Re: Gyro discussion

The 110 gyro is okay but it is miles better than the on board gyro on the CP pro. I have been setting up a Blade SR for a friend and it uses the 110 with a tail motor much the same as the CP pro. Check out the setup online. Small helicopters without a gyro are very difficult to control so please use every tool at your disposal to learn how to fly them. Collective pitch management is the hardest thing to learn so read everything you can get your hands on about it. Once you think you are good get a bigger chopper and move outside. I have nine since I started four years ago into helis and love them all but the bigger ones are much more capable.

I suspected that but it really does not seem to have any sort of holding ability at all. I bought the heli used as a "CP with some CP Pro upgrades" but the gyro was not one of them. I just googled and see that the CP documentation does refer to gyro gain adjustments. LOL - mine must be turned all the way down and I have been learning the hard way. I'll have to check the documentation and adjust mine to see if I can give my learning curve a boost.

I have the G110 gyro sitting under the xmas tree - do you think I will gain anything (besides weight) by adding it to my CP Pro? ie, is it better than the built in gyro?
Yes, the CPpro does have a gyro, and yes, you can increase its sensitivity.

But there are limitations to the degree of control you will have on this type of helicopter.

What you have to remember, fuzzydog, is that the CPpro has a motor driven tail. The tail rotor is fixed pitch. The fixed pitch tail means that the tail motor RPM is the controlling factor for tail response. That means to turn against the main rotor torque, the motor has to spin faster to create the push to move the tail. Now to turn the tail in the opposite direction WITH the torque, the motor has to slow down or even turn OFF. (I have done this many times on micro helis when trying to spin with the torque) This means the only way the tail responds in this direction is from the torque of the main rotor. Needless to say, this type of tail control system is not very good, and provides a very "mushy" tail response.

I think you mentioned in another post that you are considering moving to a larger helicopter (Ie- 450 size and up) When you do move up to helicopter with a driven tail and variable pitch tail rotor, you will be amazed at the increase in tail response.

Re: Gyro discussion

I can agree, a reversed gyro can get entertaining REALLY fast. Never knew the heli could spin like that.

Re: Gyro discussion

when you are a REALLY good hot shot pilot, you fly with the gyro reversed

(Um, before anyone gets the wrong idea that was a joke! If you have ever mistakenly tried to take off with the gyro set reversed, its sort of trying to fly a plane with the ailerons reversed but 10X worse...)

I have always wanted to try and fly one of my helis with the gyro completely off just to see how the pioneers did it. But never had the courage to bring myself to actually do it.

Other than knowing there was a gyro in the 3 in 1 I don't know anything else about them. Can't help you beyond that.

Re: Gyro discussion

When making gain adjustments using an onboard pot they normally do not take effect until the gyro is powered down and back up again. As for the one built into the 3in1 not sure if it has a remote gain capability, (where you can alter the gain using the Tx). With the remote gain signal present the onboard pot is disabled and those changes take effect immediately.

NOTE: you can enable the onboard pot by simply unplugging the remote gain lead.

Your CP Pro has a separate tail motor. There may be threads on how to integrate the separate gyro into the 3in1. Not sure if it's possible as the output is set up to control a tail servo.

There are also two modes for gyros. The RATE mode does just like the name suggests, working to maintain RATES OF ROTATION. This means the gyro will try and maintain whatever it sees at the beginning of a data frame. If the gyro is sitting completely still or spinning like a drill bit, if there is no acceleration or deceleration rate to the spin it will maintain that.

The other mode is Heading Hold, (HH), which uses the RATE data and does some math to figure out where it started and return to that point, hence the name.

If your gyro is capable of that the gain pot not only controls gain for each mode, but can switch from RATE to HH. If you look at the dial the mid point is where the modes switch and is also the 0% gain value for each mode. Anything below that 50% mid point means the gyro is in RATE mode and the further away from the mid point the higher the gain for that mode. The same applies above that 50% mid point, with the gyro now in HH mode. This is true for both the onboard pot and the remote gain signal.

On a final note, I don't remember the integrated systems, (for example 3in1) having HH mode capability until a few years ago.

it is a very long learning curve to be sure. A few times I almost gave up the hobby, figuring it wasn't for me. Then I would fly around the house a bit with the toy-grade indoor helis and get motivated to practice on the CP again. It's coming but I am wanting the assist of the gyro to do more flying - sooner.
