The Spidey frame is quite interesting looking ... I like your Opti 5 though ... I currently have a set of TBS ESCs that I'm not sure if they're going to work as planned... They are brand new 30 amp discovery I got them cheap ... But I will need something more like your Opti 5 or freestyle build frame because I need to put the ESC shout on the arms ... I won't be picky by no means seeing as you're willing to offer A-frame which I'm very grateful for and be willing to do a review on if you're interested
