Had an interesting experience this morning. There I was, happily flying my heli, practicing side-ins, when all of a sudden it started doing pirouettes! I gently set it down, checked the tail, and spun it up again. Nothing from the tail... Did I blow the tail MOSFET? Did I cut a tail wire? Did the tail motor head off to the great motor graveyard in the sky?

Voltage was getting to the tail motor, but she just didn't want to spin. I guess it's time to swap it out.


I you fly a lot, you should consider the $65 BL mode from TheSteve including Losi motor, converter and ESC. I own several modified version of the DF4/Falcon and I don't have any of the tell issues you guys are experiencing. That tail motor is going to keep on burning out, I burned out about 10 of them before I went BL.

hi

i have a venom night ranger 2 which i believe is the falcon 40 rebadged.i crashed the other day and when i fixed it and began to fly i noticed that the tail rotar was pulsing all the way through the throttle range. any ideas whats wrong any help would be great.



Hold the heli on your hand and don't let the 4in1 get the vibration from the head (be very careful so the blades don't hit you). Increase throttle, if the tail stops pulsing, you know you have to get rid of the head vibration. If not than replace the tail motor thou I don't think there is ever a case a bad tail motor will pulse. Most of the pulsing problem comes from head vibration that transfers to the 4in1 gyro or the 4in1 is not tighten down enough to the main frame. Pulsing problems 9 times out of 10 are gyro related.

The best solution would be to convert the 4in1 to brushless and use a Losi 10,250Kv BL motor for the tail with a much faster ESC. A BL converter is available for $15 from TheSteve. I have done a diagram on how it can be installed if anyone is interested. The BL solution is well worth the effort for those who fly a lot.


I have a brushless main motor and have been looking at several brushless tail motor solutions. Feigao makes a motor that is popular and mounts directly in place of the OEM motor (will work similar to the GWS direct-drive setup I have). Medusa Research also makes a 12mm brushless inrunner.

Do you have a part number, or a link to where you got the Losi 10250kv motor? I'd like to see photos of how your heli is set up with the brushless tail



This is an AR6100 conversion with BL main and tail (2 ESC). It is extremely powerful and can manuaver in 10 MPH wind. This is like flying first class, cost about $200. To fly business class with BL tail and use existing 4in1, there is a $60 solution including BL Losi motor, ESC and TheSteve converter. It will completely eliminate the stock tail motor problem.


Your heli looks really great! I bet it flys like a champ too. I don't think that will be the solution for me however. I purchased this heli as a low cost trainer. I want to use it as a stepping stone toward the eventual purchase of a 450 or 500 class CP bird. Coming directly from flying the CX2 as my first heli I wanted a low cost to buy and repair single rotor. If I had made the jump directly to a 450 CP I shutter to think how much $$$ I would have shelled out in repairs. I guess my point is that if I was going to drop $200 on any heli right now I could buy a Belt CP. I just want to put the money into the Falcon neccessary to have it flying well so that I can practice orentation hovering and FF in prep for the next step. That is why I thought I might strip the CX of it's ar6100 and buy a 3-1 for the CPP to put in it. I would be glitch free for less than $40. I would of course eventually have to put the Rx back into the CX as it's too much fun not to fly. That is a problem. The specktrem Rx I would need is $50 and then we are talking about $90 for the mod which is more than I would want to commit to a mod for this heli. For that money I'll just fight the tail on mine. Who knows with all the tail battling I would be a ringer on a bird who's tail is solid

Now that I feel like I have "mastered" tail-in hovers(by that I mean I am no longer crashing in that orentation) I am working on side-in. I did have a few crashes this weekend working on it including one into myself which blew the fuse installed on the main motor. Man am I glad I did that mod. I'd be looking at a smoked 4-1 for sure. It really smarts too!! Again a CP amchine would have been far worse in that circumstance to me and the bird. As it is I just have a smallish bruise on my knee. No other damage during my attempts. I am improving on it though. I have been able to get it side-in for 1min + at this point. Having only started to train in that orentation on Friday I feel pretty good about the progress to this point. I will continue to work side-in until I can hover an entire pack that way and then will move the tail on to nose-in and then the real crashing begins [)]

Have a fantastic Monday all you dirty hover heads


Last year I was doing exactly what you are doing. In the end I did both. I built 2 Trex 450 v2 and modified 2 DF4/Falcon 40 and 4 DF4#3. Because I live in southern California where there are few vacant fields, my Trexs ended up collecting dust. The DF4#3 and the DF4/Falcon 40 mod which I spend quit a few bucks but were worth every penny. Last month my heli repair bill for the mods were close to nothing. They are flying too perfectly and when I do crash nothing would break. I fly them every day infront of my drive way and the 4#3 in my bedroom at night. There is no need to drive 45 minutes to a field anymore. I only have to crash 2-3 times on the Trex and I would be able to pay for one mod. Trex SE450 is probably the cheapest 450 to maintain but it is still expense to crash, so I invested on DF4/Falcon 40 and make them virtually indistructable.

