Status: offline 		Ya! I'm glad I was able to get it back. I had the visa ready to jump outta my wallet for a BL setup for the tail. Or at the very least a DD from GWS. We'll see how it goes. If this motor wears out quickly it is waiting with baited breath to pounce on upgrades. It's got a mind of it's own sometimes

Thanks for the encouragment. Hope the wind dies. I was jealous of your outdoor fun this morning. I gotta get out there so I can crash and go through all this again[)]

They are a little more expensive than the stocker, not much just a couple of bucks, but 16 flights verses 100 flights definately covers the price difference. When properly broken in you can't beat these motors.

Short Filght, not to worry about giving Robo credit for the Century recommendation. It's all good bro! I am glad the motors are working out good for you.

And make sure your batts. are good. I purchased some of the DX cheapies which wouldn't hold the bird in the air for more than a few seconds.

Too bad that you had bad luck with the DX batteries. I purchased 2 of the Mystery 900mAH 7.4v lipos from them in January and have had trouble-free operation with them so far ...


Yup, bought 2 Mysteries and both had the same problem. Would charge them up and get maybe 30 seconds of flight, then they would quickly lose power and drop my bird to the ground. I'd wait a few seconds, get back up in the air for a few more seconds and then back on the ground. Ended up with 2 very nice JST plugs for about $18.00 .

Hey nice flying Broggyr. I've only been able to get outside with my falcon 3 times so far and couldn't manage to hold hover in the lightest breeze. 1 cracked frame and 1 cracked core. Lots more practice...

I have been doing some thinking

Oh, that can't be good...

I'm making the following asumption about the pot. It is an adjustment for the tail only. I assume the the pot has no effect on the main as I don't notice any changes to the main during adjustments. So I figure that it directly controls how much voltage is fed to the tail thus managing tail speed vs the constant of the main. Please correct me if this assumption is faulty.

Yes, the pot is only for the tail, but it doesn't control it directly. The pot acts as a voltage divider and the 0-3.3V is input into an analog to digital (A/D) pin on the microcontroller on the board.

What I need to know is where on the 4-1 sould I place the +,- contacts of my meter to check the voltage output of the pot. In this way I figure I can set it up without all the trial and error which isn't getting me anywhere currently.

Status: offline 		hi i used to post here all the time but had moved. well i am here to say that i have a falcon 40 and am parting it out now. i am selling everything for cash. I have
-A custom made metal rotor head core that i payed $40 for and it will never break
-Two sets of main props
-two servo's
-one 4 in 1 rx
-two cf tail rods
-super skids(not original but the copy of it payed $20)
-original skids
-main motor
-main frame
-taill prop and motor

ok i am parting a fully rtf helicopter so if i missed anything that comes with it its here. I will give good deals for this stuff and will sell the whole heli at a discount. There is no tx!
If you want to buy any of this stuff pm me and ill be happy to discuss prices. I will ship but will charge only what it costs me. thanks

You invest so much money in a r/c heli. Why not just buy the real one.

I just upgraded to Li-Po batteries, and was wondering, which way is best to leave the batteries overnight? Should they be left in a dischargeed state or should they be fully charged.
These things are not cheap, so I want to be sure to get the best life out of them I can.
Thanks
Have A Great Day

Status: offline 		if i am thinking right these batteries should be charged back up as soon as possible.. just give them time to COMPLETLY cool down.. once the voltage drops so low it can damage the cells in the battery.. i do not leave mine unattended while charging, so if i can get them on the charger for at least 10-20 minutes that will get the voltage to a safe level in my opinion, and then i can finish charging them later when i have time to be around while they are charging.. hope that makes sense..

I always charge mine up ASAP as sheer said. I let them cool off and get them charged. They shoud not be charged unattended however. If you have doubts about this go to youtube and search lipo fires and see for yourself. They don't just burn they explode so safety first. If you cannot charge them right away I would take sheer's advice again and put them on to charge for a short time to get the voltage up to safe levels. It is said that if they are going to be stored for a period of time (ie you're going out of town for a week and cannot take your heli ) they should be charged to half capicity for long term storage.

Be safe and enjoy your new batteries. Despite the stability downfalls they are fantastic power sorces.

lipos can be damaged if they drop below 3V per cell (so 6V for a 2S and 9V for a 3S). lipos also have a good shelf life...
I have a 3S, and my bird stops lifting off the ground at 10.5V. I have left it like that for days before I charge it up again (it's still well above 9V)

If you going to fly every couple of days, I wouldn't think it would matter if you left them discharged (as long as they are above 3V/cell) or if you charge them. But as sheerider and UTM say, if you're going to charge it back up again, let it cool down first.

I wonder why "they" say charge it to 1/2 capacity? I would think that fully charged would give you a longer self life...
