I am going to guess that is too much prop. For 50cc sized engines, there are 2 prop sizes that are standard. 22-10 for speed, and 23-8 for aerobatics. Generally the 22-10 is what is used. A twin configuration generally has slightly less power than a single. Then generally you go down one inch in diameter when going to 3-blade. So, going by this, you would be looking at a 20" or 21" x10 3 blade.
