I thought this rocket would be super hard... in fact it was really simple to build... Estes did a great job with the instructions... if you have built a QCC explorer then you are completely capable of building the BSV... I highly suggest using your CWF on the balsa before you attach them... it will make for sanding a whole lot easier... The build looks awesome when you are done and you will have a feeling of accomplishment when finished... a couple hints for when you are building... ditch the tri-old shock cord anchor and use some kevlar anchored to the transition piece (there is a loop to anchor too) then use some elastic at the end of the kevlar... also add a little bit more nose weight then what Estes gives you... what i really like about this rocket is that Estes had incorporated a baffle like system with this rocket... I'm giving this rocket an excellent rating because it is super fun to build and does offer a challenge to even skilled rocketeers...
