FWIW, I think the overall lines are really. really cool. It is too obscure (?) as a scale jet to get pumped enough to buy two engines or even two EDFs for. But it might be fun if re-worked as an original single engine "canopied" plane as opposed to a multi-engined "cabin" jet ? Of course, it seems you already have the current molds on hand!

As always, just IMO.....
