you didnt say if you have the flaps intalled. if so remove them and that will take alot of lift out. if you leave the flaps on you will have to give it down elevator trim. if you dont have the flaps on still need down elevator trim. just remember if you do have the flaps on and trim it. you will need to retrim the plane when you remove the flaps. cuz if not you will have to much down trim and the plane will be very difficult to fly.
