When you first by a R/C helicopter, it is fun, but you notice that it might be slow, the battery life may last a few minutes, and there might be that annoying spring that keeps the throttle down and won't let you hover. These few problems can be cured in a few steps, drastically improving the helicopter.
Notice that this helicopter may not be like yours. These mods are for the Syma S107G and they might be able to work on your helicopter. I am not responsible for any damages, voided warranties, etc. Please be careful when doing these mods. Make sure that you are very good at flying your helicopter the condition you received it in. These mods will make the helicopter harder to fly.
