I just purchased the new Phoenix Extra 300s .46 size GP/EP arf. Most of the Phoenix arfs have been completely redesigned lately and I must say that I am very impressed with the newer versions of these models. The new extra has a much more scale outline than the older version with airfoiled tail feathers and the quality looks good. On this build I will be going for all out lightness so I will be using a 460mah 7.4v lipo with a mini reg and I will also be going with mini servos. I have 3 engines to choose from .52 surpass @ 15.5oz .70 surpass @ 21oz or a ys .63fzs @ 18oz but I am leaning towards the YS as it has the most power per oz but it would be interesting to see what the little .52 surpass could do with an all up weight of about 4 1/2 lbs. If anyone else is building the new extra I would like to see pics of the build.
