Status: offline 		well i checked whole charger , not a single LED on it....double verified it with a friend who got it at the same day , no led indicator at all.......... now im thinking if i should send it back to HL or just save the shipping money and buy me a aftermarket charger. if the owners of the new batch ones get theirs pls verify it here and let me know if your charger writes Ktec on the front with no led on it

hey gary , for a trex450 , how many cell batteries does it need? so i can figure out what type of charger to get in hobby town.

Status: offline 		Yahoo! My falcon arrived today!! The bad part is I'm stuck at work I did get my son to pull the battery and charger out so that I'll have a charged battery when I get home. As evoIX pointed out in his post, my son can't find an led indicator on the charger either.

I'm going to have to check this out when I get home. Anyone know what voltage the battery should be at when it is fully charged. I can't believe that they would put in a charger with no indications on battery status. Will these chargers detect if the battery is fully charged and shut off automatically? The charger has Art-tech inscribed on it.

Anyone else get their Falcon today and running into the same problem?

Status: offline 		evoIX you will need a three cell charger, generally Lipoly chargers will charge between 1-5 cells, some do auto detect. The charged state of a 3-Cell Lipoly when the charger shuts off is 12.60 volts. After it sits for awhile the voltage will drop off to somewhere around 12 volts. It is imperative that it not be charged over the 12.60 volts for a 3 cell pack.

Status: offline 		Hey guys, these chargers are designed to be used from a car battery, otherwise how else would you charge them at the flying field? Your charger should never exceed 1C or simply stated 1 times the capacity of the battery your charging. The Falcon battery is rated at 1300ma or 1.3 amps. You would set your charger for three cells and charge at 1.3 amps. All Lipoly chargers use what's called constant voltage constant current charging method. As they start out they test the battery an do a low charge which gradually increased to the capacity you set it at. It's always a good idea to keep and eye on your charger since errors can happen and if you setup the wrong number of cells you could risk and explosion or fire.
When you take off your blades and run the motor up you run the risk of over reving your motor. It's designed to work with the load of the blades so don't try to run long periods of time or at high throttle settings with the blades off! Put your training gear on and just try little hops at first. Limit your flights to no more than 5 minutes or you risk overheating the motor. The motor is designed to run at 80% throttle setting for best results. When you use normal mode you will never reach 80% power and your speed controller and motor will get hot! Once you learn to fly and can switch to idle up or 3D mode, you can fly all out without overheating your motor, battery or speed controller since it's running in it's designed parameters. You see, many of the problems new pilots have are a direct result of not knowing these things, they then wonder why they burn up their ESC's, motors and batteries. Do not fully discharge your battery either or you will permanently damage it. The ending voltage of the battery should never be below 9 volts on your Falcon battery pack.
I hope I've cleared up the fog for you new guys, follow these simple rules and you'll be rewarded with a long lasting great flying bird!

As a side note Thunder Power says you can charge their batteries at 2C but I wouldn't recommend it since fast charging will shorten the life of the battery. Also anytime you change the charge rate to a higher rate than recommended your going into uncharted waters and could be greeted by the sweet smell of Lipoly smoke and fire!

evoIX, no way!!! I'd have to charge a zillion lipos without ever running the car (& thus charging the battery off the alternator) before the car battery would even notice!! so no, charging off the car batt no big deal & very common

I personally prefer a DC (car battery)-to-DC (lipo) charge, as opposed to an AC (wall charger) charge, since the charger must convert 120V AC into 12V DC (for the lipo)

it'ss chg 3 types of batteries: NiCad, NiMh, & Lipo

the other great thing about the hobbico is that I can charge 2 batteries at a time in the field where I fly, without having to drive home & plug in a charger (therfore, wherever the car is, the charger is!)

