Ok, I got my axe cp 2.4 about a month ago but probably only have 10 battery cycles through it just due to life getting in the way.

Question 1: Ever since I got it, the tail rotor motor makes this terrible low toned squeal noise when it rotates, kinda like a seal bark actually. It seems to work but might be a bit jittery and is just plain annoying to hear when flying!

Question 2: The wall charger is taking 1.5 hours to charge my drained battery. Does a nicer lipo charger charge faster or just have more features? If it is safe to charge it faster than the wall charger, are there any cheap options out there for under $30 to $40?

Thanks a ton!
