Question 1

What would happen if I used a 1S 25C battery to replace the 20C battery for the helicopter? It's a different li-po battery with 3.7 volts.

Accepted Answer

No issue, more punch. I have a 45C in mine. Flight times not as long but it moves quick.

Question 2

So you know if I buy two helicopters if I can change the channel they are on so I can fly them together or will they crash when I try to fly them?

Accepted Answer

i dont think you can  you can bind two heli on the new syma s107  that are different chanel  but you cant change chanel change the  board for new chanel they will fly in sync  just space them apart

Question 3

Is the battery on board the helicopter replaceable?

Accepted Answer

It is replaceable, but it requires some skills and knowledge. You'll need a mini Philip screw driver a way to strip the rubber from the wires. I recommend using electrical tape and not scotch tape to seal the wires together when you get a new battery. I recommend buying "10 pairs JST Plug Connector RC Lipo Battery Male/Female" and connecting the wires to these, so the battery can easily be replaced each time it begins to stop holding a charge. Also, if you strip the yellow cable and connect it with a female connection, you'll be able to charge the battery MUCH quicker then if you would the normal way. I'm talking 5-10 minutes instead of 30 minutes. The yellow cable will still work the same with knowing when to stop charging. Plus you can use other r/c li-po batteries that uses 3.7 volt, but because the manufacturer is different, the quality can be so much better!

Question 4

is it for outdoors?

Accepted Answer

I also flew mine outdoors, on a calm night. So dark, I could only see the flashing LED's. I was amazed how high it would climb. Once it reached a certain height, I didn't seem to have much control of it. The slightest breeze would send it into the neighbors yard. It may seem odd, but I think the sun light affects the controls. During the day, I'm lucky if I can get it 2 feet off the ground for no more than a few seconds.
