Customer Reviews

I bought this battery to carry out some experiments with raising my flying time. This worked great. I now typical about 15-16 minutes flying time, and that is just till is begins to get a small weak. I could easily go one more couple of minutes, but I don't want to push the batteries that challenging, and it is a lot much more fun flying with charged batteries.
This modification is secure and very easy. This is considering these cells use safety circuits to limit over discharge and more than charge. There are a couple of precautions even though:
1. Use two batteries of equal age. This signifies a new battery in a new heli and a new replacement battery, or two new replacement batteries. Do not mix a new replacement battery with an old, worn out battery.
two. Use two batteries of equal charge - preferably discharged. This is not essential, but it is greater to commence with two discharged batteries so they don't have any significant power if you accidentally short some thing. Also, it just keeps every little thing in greater balance from the commence.
3. Hook up the batteries in parallel - red to red and black to black. This doubles the battery capacity and increases the flying time. If you hook them up in series (end to end), you will double the voltage, which will burn out the motors if it doesn't fry the heli's circuit board (and you will not be able to charge them anyway).
This is how you make the modification. First, the new battery is probably totally discharged, so fly your heli until the battery is discharged (unless you are working with two new cells). Then splice the new battery in parallel with the battery in the heli. I discovered it easiest to just cut out the existing battery, leaving about equal lengths of red and black wire. Then I trimmed the wires on the new battery to the very same length. I then stripped and tinned all the wire ends. I then soldered the two batteries together, red to red and black to black. Applying the double sided tape that held in the old battery, I stuck them together. I then slid some heat shrink more than the wires coming from the heli. I then lap soldered the battery wires to the heli wires, red to red and black to black. I then slid up the heat shrink over the solder joint and shrunk it. You could also wrap the wires together and cover them with tape, but that is likely tougher in the limited space, and they will not hold as well as solder. Then I removed the weight taped in the nose of the canopy. Lastly, you just locate the battery over the battery holder (see photo) and slide on the canopy - it's a snug fit, so there is no need to have to tape down the battery.
With this basic modification, you will double your flying time - or extra. Every battery has half the present getting drawn from it, so they preserve a greater voltage for a longer time. It really is like the to begin with minute or two with a single battery, but for 10-12 minutes. Depending on how challenging you fly, even right after 14-15 minutes, you can still fly up to the ceiling. Right after about 15-16 minutes, I start out to notice that the heli is losing trim and it is harder to sustain lift. I could easily keep going one other couple of minutes, even flying in ground effect, but why push the batteries that hard. The down side is that it would in all probability take 3 hours to recharge working with the USB cable charger. So instead, I am using the wall plug charger that takes about 1.five hours or much less to fully charge the battery. The heli is also a tiny nose heavy, but I like that, and several individuals add nose weights anyway. With the heavy nose, you generally have forward momentum, and I consider it's simpler to control. You can also go actually rapid in the forward direction, but especially slow backwards and you cannot seriously hover. You can also add counter weights to the tail (like the weight from the nose) if you do not like it.
Some other notes on battery life:
1. I estimate that the heli draws about 1.2A to preserve altitude.
2. Full throttle draws about 1.5A max with a totally charged battery, but ordinarily about 1.35-1.4A.
three. Running the tail motor draws one other .two-.25A.
four. The LED only draws about 12mA, or only 1% of your typical existing.
So you see, if you just maintain altitude, drift forward, and only turn right and left, you only draw abut 1.2A. But if you are continuously zipping up and down and forward and backward, you are drawing about 1.65A. I'm in all probability somewhere in the middle and I get a excellent 15-16 minutes. Your outcomes could vary.

Instead of soldering, just cut the lines that go to the battery currently in spot about halway along, and just strip a small element and wrap the bare wire around the new batteries exposed wires and wrap in tape. No soldering essential. 15 minutes max.
