A more realistic version of the Twist 40. Flying weight adjusted to the true Twist, as well as thrust to weight ratio. I have the Twist 40 PnP, and the stock is just way too overpowered. In real life, the Twist struggles to hover even at full throttle with the Evolution .46. Also, on knife edge, there is a lot of roll coupling and the plane tends to roll into itself on knife edges. A rudder to aileron mixing was included to reflect this.