the hobbico will only charge to a max 12.2V DC on an 11.1V DC lipo... the user cannot change this.. but the user CAN change the milliamp charge rate from a trickle (e.g. 200mAh, generally better for lipos) to up to 1.0Mah

plus it has both audible & visual alerts, and you can hook a voltmeter up to it (good to see whether the lipo is good; i.e., can hold a full charge)

lastly, off the hobbico I can use both banana-to-standard JST (for low dischg 10C etc) & banana-to-Deans Ultra (to chg hi-discharge packs such as 20C etc-)

to sum: very versatile, convenient, and backed by a 2-yr warranty

hope this helps & good luck!

evoix, I think due to lipo volatility and for safety reasons, most lipo chargers (at least that I've seen) will only charge at a rate of a max of 1.0mAh, regardless of what you set them at (assuming there are user-configurable controls).. I'm not familiar w/ the Dynamite charger; but again, for me, I like a DC-input charger (as opposed to an ac wall charger) wherein I can charge lipos where ever my car is... for example: for my Blade CP I have 3 lipos that I got from commonsenserc (which I HIGHLY recommend)... so in the field where I fly, it's convenient to be able to have 1 or 2 batts on the charger, on my car, a few feet away; while I'm flying on the other one.. this way I always have a fresh batt & max power!

the "C" you refer to is generally the discharge rate in amps (as opposed to capacity; others corect me if I'm wrong!).. meaning: a "high C" battery (say, like 15C, 20C, etc) has a high "spike" amperage that allows you to throw a WHOLE lotta juice to the motor for a short period of time

also, when charging lipos normally, they stay at ambient temp.. the only time mine have felt warm is after some aggressive flying; and even then, they're barely higher than room temp (as opposed, say, to the NiMh batts, which get REAL hot)

generally, unless your battery is "visibly puffed" (swollen) you should be ok

again, for me, I like to know what the voltage is of my fully-charged batts are; and the only way I know to do that is a voltmeter:

http://www.helidirect.com/product_info.php?cPath=62&products_id=849

I use this little Esky voltmeter and it works like a charm

Plus, I'm an unabashed supporter of helidirect

so in sum: I think your batts OK!!

***here's what I do know: with helicopters, you can get in really deep- they are (to me) incredibly complex and well-engineered machines.. and I've heard it said and now I believe it:
when you take up heli flying, it's not a date- it's a marriage

easy to get frustrated; but for those that stay with it, it's beyond amazing

good luck
jeff

Status: offline 		WARNING - NEW FALCON OWNERS

I was very surprised when my replacement Falcon was delivered today ! My first one was returned when the ESC failed and I've been waiting like the rest of you for 3 weeks.

So I take everything out of the box, first thing I do is plug in the charger and start charging the battery. Nope ... no LED here either. Maybe you charge it until the battery explodes ... I guess that would indicate a full charge, huh ? I did notice the second time I charged it today went I went to retrieve it (I charge outside now ... too many scary stories) the charger was cold. Could be there is an internal cut-off ?

Anyway, I remember Gary's advice and with screwdriver and allen wrench I go over the Falcon from stem to stern physically tightening everything. I did notice all the servo screws seemed a little loose to me.

A few hours later, with the blades balanced and every nut and bolt checked, I hit the garage for the first hover. Ease up the power, the Falcon spools up nice and steady, then pops up about a foot in the sweetest hover I've ever seen. Nice and stable and sounding like it's got power out the wazoo !

I sit her down and catch my breath, ease up the power and she pops right back up about a foot. Nice hover ... very little drift, I let her fly for 15-20 seconds and slowly bring her back down. Just before she touches dirt something breaks off the tail, wiz's over my left shoulder and hits the wall like a bullet !

I kill the throttle, shut everything down and give it a look-see. One of the rear blade grips is missing, the tail rotor assembly has rotated about 30 degress and the rear guard looks like something nibbled about 1/8 inch off the edge.

So I spend an hour looking for the tail blade amongs all the crap on the wall of my garage. I find it intact and showing no damage.

Long story short ... looks like the Art-Tech people didn't tighten up the tail blade grip screw. You have to remove the tail blades to get to this screw, so I missed it during the pre-flight check. Remove the tail blades and you have a hex-headed screw holding the tail blade grip to the gizmo that rides on the tail rotor shaft. I checked the other one and it was loose as well.

