Hi there, just looking for input as to the plus and negatives of these three planes. I love all types of 3D and aerobatic style flying. Prefer 3D stuff. Which one is most suitable for 3D, like harriers etc. I have been reading that a Yak is best for slow 3D stuff and an extra is better for IMAC. Any facts or people with hands on experience with all these planes?? Thanks for your thoughts!
