RE: Is my a123 battery dead?
Thanks to everyone that replied. Capt. I'm using the hyperion eos1210i with the lba10 balancer. Yes I found out that my battery is still good. I just had to apply voltage to it to bring it back up so that my charger could charge it. What I did was just zap it with 12v from an ac adaptor until the voltage came back up. I wish the hyperion had an adustable voltage cutoff level so that the battery didn't have to be at least 3v before the charger wiill charge it. It's somehwat of an inconvenience having to charge it as a nimh or nicad pack just to bring up the voltage to the point that I can switch over to 123 charge mode. Thanks again.

Is my a123 battery dead?
How can I tell if my a123 cell is dead? I have a unused cell that is reading .3 volts. I put together a 4s and tried to charge but got error on two different hyperion balance adaptors. I checked and found that one cell is only reading .3 volts. That cell was never charged before. The other 3 was previously a 3s pack. So far I love a123 cells because of there rapid charge rate. But I hope they come out with lighter, faster charge rate and higher capacity cells soon.

RE: A123Racing Charger Questions
Hello Brian, I wanted to know if the sonic charger is already cabable of charging a 4 s pack? I opened up my sonic charger and examined the sensor connector and it looks like the middle pin is connected to the circuit. If the only problem is a thermal one I could easily just run a fan on it to keep it cool under the heavier load. I know that I would be doing that at my own risk and void the warranty obviously. I just wanted to know if it would be possible or would it definitely not work or damage the charger. Thanks

RE: Cybercopter
It's possible to modify the cybercopter to increase negative pitch travel by simple modifications to the linkages. I'm still working on it. Its quite easy to do actually. I will post a pic when I got it working.

RE: Cybercopter
I just got my cyber copter off ebay for under $200. Its a very well built helicopter and is a good design. However they have to watch their quality control because mine has some tolerance problems that caused severe binding in the head assembly, I had to correct this by filing down certain parts to loosen it up. Also the screws as was mentioned strip to easily.. just backing them out its possible to strip if it was tightned to much in the first place during assembly at the factory. In my opinion this heli is in a class by itself. I have a hornet and a feda model.. these cannot compare to this helicopter in terms of strength and design. However all this comes at the price of weight. Over all this is a very impressive helicopter for the money.. considering that just the swashplate alone being made of aluminum would cost close to $80 on the other helis of this class.

2 long
it seemed like a long time..but actually converting it to cp is not that difficult.. All you need is another rotor head and a steel 2 mm shaft from an electric motor.. four 2 mm bearings and 2 collars with set screws. The Difficult thing is getting it to fly! :)

Wait till you see my heli.. you will know why I use my nick. As far as robustness in a crash.. i would think a crash of a cp head would cause more damage since it is connected directly to the swashplate. But I haven't had the opportunity yet to see since i can barely get it off the ground.. I think its something to do with the blades not being perfectly balanced and tracking perfectly. I found when i was flying the feda that if you make the flybar paddles at 45 degree angles that it makes it a lot more stable in hover.

I'm doing the conversion for my own challenge.. economically its not really worthwhile to do. I still haven't got it stable yet and I've been trying for many hours. But I have learned from flying the fixed pitch feda that the blade pitch is very important.. everything has to be right on or it just won't fly. Collective pitch flybarless is very difficult to get to fly well... although it has been done on the hornet successfully. I will post a pic of my heli soon whether i get it to fly or not.

cp conversion
I completed converting the feda to cp.. but still trying to get it off the ground.. thinking of using a brushless motor for the tail to get rid of the unrealiable brushed motor. Will post some pics when it flies...hopefully

working on cp for the dragonfly
I'm trying to convert my feda heli to cp by using and modifiying the stock parts. If it works I will post some pics. This is one damn expensive but fun hobby!