You might want to check those screws ... if that tail rotor blade had hit me it would have penetrated skin !

Everything's put back together, and except for the minor damage to that rear rotor guard I think I'm ready to try again. Course, I'm looking at another hour moving all that crap off the garage floor and back against the wall so I can fly again. Looks like flying will have to wait till tomorrow !

Good luck everyone ... let us know how your first flights went.

Barry

Status: offline 		Your probably ok even if you did charge it at 2 amps as long as it's not puffed or hot, either of which would mean time to put it in the trash. Lipoly batteries are fantastic for their power to weight but they do require some knowledge and forethought. As long as you had the cell count correct and it was charging in a lithium mode you'll be fine. As for me I rarely fly more than a few packs on each helicopter I have so I never charge at the flying field hence the use of a power supply I use instead of a car battery. Just use a little common sense and you should be just fine. Wouldn't ya know it Barry, Murphy's law strikes again, you tighten all the screws and the one you don't is the one that's loose. The tailgrip screws are one screw that should definitely have loctite on it since it has lots of forces working on it. If you have done any reading you'll find that Align had some serious issues with those same screws snapping off in flight caused by sideways thrust. Hopefully you'll not have anymore parts leaving without your knowing! That's the wonderful thing about the INTERNET and forums like this, we can share valuable information with each other so we don't make the same mistakes over and over!

Status: offline 		evoIX - I called HL about the charger but all I could get was the automated answering machine, so I left a message. After some research, I ordered a lipo charger ( http://www.fmadirect.com/detail.htm?item=2116§ion=45) from FMA Direct a few days ago. Seems foolproof and versatile enough for my charging needs.

bjett80 - I thought I did a good job of preflight and checked all the screws and bolts. I found a few loose and got those tight. I missed the tail rotor grips altogether though. Good thing that rotor missed you.

My first flight had my adrenaline pumping. The Falcon is a totally different experience than trying to fly my Rotofly. After charging the battery and checking it witht a voltmeter, it was close enough to 12.0v, I mounted it to the frame and balanced out the heli with the trainer gear attached.

The head speed on the rotor was intimidating compared to the micro I practice with but I got it to stay hovering 2-3 feet within an 8 ft area. The tail tracked well but there is still some drift that I have to finetune. Looks like I'll be searching back a few posts for the fine tuning instructions.

Can't wait for the battery to charge again!

So on the C , like 10C or 12C , does it mean the capacity or like what poiyt say the burst?( i dont quite comprehend this but i would like to know more if someone can explain more to me)..... there is so much to learn even on the batteries alone. but i'm loving it.

How would you always recommend to charge the battery? calculate it with how many C? whats the rule of thumb? and is the charger i bought better or should i be better off with what poiyt bought from hobbico?

poiyt: thanks for the heads up , i will test if it is alright or not tmr , charging the re-chargebles for the tx . and the cable does work on the mic port for the fms.


btmouse: so u used the wall charger despite the lack of an indicator? i didnt even dare try as i've seen so many lipos explosion

Status: offline 		Flight # 2 and charger info

I'm happy to report the second flight of my Falcon was accomplished without any vital parts departing at high speed from the heli.

Having fixed the tail wing grip (I need to get some of that blue loctite today), charging the battery and cleaning the garage, I fired up the Falcon for the second time. Btmouse said it best, the head speed is intimidating ! After warming up with a few short hovers and promptly setting it down when it left the "box", I managed a couple of 30 second hovers without incident.

I noticed though .... while the Falcon was performing fine, tension had me stiff as a board. I was definitely "in the zone", but from fear rather than ability. So, quitting while I was ahead, I shut down the Falcon and pulled out my Honeybee FP for some fun (and relaxing) flying.

I ran a few test on this new LED-less charger. This is a voltage regulated charger ... so it appears to be both voltage and current limited. The voltage is set at 12.60 volts regardless of load ... you can check the voltage with no battery attached and it will be 12.60 volts. The current rating is 1 amp. For a 1300mah battery, this would be a charge rate of 0.77C (1000/1300) - above the battery recommended charge of 0.5C but below the common acceptable charge rate of 1C.

