you are right about the setting on the gyro. i did not catch the part that you are running a digital servo. i do not have a digital servo for my tail. when i was setting up the gyro i talked with a person about how it should be set. if i remamber right, he told me that with a digital servo you want to turn the gains all the way up or off. i could be full of sh_t on this one. maybe there is someone that will read this post and get it straight, then we will both lean something.

The Hawk is flying very well.....

Thanks to Alan (Big Al's Hobby Supply) and Dan Willis, for the help this afternoon. We got the Hawk flying like a champ.

I had multiple problems, but we worked them all out. Even got it set up in stunt modes, all head speeds set, tail adjusted and it fly's like a dream.

These heli's are all in setup. A beginner (newbie) like myself, setting one up is a problem all on it's own, but you learn from your mistakes and usually make huge leaps in knowledge.

Again, thanks to this forum and heli freak.com for all the help, but you can't beat the hands on training of a local experienced pilot !

Cheers,
Rob

Channel 5

I do not have end point adjustments or dual rates on channel 5 which is called the landing gear switch on the 6VH system. The system is not digital either. The options on the panel are to reverse channel 5 or turn it on to be used for sensitivity gyros.

PAHelipilot,

If you can't adjust the end points on channel 5, the only thing I can say is the radio is not suitable for use with the 401 gyro. Basically, your radio is telling the gyro to be at 100% gain all the time.

At this point I believe you have two options, and both involve spending some money. You can either buy a lessor gyro, like the Futaba 240, which has a manual gain adjustment on the gyro, or you can buy a better radio. It is mandatory that the radio be able to set both the flight modes and the gain on the 401 gyro. Maybe if your radio is new you can take it back where you bought it, explain the situation, and trade up to a radio that will do what you need.

The government cannot give you anything without first taking it from someone else.

Normal Mode

Can't I just leave the switch for channel 5 in the normal mode and use the gyro as a non heading hold? The instructions for the gyro mentions that this can be done.

I "think" you may be able to do thay by disconnecting the channel 5 input to the gyro. Anytime the gyro sees that pulse, it is being directed to the paticular mode, and GAIN determined by the percentage of throw of the retract channel. The excessive gain is what is causing your helis tail to oscillate.

My Options

Well I guess my only option is to try to use the gyro on the normal setting or try to find another radio system. I'm not in the market to buy another complete system, maybe I can find another transmitter somewhere that gives me some more features. I would really like to utilize the option of the heading lock gyro.

Thanks again for all your help.

PAHelipilot,

I just went to the Futaba site and checked on your radio. Now that I see it, I have worked with them before, and it is the most basic of heli radios, but the site said the 6vh does have ATV's. Doulble check under the front plastic control panel cover and see if there aren't pots to set atv's on the channels.

Maybe I'm getting Somewhere Now

Under the front cover it has AIL / ELV dual rates. TH.ATV for the HI and Low. TH Hold and Idle up pots, REVO. Mix UP and DOWN pots, PIT.Curve HI and LOW pots. The other switches are for servo reversing on all 6 channels, the other side has on /off switches to activate throttle hold and idle up, revo mix, rotor, and pit channel for channel 5.

So...now looking at it further do I want to activate channel 5 and use that as my hi and low pots to adjust as you said?

PAHelipilot,

Sorry to say, it doesn't sound like you have end point adjustments on all channels. Sounds like you only have end point adjustments on throttle and pitch channel. Wish I had a book on that radio and maybe then I'd be able to help you more.

Bad News

Sometimes bad news comes along. I have found out that I can use the gyro in normal mode by disconnecting the channel 5 at the receiver. Sure would be nice to be able to use the heading hold feature. I guess I'm in the market for a new transmitter at least.

I called Futaba to try and get some information on a set up with the 6VH, they were no help. I don't think he knew the difference between a helicopter and aircraft radio, pretty disapointed with the service.

Anyway, thanks again for trying to help me out.

Normal Mode

I disconnected the gyro from channel 5 this morning and added some revo mix. The helicopter wants to fly, I had things adjusted almost to a nice hover then the wind kicked up and I decided to run what was left in the tank and put the bird away before disaster struck.

Anyone here flying a Hawk with a 6vh system, what do you have your revo mix set at as well as the pot on the gyro, just for comaprison?

Things are looking up. In the meantime I'm going to keep my eye out for a different radio system that I can utilize the heading lock feature with.
