The Zoopa is for me one of the best coaxial helicopters in Germany. Then even delivery via Amazon Prime, spare parts available at all times and more recently by some versions also bodysuits (only helicopters) as a substitute. The new design with two LEDs is a blast, the whole Heli are again a lot of stylish. What else? If subsides after three days the desire because the Zoopa Although great flying, but bored, here Tuining tip. Remove everything that is unnecessary, in particular all of the support at the rear with the Finns, etc., to take the weight of the front of the hood and then a surprise- Koaxuial Heli is evil. He is then so fast that medium-sized rooms are very tight, making again for a few weeks mood. Conjures up even experienced pilots a smile on your face. The robustness remains, the fun increases. One of the handful of almost indestructible helicopters on the market, here a new look for very reasonable money. What's missing? Clearly a change of battery, then the Zoopa would an unconditional recommendation. So cool down and loading pauses and the desire to fly more easily. After tuning even conditionally suitable for outdoors! I recommend it for young children and people who are looking for simple ways of procurement as here at Amazon. Whoever still complained here, is to buy at retail, then he will see. Who wants to save the Coaxial Heli aria itself, incidentally, uses the same for WL V911 or its various counterparts. This is the best paddle 4CH helicopter in the market with replaceable battery for just about 30, at least in China Import. However, not suitable for children, but for children innsere just right, by the way flies also my wife with increasing enthusiasm. For all want to begin gentle Zoopa 150 and everything is fine !!