In any event, I don't see an overcharge danger here. Maximum voltage on a fully charged lipoly cell is 4.23 volts ... for a 3 cell that would be 12.69, and the charger current will be at zero well below that at 12.60 volts. I just did a current test...with the battery at 12.55 volts, the current was 29ma, giving a charge rate of 0.022C.

Since current is a function of the voltage difference between the charger and battery along with the internal resistance of the battery and charger , at 12.60 for the charger and 12.55 for the battery, that gives an internal resistance of (12.60-12.55)/0.029 or 1.72 ohms. So the battery would have to be discharged to 10.88 volts to even hit the 1 amp charge rate, and I bet the charge rate decreases in a linear fashion from 10.88 up to 12.60.

If I ever discharge my batteries below 10.88 volts I'll do a current test and see if there is a current limiter in the circuit.

Happy Flying,

Barry


-evoIX .... a quick and dirty explanation of the "C" number. C for any battery is the current it can provide during a 1 hour period, so a 1300mah battery should provide 1300 milliamps for 1 hour and the "C" number represents the 1300ma. If the battery is rated for a 10C discharge rate, that would be 10*1300ma or 13 amps. A 0.5C charge rate would be 0.5 * 1300 or 650 ma. I believe the rule of thumb though is that a 1C (1300ma) charge rate is acceptable.

Of course, if you discharge a 1300mah battery at 10C, it should only last for 6 minutes .... since 13 amps * 6 minutes (13000ma * (1hr/10)) = 1300mah. In a perfect world, charging at 1C should only take 1 hour .... but like the Falcon charger, the charge rate decreases as the battery voltage increases, and I expect a 2 to 3 hour charge is more likely.

Hope this helps.



YIKES .... I just saw where Toshiba will be producing a lithium ion battery that charges at 60C ! That means 1 minute for a full charge. The prototype is only 600mah, but it's just a matter of time till they scale up.

Status: offline 		bjett80 that was a great explanation of "C" and how a lipoly charger works! As far as chargers go most of them are perfectly acceptable to use, some have more bells buttons and whistles but they all basically work the same. I'm glad you guys got your Falcons and are having fun with them. The head speed on these little helis is intimidating at first especially if your flying in a small space!
I know the pucker factor really goes up for the first several flights until you are comfortable with the Falcon but just wait, once you are comfortable and get out in a place that has lots of room it's defiantly awesome!!
Art-Tech must have changed their chargers since it seems lots of folks are getting the one without and LED. Glad btjett80 cleared up the mystery on that one!

Thanks for taking the time to check out the falcon kit charger. I feel more comfortable now using the charger. Art-Tech should have kept the earlier style chargers or at lease made a comment about the newer LED-less chargers in the manual they are shipping with the Falcon.

When I charged the battery for the second time I monitored the battery charge using a volt meter. The battery charged quickly up to ~10.9v and started to slow down.

evoIX - I charged the battery but kept checking the charge on the individual cells with a digital volt meter. I not exactly for certain but the 4 pin connectors will show individual cell charge if you put your meter on adjacent pins. You will get total charge if you place your meter to the corresponding red/black wire pair.

Back at work again, so I can't wait to get home and my second flight in. Definetly need more flying room than my garage until I get this trimmed out and comfortable with it.

I might even get my son to take some video so I can have a record of the first couple of flights as a newbie. It should be interesting to see a later video after 50 flights in on this bird.

The connectors are just standard Dean's Connectors (or equivilant) like these Connectors.

Status: offline 		ok, my falcon had a wee accident
i broke the tail boom which is easily fixed but i notice that the base of the swashplate is now oscilating.
would this indicate a bent main shaft.
anyone changed a main shaft on a falcon yet?

My Falcon battery has a deans connector and a balance connector.

BTW- the ESC has a 2 prong male connector sticking out of it that doesn't go anywhere. Any idea what it is ?
