RE: Electric twin engine problem help!
Yes. Go to the hobby shop and get an in person run through and tutorial on batteries. You will catch your house on fire if you don't follow the basic rules of lipo charging.
Also, I would recommend teaming up with another electric RC guy so you will get the basics ironed out. The forums are OK to get details straightened out but if you have a lot of stuff that is not set up correctly to begin with the forums are going to be very frustrating. You can learn the basics much faster by having a guy run through it with you in person a few times.
