Main engine substandard

The Blade mSR X is by no means a helicopter for beginners, newcomers from coax helicopters will have their difficulties at the beginning, especially in left-hand corners. The helicopter is by AS3X very quiet in the air, even in light winds. After a controller error, however, he does not go on in a stable hover.

Left turns always require dose Nick and Roll to a rapid uncontrolled drift of the helicopter after Linls avoid. The experienced helicopter pilot used to it quickly and then will be enthusiastic about the flight behavior on the whole. The beginner will be hard.

Weak point of the helicopter is clearly the engine. After about 30 flights is my kaputtgegangen. Unfortunately, this is not an isolated case, as you can see various model forums. Apparently there is a quality problem here. Unfortunately, you get current and nowhere spare engines.

Due to this lack quality and unavailability of spare engines, I can only awarded 2 stars.
