View Problem

[CAFedm]

I've added a physical landing light part to an aircraft, using a fairly large triangular piece. It all works fine, but now the aircraft appears to the sim to be twice as large as it really is. Upon loading the airplane, it appears very small in the selection window of FSX - no prob there, but then when the sim loads initially, it also appears very small (as if zoomed way out). Zooming in adversely affects how lighting and afterburners appear. Only upon  reloading the flight, does everything display normally. Wondering if there may be a way around this, or if anyone else has noticed a similar problem - it's not major but rather annoying.
