Looking for input on an idea... shuttlecraft: feasible?

[inigma]

I wanted to post in General Discussion about the feasibility of such little spacecraft, and I know not very many people here check out the Rocket Builders forum, so I thought I'd post a plug here to see if we could get some feedback:

We've been trying to get this thing into orbit in .21. It's the SSI Shuttlecraft Type 1 Protoype 2.1. Has anyone else designed such craft before? Do you have a shuttlecraft-like sport spaceplane you've developed that might look similar? If so, are you interested in helping out or submitting new ideas for this project? We'd love your feedback, and any comments of those who might be able to lend a hand with testing, or providing support.
