    Will a helicopter Gyro work?

    Will a helicopter gryo hooked up the throttle channel help the REVO jump flatter? If it noses up, it should cut the throttle, and if it noses down, it should increase the throttle...

    Plus, it should help with wheelie control. When it wheelies,the gyro will cut power so that it stays flat.

    Has anybody tried it? Will it work?

    I don't know if it will work, but it sure sounds like it is worth a try.

    It sounds reasonable...but wouldn't you need a pretty big gyro for the weight of the truck?
    what was that? what was what..oh that. thats mine.

    Don't think it's going to do what you want on the throttle channel...

    Gyro's are normally used for steering to help maintain an even heading when you're not giving any input. They will try to maintain whatever attitude the gyro was at the last time you go to neutral on that channel. This is alright for steering, but on throttle it could be problematic.

    Gyro's can also have some "flutter" which may make the throttle act very strange and possibly dangerous. Example, you pull a wheelie and let off the throttle, nose comes down, gyro applies throttle trying to get the nose back up.

    An RC gyro is fairly small and connects in between the servo/esc you want heading control on and the RX. Definitely a case of size doesn't matter here.

    I can't comment on a gyro leveling a revo in the air, but I came up with a different method to prevent wheelies. I actually ended up making a circuit which limits the rate at which the throttle is applied (without limiting top speed). The circuit goes between the receiver and the ESC. The rate is adjustable via the 3rd channel of my radio. I can adjust anywhere from instant power to very slow acceleration on the fly from my transmitter. You can mash the throttle and the little revo will accelerate nice and smooth all the way to top speed.

    Very cool. Sounds a LOT like how the MMM implements punch control (basically integrating it over time), except this circuit is adjustable via CH3.

    Does anyone besides me have any experience with a gyro on any form of RC? [Heli's, drift and drag cars here]

    I stand behind my statement that using one on the throttle is a VERY BAD IDEA.

    Yeah... bad idea on throttle, i was thinking steering.
    I have flown planes with gyros and now that I think of how they work it wouldnt work good.
    If you do a wheelie your front end will go towards the ground and it will give more throttle to keep your front end up... Yeah, bad idea.

    Turn the gyro around so that it would be oriented in the right direction..

    Does any one have a Gyro that is willing to try this expierament? I hate to buy a gyro just to try when i could be buying replacement parts and what not...

    Doesn't matter how it's oriented, whatever attitude the truck is in when you go to neutral, the gyro is going to give strong output to make a correction trying to maintain that attitude. If you purposely reverse the gyro, then it will be even more aggressive, and then you'll see something like hitting the brakes hard, but not stopping, then when you go to neutral on the trigger, the gyro tries to get the nose back down, but since it's reversed it applies more and more throttle trying to reach that attitude. You could dial down the sensitivity, but to get rid of the surging nature of a gyro's output, it would be off or nearly off anyway.

    Please people, as someone who's been cut up by a helicopter with a berserk gyro, PLEASE DO NOT TRY THIS!

    I promise one thing, if someone puts a gyro on the throttle channel of an ERBE, you WILL be buying plenty of replacement parts, the gyro's cost would be the least of your worries.

    This idea is dangerous to yourself and those around you, especially if you have no previous gyro experience. If you want to play with a heading lock gyro, put it on the steering like it was intended to be.

    Gyro's of the piezzo type can be gotten for cheap off of eBay or any of the internet outlets for the chinese stuff. That being said, I second 1stGenCRXer's opinion that this is a bad idea. I know how they work and have seen them work in my heli. I can't say for sure how it will react or how bad an idea it is, but it's definately not a good one. Please don't.

    On a heli, they keep the tail in check. On a drifter, they help you power slide. On the throttle, your truck is going to go nuts.

    I do helis and I would say 99.9% that it will not work on a throttle channel. It would work for steering on a speed run.
    I make tap adapters and power harnesses.

    I've used gyro's for going fast in TC's but never thought of using them for this.
    i'm not sure how it would work.
