Well, after installing the 46FX in my Pizzaz I found the performance to be lackluster. No authority in any manuvers and the plane wasn't as crisp as it was with the 72 in it. The 72 in the CAP was GREAT! I flew it for the first time today and had a lot of fun. I can't believe that I never had a 4 stroke until a few months ago... I don't know if I will ever put a 2 stroke in a 40-90 size plane again. Big difference! Now I need another 4 stroke for my pizzaz, maybe a Saito 100
