Weston Magnum - Engine Mounting?
i left the mount on the fire wall set the motor in then marked it
drilled and tapped for 4-40 then i took the mount out and heated a 4-40 blind nut and pulled it in the mount so far its worked fine the bottom of the plane is a little whimpy take a piece of ply and glue it on the bottom after a few rough landing i did break the nose ring i made a new one put it back and i pulled the covering back to the fire wall and fiber glassed the nose very tough now.
i would suggest you balance the plane slightly tail heavy thats how my nose got scruffed up in the beginning once you kill the motor no matter how much elevator throw you have you won't get that nose back up.