I have been flying a Falcon 40 for a few months and I think the main motor is about to gone bad. Last night, on a newly charged battery pack, the main rotor would only turn a a low rpm while the tail rotor would spin the heli all the way around while it was sitting on the carpet. As I said, I have been flying/crashing for about two month and these are the original motors. The original/stock battery pack read 9.3v on a digital multimeter. Also, fow a while now, often on the first flight of the day, at first the heli would not even get off the ground, but then after things 'warmed up', it would have enough power to lift off. Is this a sympton of a bad motor or battery pack?

Anyway, my real question is: When buying a new main motor, what pinion do I need? I think a 10t, but want to make sure. Also, I know about the Mabuchi motor from Tower Hobies, but they are out of stock right now. Does someplace else sell them? I would get both a main and tail motor. If not, my LHS sells two different motors that I think will work, one is an E-Flite, are then any good?

I am running a totally stock heli (except for servos (HS-55's)) with the 7 cell nimh pack. I may look into doing the GWS tail rotor mod though.

I think the Faclcon 40 is great for the price and Michael at USHobbySupply has great service, he just does not have a motor upgrade that I can tell.

I just did a motor up grade from Michael, I used the HM-22E-Z-17 - Walkera 22e Main Motor as per his web site, and after an email to him. The 22-E motor has more than ample power, and an internal cooling fan. It works perfectly. The leads and diode need to be reversed which is no problem if you can solder, is not Michael wil do the lead swap for you. for $10 is is a good deal. Also I added an external heat sink ti the motor at the same time.
Have A Great Day

Thanks, but I still have a few more stock main/tail motors to run through. This tail lasted me 4 months, so we'll see how the next one does. After I run through my stock collection, I'll have to decide on what to do next.

Besides, I like the glitches! (actually, I don't have any glitches at all). If I can fly a twitchy heli in a controlled manner inside, then I'll be OK for flying a bigger one outside (with wind gusts).

Status: offline 		Well it was as I suspected. The main was going out as well as the tail but it was tough to tell as lift was still doing it for me. I went today and picked up the main for the CPP. I already tried the CPP tail motor with 0 success and ended up putting the OEM motor back in. The motor I picked up has and 11t pinion on it as they were out of the 9t variety. I have a pinion puller so I just thought I'd pull the stock pinion and put it on there. Well I thought what the hay I'll go ahead and give the 11t a try with the CPP tail motor. I thought for sure that I'd be spinning my wheels. Much to my surprise when I fired it up for a test flight I didn't even have to adjust the pot and the tail is more steady than it has ever been with more authority Seems like the 11t would so drastically overpower the rotors the tail would not be able to keep up. My headspeed is up so my hover is more stable. All in all I had a very pleasent heli day For only 10 bucks that motor is a great option for my replacment purposes and stocked at the LHS to boot. I did notice that my flight time is down a bit. about 1.5 min so not too much but i wonder why. Maybe when the motor becomes a bit more seasoned it'll give longer times. Still have 9:30 sec of flight though on my 2s 900 lipos. I might try the stock pack in this configuration and see how it goes. It's good to have all the tail problems I have been having behind me so i can get back to training.

I have had another intresting experience last night. Got into a small scrape with a cardboard box on the floor of my garage. I had cut the throttle but the blades were still spinning when I hit it. No damage that I can see but all of a sudden my blades are not tracking in line where they were before. I have taken the head apart just shy of pulling the pin and have no cracks in the rotor core. No broken blades. No damage whatsoever that I can see. The shaft is straight..... Any thoughts?

Hope this answered your question stalled.

Dave sorry to hear that now you are having tail issues. Hopefully a replacment motor will do the trick. keep us updated.

Happy hovering all!!

Sorry to hear that incident in the garage. What is it doing now when you try to lift off? I am suspecting that you have a hair line crack at the head connector. You guys should go
