Gain/sensitivity is for the gyro. Too low and the tail will drift, too high and it will wag back and forth. Extent is the amount of servo travel – how far the servo arm moves at full stick. If you have it set too high you’ll over control the heli… BUT as your flying skill improves you can increase it and make the heli a little more responsive. Neither one is part of this problem so don’t mess with’em right now.

The receiver antenna is ok bent (just don’t bend it back and forth or it’ll break). I just wanted to see if there was anything near it that might cause interference or block the signal. It’s the transmitter antenna that should point straight up – but even it shouldn’t cause the range to be as short as yours is.

I have known plank fliers who repaired a fuselage with carbon fiber that blocked the signal. JB weld has metal filings in it and will block the signal. If you’ve repaired the canopy you may have found a new way to block the signal so test once with no canopy.

With these radios (walkera) the binding sequence is transmitter first then receiver. A walkera radio will ONLY bind with another walkera, and even if you have another guy flying a walkera 3 ft away they still shouldn’t be a problem (my brother and I do it all the time).

There are only a few things that could be the cause-

A very strong signal that is interfering. In the old days we had problems with transmitters for pagers being nearby. With these radios interference is very unlikely but possible. You might test it in a different location if you haven’t yet, but I wouldn’t expect to see a change.

An object(s) blocking the signal. You aren’t flying behind a building, tree, etc. so that’s probably not it. Repairing the canopy with carbon fiber, JB weld, or a conductive paint, etc. would fit in here.

Antenna problem – broken wire or bad/cold solder joint. Any time I hear reduced range I think antenna first. You said you only just started flying it at any range and it never has worked quite right? It could very well have left the factory with a problem. If you are confident with a solder iron you might melt the solder on the antenna joints and see if it helps. If you aren't confident, then don't.

Bad transmitter or receiver – anything other than the antenna. The problem is troubleshooting is almost unheard of. Way cheaper to just replace.

At this point you don’t know if it’s a problem with the transmitter or receiver.

My suggestion would be go to the walkera forum (it’s an electronic heli sub forum in that list at the top of the page) and see if you can find someone nearby with a walkera 4 channel radio system. This could be a Walkera 4, ufly, 4g3, 5-6… any walkera that is 4 channel. You can test your heli with a different transmitter and your transmitter on a different heli. Don’t try to fly someone elses heli, have them hold it while you walk away, then you hold yours while they walk away

Thanks Karlik,
Great advice and info on the Extent/Sensitivity. I will start with a look at the antenna connection. I have a hand lens and will take a good look at it. I have pleanty of crashes that could have affected it. I use scotch tape on the canopy so that shouldn't be an issue. No carbon fiber in the canopy, although the original green canopy had a windshield that looked like carbon fiber. I don't have access to another transmitter, so the next step may be to buy a whole new Falcon V2. I hope one of the other issues is the answer.

Thanks again,
Pat

New to the forum.
I have had a Falcon 40 for about 3 months. I am becoming a good mechanic on it and have stocked up on spares. I can hover tail in for an entire Li-Po battery, but crashes are worse as I practice higher.
A couple weeks ago the motor, even at full power would not lift the helicopter. Swapped motors and same thing. Swapped batteries same thing. Measured voltage out of battery...8.4V. Measured going to motor...8.4 at full throttle. Turning main gear, it looks like it might be stripped on the main shaft going to the rotor head. Is this common? Do I need a new rotor head or main gear with shaft?

Thanks,
Mike
BTW, the main motor I ordered from Exceed had the sticker over the vent hole.

If the rotor head is spinning while you hold the main gear. The small pin on the rotor head may be missing. This pin goes through the rotor head and shaft.
Also, its been my experience that the main blades could be damaged. They may look fine and track fine but the pitch is off and so they might need to be replaced.
Chech the main gear for wear and that the motor isn't loose. You can order a main gear from https://www.ushobbysupply.com/product_info.php?products_id=31
Some people use a paper to set the gap between the gears.

Thanks for the input. As I looked at it closer, the pin was there but spinning the blades was not moving the main gear. The shaft was moving at the blades so I looked on the bottom and the set screw at the bottom, holding the shaft to the main gear, was loose.

Thanks again, I am sure I will be asking more questions!

I'm trying to track down a problem. Let me see if I can describe it in a way that makes sense. When I'm hovering level and still (main rotor blades parallel with the ground), my heli is stable. However when the heli starts to drift and I correct with cyclic (now the main blades are no longer parallel), the helicopter "wobbles". I can feel this same behavior if I hold the helicopter and throttle up. If I hold it with the main blades level with the ground, it's smooth. But if I tip the helicopter in any direction, I can feel the "wobble".

I've looked for loose stuff, checked for cracks, etc. Main blades are balanced. I've triple checked that the flybar is centered (both with measuring tape and just checking balance with main blades removed).

It didn't used to do this so something isn't right. I'm surely missing something. Has anyone else experienced this? Any ideas on where I should look more carefully?

