Thanks for your reply Robotech. That's more information than I had before! I should have also included in my post that I am interested in a 40 size P51. I think the H9 P51 is a 60 size if I'm not mistaken?

Also....I did use the search feature here and found some input to this question by another modeler. It appears that in the 40 size the popular one is the World Models P51. I'm curious to know also if anyone has knowledge of the Model Tech P51 ARF? Are they good or bad and why?

Thanks all.
