I would watch the weight adding unless you are sure it is nose heavy as this plane has issues with balancing, most owners have moved there balance point forward of the factory recomended position.

You do have to fly this plane in as it does not "float". You should be able to control airspeed with elevator and alttitude with the throttle. I bring mine in on final at idle, as I lose the last of my alttitude, and slowly add up elevator to get the nose up and slow it down, when it starts to flatten out "stall", add a little throttle but the keep the elevator at the current position. this should get you on a decent approach? use the throttle to control the glide pathe and when the plane approaches the ground, cut the throttle to put her down.

I have noticed this plane has a pretty fast descent rate and it can cause you to get a little nervous as it nears the ground, causing the application of up elevator which causes what little stall the plane has and your "bounce". It then picks up enough airspeed and ground effect to regain flight. remember the plane is moving forward at a descent clip and what is perceived, from the front, as to fast of a descent may be just about right.
