Well BAS and I have Hurricanes...he has the earlier version and I have the new version wuth the pretty paint scheme.....Also we both have FPE 2.4 's in them....he is going to send his engine in and get the update on it with the new ignition..I'll send my later and do the same thing..believe this might give the engine more power and prehaps make it do 3-D maneuvers a little better.....I put everything ahead of the CG,except for the rudder and elavator servos,and I didn't have to add any ballast..it's a great flying plane....I like it better than my Laser 2000,made by the same outfit.....Try it,you'll like it....................
