Default Richmodel Yak 54 -40

Hi All,
I have baught a Richmodel Yak 54 -40 and will be using an elec motor.
The destructions are a bit vague around attaching the motor mount.
I have included photo's of the motor attached, its pointing slighty up and to the right- is that right -or should it be point to the left and down?

Off the top of my head, you should want down and to the right. You want right thrust in the motor to overcome the torque from the spinning motor and down thrust to help prevent the ballooning (nose of the plane pops up) when power is applied during a flight. (Ballooning is not to be confused with porpoising which is when your planes nose pops up and then down continually during level flight. Porpoising is caused by a plane being tail heavy).

However I am unfamiliar with your specific plane, so it might be different.
