Just a small report here, RCS on the Viper needs to be balanced. It is nearly undockable as is. The ports on the nose are way too strong, and it is impossible to translate up while maintaining a specific orientation. It actually adds downwards velocity while trying to translate up. As a workaround, I just disabled its RCS and added my own ports, it works just fine that way. An integrated docking port or a node for attaching one would be awesome too, for the time being I stuck a Jr port in between the engines. I have found some other issues but they've all been mentioned, just thought I'd add this one since I haven't seen it discussed. Great mod overall, awesome models, keep up the good work!
