What gyro has the most amount of gain on the market today?

That's not a figure that can necessarily be compared from one brand to another. One product may hold at 70% comparably to another at 2/3 or less of that figure.

Purely in terms of the number, the GY701 works best at some of the highest figures seen in gyros today.

try longer Tail Blades, or wider Blades

I am using this gyro on a Harrier, do I need anything other than the gyro to get all the gain out of it or is there some programing that I need to do?

Yeah, you need to tell us exactly how you're using it. What axis, servo, to what the servo is hooked, etc.

I am just looking for a gyro that gives the most amount of servo travel for the least amount of movement on the gyro. My puffer jet system needs to keep the aircraft within a few degrees or its over. The gyro I am using now is the Futaba 2 axis and I need almost ten times the amount of throw out of it, it does work but just barely, plus the servo arms are so long the resolution is out the window. I think this gyro has the last amount of gain due to it being for aircraft use. I have asked Futaba if they could do anything about it but they can't be bothered with it.

It sounds quite strange what you are doing, servo gain does not really equate to servo travel.

Perhaps you need to make your own with a PID control or something like that.

Only thing i can recommend is a strong servo with a long strong arm.

By adjusting the gain up does that not mean more servo travel?

Unfortunately I don't know anything about PID's It is probably what I need to do, does anyone here know someone that does this type of work?

raise your ATV and/or use a longer Servo Arm

I'm already using servo arms that are almost 3 inches long on micro servos, plus there is a amplifier in line that doubles the out put of the signal to the servo, and this just barely works

Gyro gain has nothing to do with the travel limits of a servo plugged into it. Gyro gain only regulates how sensitive the gyro is to rotational forces.

What you need, as helicraze says, is a good strong servo with loads of torque and a long servo arm so smaller movements on the drive cog equate to a large movement of arc from the servo arm. This is heighening mechanical gain for the gyro rather than electronic. You can also adjust the travel endpoints on your radio to really wring it out. The servo you use will need to have good resolution to handle a three-inch servo arm, as you say. Other than the servo arm we've no idea how large the application is, but among fast, strong lightweight tail servos the Futaba BLS251 is a very good choice IMHO.

I hope that helps and good luck on the project.

You may need a faster servo. Most micro servos are not fast enough for gyro use. Even if you turn up the gain, the servo might not travel fast enough to have effective control. A good mini servo may be the key

All these heli guys and the airplane guy is on the right track

The electronic gain has nothing to do with the acutal gyro sensitivity (though thats how it appears in the end result). It's how much servo response you get from the gyro for a given rotation. More gain = more servo response. Thats why you get wag when the gain is too high.

Someone needs to hook you up with Angelos from Spartan, I would think he could probably help you.

I ran my Mini-G at 100% gain on an 8900G and still never got any wagging, the tail was very locked in.

Sounds like you need more mechanical throw than gyro gain. Use a bellcrank system to multiply the servo throw.

Sounds like you don't know what you are talking about, I talked to the guys at CYE and they said its common to run 100% gain on the Mini G on a Trex 700.

My post was directed to the OP, not you (otherwise I would have quoted YOUR post; like I did here). Carry on.
