RE: 108
Doug,
For the flap servos, install them both the same way round ( i.e. lay them both on the left or right hand side), not mirror image as you would for the ailerons, that way they move in the same direction.
Yes the head of my motor does stick out (not by much though) I mounted it 45 degrees off the inverted postion so the head is at about 7 o'clock (looking from the front) where the cowl is widest. The silencer exits under the cowl.
Hope you enjoy the model, experiment landing without flaps it seems to reduce the bounce.
Simon.
