I fly a .60 sized plane and I was having the same problem. I thought I had tried everything, I was using flaperons, I killed the engine, it just kept landing hot. Then an old buddy Bryan Hebert recommended spoilers instead of flaperons, just reverse them. I did. The next flight the plane came in nice and smooth at a perfect AOA, and I would be surprised if it was going 10 MPH when it touched down. I've even had to land it gear-up before due to a malfunction... it was going so slow it caused no damage whatsoever, I even had a guy holler from the pits that if he knew the plane would fly that slow he would have gone out there and cought it for me... And ignore the person who thinks you need to just jump into a .90-sized plane right away, a .40 or .60 plane will get you through Intermediate.
