7asp where are you in your skill level in flying? A 1.60 is a monster glow engine and goes on a large plane generally for an advanced flyer. Also, since you are wanting to go with an inverted mount I am guessing that the plane is scale or an acrobatic plane and not a trainer or beginner type aircraft.

Not trying to criticise, but would hate to see you lose an expensive plane and engine or do some serious damage with an engine size that is not generally one newbies start with.
