I've been doing some research on Scaled Composites, the SS1 and the SS2 (Virgin GALACTIC) and I just HAD to make the SS2! Initially, I wanted to work on the SS1 but as it's already in FG (not a good one though, I wasn't able to get it over 120000 ft - it's supposed to go uptil 320000! and it's feathering doesn't work at all!) I decided to go for the SS2... I think that looks pretty "sexy" (as Richard Branson says) too, it'd be cool.
Well, as for the systems, I need to do a little more research on FG JSBSim rocket engines, changing wing positions (that shouldn't be difficult, I just need to find out exactly what happens when you feather, and use the feather-norm as a product in the elements in the fcs. Another thing is, I wanted to make the White Knight 2 separately so that MP pilots can carry you upto 55000 ft and release.
@Thorsten, is it possible to go past 150 km altitude now? Last time I tried with the vostok (AFTER removing the nasal warning script) a couple of variables became NaN and my laptop got stuck...
Anyway, I've started working on the model. I'll get back to this aircraft as soon as I make tutorials for the new ATR 72-500(C)
