TY Model Black Flyer V2 Carbon Fiber Film RC Airplane With Power System
A part of the review has been auto-translated.
I've built and flown all of the Black Flyers: V1, V1.1 and V2. The V1 Is an excellent flyer, but the packaging means that some of the carbon can be broken in the post. The V1.1 and the V2 have improved packaging and a better wing fixing. The V1.1 is very similar to the V1 buthas an increased wing chord giving more wing area. Getting to the V2, it goes together well but, like the V1.1 it has a flat plate wing(s) which require great care in covering to avoid warping. It also means that the lack of wing section combined with the all flying tailplane means that the elevator is very sensitive and trim is critical. Both the V1.1 and V2 have a tendency to 'tuck' and dive into the ground. I feel that this is a design fault and they should have retained the cambered wing. On a value for money basis, you can't beat any of them. Weights with battery: V1 13.5 gm, V1.1 18 gm, V2 18 gm. All covered with tissue, not the supplied film.
Very good and easy to build indoor flyers. The biggest challenge are the tiny components in particular the area fixing screws. The flight behaviour of the finished flyer is impeccable. With 1S 160mAh, the lightweight brings just 23g to the scale. The engine also has sufficient power and it is possible to loop on the smallest radius. The centre of gravity fits and long flight times are feasible.
