Costumer Critiques

I purchased this battery to execute some experiments with escalating my flying time. This worked great. I now average about 15-16 minutes flying time, and that is just till is begins to get a tiny weak. I could easily go yet another couple of minutes, but I don't want to push the batteries that difficult, and it's a lot additional fun flying with charged batteries.

This modification is secure and uncomplicated. This is simply because these cells use safety circuits to limit more than discharge and more than charge. There are a few 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.

2. Use two batteries of equal charge - preferably discharged. This is not important, but it is far better to start out with two discharged batteries so they don't have any substantial power if you accidentally short one thing. Also, it just keeps everything in superior balance from the get started.

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 finish), you will double the voltage, which will burn out the motors if it doesn't fry the heli's circuit board (and you won't be in a position to charge them anyway).

This is how you make the modification. Initial, the new battery is almost certainly fully discharged, so fly your heli till the battery is discharged (unless you are making use of two new cells). Then splice the new battery in parallel with the battery in the heli. I found 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. Utilizing the double sided tape that held in the old battery, I stuck them together. I then slid some heat shrink over 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 quite possibly tougher in the limited space, and they won't hold as nicely as solder. Then I removed the weight taped in the nose of the canopy. Finally, you just locate the battery more than the battery holder (see photo) and slide on the canopy - it really is a snug fit, so there is no want to tape down the battery.

With this uncomplicated modification, you will double your flying time - or far more. Each battery has half the present being drawn from it, so they retain a greater voltage for a longer time. It really is like the 1st minute or two with a single battery, but for ten-12 minutes. Based on how difficult you fly, even soon after 14-15 minutes, you can nonetheless fly up to the ceiling. Following about 15-16 minutes, I start off to discover that the heli is losing trim and it is tougher to retain lift. I could quickly maintain going another couple of minutes, even flying in ground impact, but why push the batteries that challenging. The down side is that it would in all probability take 3 hours to recharge employing the USB cable charger. So rather, I'm working with the wall plug charger that takes about 1.five hours or much less to completely charge the battery. The heli is also a small nose heavy, but I like that, and many individuals add nose weights anyway. With the heavy nose, you often have forward momentum, and I believe it's much easier to manage. You can also go definitely rapid in the forward direction, but incredibly slow backwards and you cannot honestly 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 keep altitude.

2. Complete throttle draws about 1.5A max with a totally charged battery, but generally about 1.35-1.4A.

3. Running the tail motor draws yet another .two-.25A.

4. The LED only draws about 12mA, or only 1% of your typical existing.

So you see, if you just sustain altitude, drift forward, and only turn ideal and left, you only draw abut 1.2A. But if you are continually zipping up and down and forward and backward, you are drawing about 1.65A. I am probably somewhere in the middle and I get a fantastic 15-16 minutes. Your results may perhaps vary.

This was a replacement battery for a Syma 107 that had over 100 flights. Hope

the new one lasts as long. Crucial factor, with these batteries let them cool just before

and after charging.
