Hey Rollin:
I discovered a problem with the DD Tail Rotor we've been using and wondered if it has affected you.
I noticed tail wagging begin a few days ago and upon close examination of the motor, adapter and rotor blade, I could clearly see that the adapter (which is really tiny) was bent. Has this happened to you? Does there exist a more substantial adapter we could use for this system? Thanks.

Yes I did thats the reason for changing the tail motor.I thought it was the stock motor making it do it. But it did not change after installing the ductfan,

Well, if it was mine, the next thing I'd do is replace the main motor with a stock one or an E-flite/Esky 10T motor. At this point the 4in1 is usually the first thing blamed, but the last thing to actually cause a problem. I'd try a new main motor. If I just replaced the main motor, I'd still try a new one.

In order to solve the problem, we have to take it in logical steps. The first would be to fix the gyros. The 4in1 must be standing up as it does in a stock DF4. The added gyro must also be upright. I'm not really sure how you tied the outboard gyro into your 4in1 and it would be easier to solve the problem without it, but I'll assume you found a way to wire onto the 4in1 board between the 2 ESC circuits.

If the problem was happening before you added the new tail, gyro and turned the 4in1 on its side, then it could be a glitch cause by a bad connection in the motor's JST connector. Whenever I've had a glitch, it's been caused by a bad electrical connection. Sometimes rerouting the antenna can help (but not stop it altogether), but fixing the right connection will stop it.

I use the same gy006 gyro in the #4 and works great with the stock tail motor, you have to position the gyro upright (when you can read the blue label), not side way. If you use the stock #4 radio, set the AVCS on and gain/sensitivity at ~55%, you're good to go. If you use other Tx, make sure the Revo mixing is off in the AVCS mode.

After many crashes with the DD I have not had that happen. What you are looking at is crash damage. It's not a problem with the adaptor it's just damaged. Really we don't have any room to complain compared to most others here. So far it has been as reliable as my belt drive heli. Answer me this. Before now, when was the last time you even thought about your tail? I don't know of any adaptor that is stronger steel. I would just replace it. Hell it's even cheaper than a stock motor

If youy are using the stock RX where are you plugging the gy006 in?

No, I went separates when the 4in1 quits after 55 flights. Do a search, I did a BL setup here also.

With the gy006, all you need is a regular 4 channel radio, that's beauty of the HH gyro, you don't have fool around with the Revo or throttle/rudder mixing.

Gidday all,

I am still considering what my options are for the tail motor setup with the DF4#1. I am reading godd things about the GWS direct drive setup. However, with all the information in this thread, I am having trouble knowing exactly what parts I will need.

Has anyone got a list of GWS part numbers?

I belive I need:

Direct drive motor
Mounting fin
Blade adapter

Any assistance would be appreciated.

Thanks,

Steve

Well, learning to fly the dragonfly progresses, I can keep it in the air for most of a battery, but not really hovering as it takes me about a 15 foot square, which I can barely keep the heli in...

My original reason for getting my walkera came from an interest in micro-controller development and robotics, I had wished to make a small heli "fly itself" the DF4 seemed perfect as it is a fixed pitch heli (less for the computer to do)...

To this end, I am developing a small board (same size as a small receiver) with some sensors (of different types) that will plug in between the receiver (until the receiver is not needed at all) and the servos, motor Esc(s), etc... with my board actually controlling everything, and the receiver just giving it directional inputs, to do this I must go separates, my board will be able to receive and send servo type signals,

I think I need to get: (tell me what parts you recommend, and tell me if I forgot something I need)
Gyro (heading lock preferred)
main Esc
tail Esc
servos (better then stock)
mixer?
bec?
receiver (4-6ch)
tx

P.S.
I am not expecting any of this to allow me to fly the thing better, just so I can connect a computer to fly it for me...

richcreations,

I think that would be very cool to see indeed.

But first, before you could do that you would have to really understand how to control your helicopter. The DF4 is a great helicopter to learn on because it is so difficult to fly that when you move to stable helicopter you are like an expert!

Second a couple of people I have seen go seperates with the DF4 are locked into problem after problem mode. Either with the gyro or getting an esc to arm right. Seriously I would suggest looking at a different platform, such as one that is already 98% what you need. If you want to push forward with this all-in-one dual engine platform, I might suggest you look at this persons helicopter and shoot him a PM. By the way that's a Heli-Fever.com frame.

Very interesting project! Please keep us posted.

I agree Rollin. It's a great set-up and yes, I did slam the tail which probably resulted in the bend. With this in mind. I'll just reorder a few extras plus the replacement. By the way, the motors sure seem to last quite a while!

I read an article awhile back, someone writing a program to port to Linus system and successfully controlling RC helicopter using the infra-red interface. Google it.

Can anyone help me my tail motor keeps surging for some reason. If I unhook the main motor and run it the tail motor runs great, but when the main motor running with the tail motor will run hi lo, sometimes spinning the heil into 360 turns. I just install the ductfan tail and upgraded the main motor. Even took a old WK-G006 gyro i had off my #36 I dont us anymore works great with the new servos. With the new superskids it looks great . Now the problem the tail motor, need help
Looking at how you have the gyro mounted that looks to be the cause. That gyro needs to be mounted upright, NOT on its side. It will never work proparly with the way you mounted it.

This is what i bought I'm happy with it so far, everything came in one peace and works great. Once I balanced the blades and took off the training gear it actually hovers like a dream. This is my first RC anything and i can hover tail in and nose in after the first day. Not to bad. My only problem is the battery didn't come with instructions and i don't know how long it takes to charge it. I assume the red light turns green when it is charged but I'm too afraid of over charging it. If anyone could help me out the link is at the bottom for the kit i bought.
