I'd love to build a high quality Saturn V (I love the sirius kit based on what I see on the web, but have never seen one in person). But I am not HPR Cert'd and my local field only allows up to G's. Seems an incredible waste to build something I won't fly.
I've built the estes kit,... but it got pinched in a move... and would prefer something bigger / higher quality if avail.
(side note: I'm building an LOC 4" V2 currently... I love scale!)
