Martin and the Beta team have done an outstanding job. Its much more user friendly now thanks to the glass cockpit, no more key combinations to remember:). The Lv10 textures look outstanding, for a small performance hit. The scenario editor is amazing, you can add/delete ships and put them wherever you want.
With the release of orbiter 2006, I'm updating Walrus and Mystic. The issues with Mystic's re-entry problem has been fixed properly. I'd like both Walrus and Mystic to have compatibility with the new scenario editor, but unfortunately, I can't get it to work. I'll wait and see what Vinka or Martin says(or if someone figures out how to make spacecraft/multistage add-ons work with the new vessels folder) for now
I finished texturing the Wasp LV(no pics its on my other computer) it has the same color scheme as the Walrus LV, the weights and burn times, I have already figured out. Otherwise this add-on is complete, its just the issues with orbiter 2006 scenario editor compatibility holding it up
The lunar penguin, I haven't found a launch vehicle for it. I'd prefer a falcon 5, but I have no desire to make it since there are 3 others in development(a 4th one really isn't needed). So I'm just going to release it, with a lunar landing scenario
when all of the above is done I'll give details on my next orbiter project
