As a professional helicopter flier, I often find myself writing reviews for remove control helicopters, and this includes electric helicopters. The electric ones are often the ones with the most agility, which is very important to many consumers, but you can probably imagine that these helicopters are also the ones that can be dangerous if you try to fly them in the rain or near power lines. So whenever I write reviews for remote control electric helicopters, I make sure to emphasize the potential pitfalls and I test each one carefully.
