Thank you all for your kind comments, as for the engine Alan i had no problums fitting it in the fuselage.
My biggest problum was fitting the underside of the fuselage, i had to cut off the locating pins as they did not line up with the pins on the cockpit section whitch i had already put in the fuselage, but this was my own fault as i built the floats with the underside section attached to them, i thought it would make life simpler.
Rather than trying to line up the two halfs of the fuselage plus the cockpit assembly and the underside float section all in one go.
To a degree this did work, but i had to use clamps till the glue had set.
