I recently completed a refurb on a 96" Ikon West Monocoupe. For reasons still unknown to me I decided to install flaps. On the second flight I decided to drop the flaps to see what would happen ( I was at a safe altitude), to my suprise the nose dropped.I have tried it several times in different wind conditions with no change in results. Is it possible this is the result of the plane being nose heavy?
Any thoughts on the subject would be greatly appreciated.

Thanks and regards
