Hi guys I am new to the forum and hopefully some of you guys can help me out here. I have a blade cpp which is stock except I just bought a g110 gyro for it. Now heres my questions. I am running it with the 5th channel setup so I can adjust the gain from the TX. Heres the first question. When using the remote to adjust the gain what should the gain be set on the g110 itself? Do I turn that down all the way and just use the TX to adjust it or do I turn it up all the way on the actuall g110 and still use the tx to adjust it. The instructions say that you have to turn the pot all the way down on the 3 in 1 but I have read that that is wrong and you have to actually turn the gain all the way down. Is that right? Leave the pot alone and turn the gain down? I've tried it both ways and the problem I am having is the heli just wants to spin counter clockwise in super fast circles. I know I have all my wires setup right because the heli flies fine with out the g110 on it. I am still running the stock rear motor but have a dd setup waiting to be put on. I want to figure this problem out before I start adding more parts. My LHS is pretty much useless on helping me they didn't even know you could hook up the fifth chanel for TX adjustability. The guy said "I always wondered what that extra wire was for" If someone could give me a good starting point for this or a link I would be really greatful. I have a 60 dollar part sitting here and its getting no use out of it. Heres a review of my questions...

I am using my remote to adjust the gain on the g110 via the 5th channel. What should the actual gain be set to on the G110 itself not including the TX? Do i turn it all the way down or all the way up?

Do I turn the 3in 1 gyro gain all the way down or do I turn the pot all the way down like the manual says?

Do I mount the g110 straight up and down with the lable facing the back or do I put it on its back with the lable facing up?

Please help me out rc universe your my only hope!

To try and fix the spinning you can try reversing the gyro. Might help, might not.

Hey ebaysrt4,

I just got done doing this, except for I am using a DX6i TX, instead of the stock radio, but most everything should be similar. First of all, let's get the pot/3 in one/gain setting straight...as I think you might be confused...

There are two pots on the 3 in 1, one is for the gyro gain, and it is labeled "gain". Then the other one, to it's right, is the proportional pot, which controls the relationship between the main motor and the tail motor mixing.

When I just did mine, and I used the TX to control the gyro, I first turned both gyros OFF, both pots (the one on the G110, and the one on the 3 in 1) to zero, and the TX gyro to zero, and then spooled the heli up, hovered it, and adjusted the proportional (right pot) on the 3 in 1 until the tail was staying centered.

Once I had that figured out, then I applied a good bit (70%) of gyro through the radio, leaving both pots on the G110 and the 3 in 1 alone. I had very good results doing it this way, I would try it and see how it works for you. This should put the G110 in Heading Hold mode. I can't say for sure, since you are using a totally different radio, but the principals should be the same.

The gyro should be mounted so that the label writing is upright, and I faced mine towards the rear of the heli, on the little mounting pad behind the rear servos. In other words, mine is facing the rear of the heli, with the label readable from the rear (hope that makse sense) I would post a pic, but I am at work.

Hope this helps, let us know how you make out....

ebay,

Also, I almost forgot, when adjusting the proportional pot, you have to unplug the motor, and then make your adjustments, you can't just turn it while the 3 in 1 is powered up. But, the gyro gain can be adjusted while the 3 in 1 is powered up, if need be.

Glenn

Once you've connected the gain sensing lead from your g110 to the 5th channel of your receiver, you're now automatically in HH mode. Thus, the gain pot on your G110 is now disabled and it doesn't matter where you set it. From this point on, all gyro gain settings are done via your radio. The pot on the gyro itself is ignored.

ndoren,

Good point, I think I read that somewhere as well.

I also believe that I read (or at least it gave me the impression) that the HH mode is dependant on where the TX setting for the gyro is...less than 50%, and the gyro is in "rate mode", and greater than 50% puts the gyro in Heading Hold mode...just going from memory here, hope that is correct...

Glenn

In the G110 manual it says you can be in standard or HH mode when the gain wire is plugged into the 5th channel. It is under gyro connections to receiver then Dual mode connections. And it is in the second paragraph of that. http://www.e-fliterc.com/Products/Su...dID=EFLRG110HL

Hey guys,

I just got done re-reading my CPP manual on the gyro installation. It wants you to adjust the proprotional pot all the way down, all the way counter-clockwise.

I don't know, seems like last time when I tried that, it didn't work so well. It's up to you, but my CPP is flying great with a DD tail and the G110, setup as described above...

In any case, good luck with it. It is very liable to take some experimentation to get the best setting for you.

Glenn

Glenn,

I wonder why they stated that in the manual. How does the tail motor get its power? Or if some how the signal coming from the gyro allows it to get more power from the 3in1.

It sounds like your set up is more logical and it is working for you, so that is all that matters.

The UPS people are delivering packages right now, so I hope I get my motor before I have to go to work.