Thanks,

Drew

I had this problem with my Falcon V1 and I think it was due to too much weight. I replaced the cnc upgrades and superskids with the parts from the V2 and that greatly reduced the wobble. If you haven't added weight since it worked right before, that may not be the problem. I am sure there are other sources for the wobble like the loose lock screw on the main shaft/main gear, or the paddles aren't lined up right with each other.

I had this problem with a V1. It like to drove me nuts. If you have a new one try replacing the blade grip. I know that it may feel good and you cant see any cracks or anything else, but just try it. On mine, there was just a little slack on one side where it snapped over the bearing. This was almost undetectable, but it was there.

Thanks guys. The only extra weight is training gear so I don't think that's it.

I have another blade grip on order so I will try that when it arrives. Well actually I have a spare aluminum one for my Walkera UFLY (nice and stable BTW) but I'm going to save that. In fact, the reason I have spare plastic head parts on order is that I've learned that the metal ones on the UFLY bend very easily in crashes and are quite expensive. I ordered the plastic parts to put on the UFLY while I'm trying to learn controlled slow forward flight.

I'll report back once I have a chance to try it.

Also open to any other ideas in the meantime.

Thanks,

Drew

I was looking at the parts list for the v2. What's the difference between the "rotor head" and the "rotor head core"? Does a rotor head include the core? Would someone please enlighten me?

Thanks,

Drew

P.S. Still waiting on the blade holders. I did find the lock screw on the bottom of the main gear loose. I've tightened but still have the wobble.

If it is shaped like a Y then it is the V1 rotor head and called a rotor head core. If what you need is the V2 rotor head, it looks like it has a metal pin through it. That is for the V2 and has a separate set of blade holders. If you use this xheli site http://www.xheli.com/falcon40parts.html the rotor head (50H01-01-1) for the V2 is the first item. It does also fits on the V1, and I like it a lot better than the old Y shaped core(50H01-14).

OK, thanks. I wonder why xheli has a v1 part on the v2 page? I couldn't figure out the difference or even where that "rotor head core" would go on my v2.

Thanks,

Drew

I wonder if your wobble is induced by the training gear. Is the training gear loose?

Anyone here have one of the new Walkera Flybarless helis? I'm debating my falcon 40 (need of bigtime repairs), flybarless fixed pitch or my CP 450 with a buddy box to help train my son outside.

HI all,
A comment and a question. I ordered a new receiver for the V2, RX2421 from HeliPal.com two days ago. I just got the following response:

Dear Sir/Madam,

Sorry that it's been Chinese New Year, all factories in China closed from 15 Days to 25 Days, our stock are running very low that we can't restock in a short while. We're sorry that the item below are just sold out when we proceed your order:

1 x HM-4#-Z-30 Receiver (RX2421)

Would you like to:

1. Wait for them to send the complete order,

2. Replace them to other parts.

So don't trust them if you are in a hurry or don't happen to know when Chinese New Year is.

QUESTION:
So... my receiver is out of whack. I was happily hovering the V2 and just brought it down with just a little bump. After it landed, I had no throttle or directional control. I thought that perhaps the battery was dead, so I switched in a new battery and re-synced the transmitter. I noticed that I didn't get the buzz-buzz sound when I connected the battery, but the flashing red light came on. After I got the double beep from the TX still no control of throttle or directional. I took the canopy off and the RX seemed a little warm and had a slight electrical smell. I have double fuses on the motors, and like I said there was no motor lockup and all the fuses were fine. I have a #3 fuse on the tail motor and a #10 on the main motor. I removed the plastic wrapper from the Rx and couldn't see any burn evidence, and no strong electrical smell.

Any ideas what happened, or where I need to strike the RX with a ball peen hammer to fix it.

Also it seems that the RX is sold out everywhere. It was about $44+ at HeliPal vs 57+ at Xheli. It is out of stock everywhere I looked.

Pat

AH HAAAA,
I figured out what was toasting my RX. It was one of the servos. I got a new servo from rtf-heli and was just doing a connection test before hardwiring the fuses. the motors were working fine, then I connected the servos and I started to smell that bad electric smell. I quickly disconnected the power. I then got the old RX which I hadn't used a hammer on yet and connected the servos one by one. One of the servos immediately heated up the RX. I got a replacement servo and all is well. I may even be able to use the old TX, but it will be a while before I test it. Has anyone heard of this before, and do you suppose there is a need for fuses on the servo too?

Pat

I have never seen a short in a servo.
What brand are they?
Why don't you pull it open and ohm the wire ad see where the short is?
May be fixable, unless it is on the PCB.

The bad servo was an original that came with the V2. I have some generics that I have to make fit, but they work just fine. I am still testing,

I changed all my servos to HItec HS55's really like them.
http://www.helidirect.com/hitec-hs55-hitec-feather-standard-servo-p-427.hdx
Like all non OEM servos they need a little help to fit in but a single Zip-Tie on eawch one as a safety is all you need.
