Hi, i'm a beginner with q-500 (424) in venezuela south america, have a viper and whant to built a new fuselage, i know that some fuselage have better desing than others, and also you can make some legal mods to it, changing the v tail degree and incidence, and the distance between engine backplate and wing leading edge, which is the best fuse and configuration or modifications you can make to it, thanks.