Nick

Nick,

If I remember correctly, I struggled for a while trying to setup the G110 the first time according to the manual. Then someone straightened me out with something along the lines of what I used to set mine up yesterday...that is, get the proportional right, THEN worry about the gyro secondly.

It worked for me, so that's all I can say.

I hope your UPS man brings you lots of goodies!

Glenn

Glenn,

I really want to get as much done on the CPP before I go to work, but last time I got something from UPS it was around 7 and I will be at work by then.

I am wondering if I could use my GY240 with the brushed ESC. It seems that everyone who has tried a different gyro than E-Flite with the 3in1 the tail motor will pulse and not maintain the RPMs needed. I will have a lot to experiment with.

Nick

Nick,

Yeah, I have gotten stuff from UPS really late in the day as well. Hopefully, you can at least check the stuff out tonight after work.

I just ordered extra black tail rotor blades for the CPP, since it looks like they might break pretty easily.

You will have your work cut out for you with all the CPP experimentation you are planning, but that is half the fun...

Glenn

Glenn,

Yeah I will have a lot of fun working on the CPP. I enjoy working on helicopters as much as flying them. But I also want it to be done quickly, so I can go test fly it.

Nick

Thanks I will try that. I wasnt sure if when running the tx to adjust the g110 gain if it disabled the manual gain on the g110 thanks. Im out of town till Friday morning so I will try this when I get home. I ordered some superskids and new blades and they should be there when i get home. Thanks guys I will let you know how it goes.

Hey just wanted to give everyone a update on this. I did everything like glenn stated and it worked. The problem was that the instructions say to put the g110 on reverse and my heli did not like that at all. I switched it over to standard and it fixed my issue with the heli spinning out of control. Here is what I ended up doing.

Set the gains on both the 3 in 1 and the g110 to all the way counter clockwise as well as leaving the 5th channel on the TX all the way down.
Switched the g110 from reverse to standard.
Adjusted the pot till the heli would get a good hover right from take off.
Turned the 5th channel on the TX up to about 85 percent with no issues with spinning.

After doing this the tail seems rock solid. I was using RRADS school of flight to learn how to fly this thing and had no problems keeping the heli hovering very stable in a 10x10 square. It would even hover one handed which I could never do before. Finally I do not regret purchasing the G110 Head locking Gyro. Thanks Glenn for all your help. Your advice helped me out TONS. I also just installed my superskids on it and other than being a major pain in the ass to figure out how to put it together I am very happy with. The heli feels like the chassie is alot stiffer now and no broken landing gear.

Hi ebaysrt4,

Wow, I am glad I could help so much! And very glad to hear that it worked out well for you...it took me a while to figure that out myself.

I don't know why, but somebody messed up when they put that setup info in the CPP manual, I never could get mine to work correctly that way.

But I just put 2 and 2 together, and started thinking about what each adjustment does, and it started to make more sense.

Glad you figured out the reverse setting as well, that can drive you crazy trying to figure that out as well.

Now all you need is the GWS direct drive tail setup, and you will be rockin' !!

Glad I could help. There was a time, not too long ago, that I was the one ASKING all the questions!! Now it feels great that I can return the favor now and then.

Enjoy the CPP!!

Glenn

I actually have the direct drive setup sitting right here. The problem was that it came with a new motor mount and when I was having problems with the g110 it spun like nuts it landed and snapped it in half. The motor I have will not fit in the stock holder because this motor is all the way round with no flat spots on it. I think I can just make some cuts to make it fit but I am just going to wait till I get the right part for it.

I am using the stock motor mount. I just used a X-acto knife and if fits just fine. You have to make the rotor spin down away from the main blades or the helicopter will rotate left with right rudder.

Nick

Does it make that much of a difference?

What difference are you talking about? (With the stock mount to the GWS mount, the way the rotor spins, compared to the stock motor)

Nick

no no sorry should if been more specific. Does having the DD make that much more of a difference opposed to the setup with the gear.

Not to confuse the issue, but I'm stumped as to why anyone dials in any 3-in-1 proportional at all. At least for heading hold (HH) mode, the external G110 gyro handles all aspects of tail control. Thus, there should be no proportional needed and no revo mix needed. I don't use any proportional or revo in HH mode, and my tail holds rock steady.

Im not sure. i just set it up the way Glenn explained. It seems to work. And if you dont have the pot setup what happens when your not in HH mode? Does it still work out ok?

ndoren,

I use that method because it has worked for me in the past, so I stuck to it. I have never tried using no proportional...it may work just fine without it.

Just a creature of habit, I suppose. If I find something that works, I usually stick with it.

But I am open to any new suggestions as well. I have never tried it with zero proportional, it is probably fine.

All I know is that my CPP is flying better than it ever has!! By a long shot!

I may be mixed up, because I used to fly mine without the TX controlling the gyro...basically in rate mode, and was adjusting both gyros with the pots on each one...and getting really mixed results. I finally set it up in HH mode, and that made all the difference for me.

To each his own...I am just glad everyone has their CPP's flying well lately!
