put, if it moves around that is bad, but if the mount is so stiff that it transmits vibration, that will be bad too.

I'd go with two layers of 3m 77 outdoor mounting tape, a plywood or aluminum plate, and two more layers of tape.

I will get some tape, and see how it works... :-/
