Review: Awesome little plane. From super slow flying to crazy 3D aerobatics, it does it all! - Very very fun. For the money, it is an incredible plane. It can fly extremely slow or extremely fast, it can handle some wind, it is very durable. The light kit is awesome too, dont forget to make one of the switches on your transmitter change the colors of the LEDs, there is a very bright setting that is much better than the others. The one thing that is a bummer is that putting the props on you have to be careful... I suggest watching a youtube video. Get this plane!
Review: liegt für die kleine Spannweite erstaunlich ruhig in der Luft - Das winzige Flugzeug liegt erstaunlich ruhig in der Luft und macht viel Spass, es ist sehr robust und somit ein idealer Urlaubsbegleiter da es nur sehr wenig Platz benötigt, am besten in der Original Verpackung. Ein wenig Flugerfahrung sollte man haben.
