Skytech m1 hurricane gyro helicopter
You ever find a fix for this problem?
I've got one too and I just noticed that the "green" charging light isn't coming on when it's plugged in to charge. I got the copter "used" and it apparently had a full charge when I got it home, but after using it and putting it on the charger over night, nothing. Reading the manual a little closer this morning, I noticed the "green" light is the "charging circuit: on" indicator. It's not coming on at all. (No, there are no switches etc.)
Here's what I'm going to do.
(Since we're dealing with Li-ion batteries, extreme care must be taken. Possible fire hazard. Follow these steps at your own risk. I am not responsible for any personal injury, or damage to your helicopter.)
THAT SAID! :)
The unit uses 3 wires to supply power coming from the charger.
One is for power (+), one is ground (-), and the other would be for the charging circuit (+).
Now, the reason for the above warning is because with any charging system, there runs the risk of fire, explosion, or acid leakage when improper charging techniques are applied. Li-ion batteries more susceptible to this type of damage than traditional Ni-Cad batteries, but that doesn't mean you can't recharge them yourself if you're careful. (Be warned, you may decrease the life of your batteries this way, but then again, what does it matter if you can't fly the darn thing anyway right?)
Okay. The charger's transformer (the part that goes into the wall) states that it pushes 5.6v @ 80mA into the batteries when plugged in. (Read: "Output" on the transformer.)
Since there is no additional output voltage listed, we can assume that this is the maximum listed amount of voltage and amperage that any one part of the system can handle at a given time.
Besides, the lower and slower you charge, the safer and better charge you'll get.
If you have a multi-meter handy you can do a voltage check on the wires to verify that your current transformer is putting out the correct voltage, but my guess is that like mine, it is not. (Most likely on the "Grey" colored lead.) Then check the voltages at the leads from the helicopter. (This tells you how much battery charge you have.)
That said, you have a couple options.
1. Use the transformer you have.
2. Find and use another.
Now we have to do something a little drastic here first. Unless you have a connector that fits the helicopter's connector (Check an old computer for one) you are going to have to take that little charging box apart and remove the one that's in there.
I don't suggest trying to splice directly into the wires of the helicopter as there is nothing wrong from the connector back to the helicopter. (If it ain't broke, don't fix it.)
Once you have this piece, follow the suggestions below.
1A. Using the one you have. - Since we know the "Red" wire and "Black" wires on your unit work, (indicated by the Red light you mentioned) you could simply splice the third "Grey" and the "Red" wires together PRIOR to the connector leading to the helicopter. This would divert power from the "Red" (power) circuit to the "Grey" (charging circuit) thus supplying power to the charging circuit. Now this will bypass the part of the circuit board that stabilizes the current in such a way that is safe for Li-ion batteries, but then again, most of these fixes are going to do this anyway.
2.A Find and use a different transformer. - Cell phones typically charge at around 4.3v to 5.6v. The power cords used to charge these devices can be found just about anywhere. USB ports charge at 5.6v as well.
Knowing this, you should be able to find a working transformer easy enough simply laying around the house. (Verify this by reading the "output" of the transformer you wish to use.)
Then, take the Black (-) lead and splice it into the Black lead of the connector (male) that is going to plug into the female connector of the helicopter.
Next, take the positive lead from the transformer and splice it into both of the other leads (Red/Grey) of the same connector.
Check your voltage output of all three connections. You should have positive voltage at both the Red and Grey leads, when the negative is touched.
Take a reading with your meter from the helicopter and write it down.
Assuming that you've done this correctly, find a well ventilated, fire resistant area to charge the helicopter and plug it into the female connector of the helicopter.
Watch the whole thing closely to make sure it doesn't catch fire and leave it alone for a bit.
After about an hour, re-check the voltage from the helicopter. If you notice an increase in the voltage here, you are charging your helicopter's batteries.
Continue charging until you reach the maximum votage of your battery pack. About 6v. (I think this battery pack is most likely a 6v setup.)
Once you have reached full charge, disconnect the charging unit from the helicopter and fly your bird! :) Repeat
Just to let you know. You can (if you don't go much higher) increase the output VOLTAGE of your transformer SLIGHTLY in order to decrease the charging time necessary to recharge your batteries.
There. We're done.
Let me know if this helps at all okay? I'd like to know how it all turns out for you.
Oh! Now that you've got a little info on how your bird works, it may be time to boost your birds power all around! lol But I digress.
Hope this all helps!
Any questions, post them here and I'll get back to you as soon as I read it.
