Are you sure it's a WH G202? Neither the bouncing nor tip stalls are part of the normal behavior.

When I land mine I normally just let it glide in at idle. Let it descend on its own, if it seems like it wants to float it might be a touch tail heavy. It should establish a pretty good glide slope on its own.

At about 10 feet I put in a touch of up elevator to flatten it out, then let it come down to about 1 foot high and feed in elevator to hold that altitude, when it quits flying it should just set down on the gear.

Your description sound like it would benefit from a more forward CG. The ZDZ80 is very light which makes it harder to get the proper CG.
