A few things I don't like right off the bat. First, it looks like one heck of a complicated build. I took a quick skim through the manual and they're talking 5 and 30 minute epoxy, goop glue and such... not sure if I want to go through all that. Second, carbon landing gear! Might be better off using the spring stuff
And yeah buying 4S packs might be an issue for me.... I'll consider it though.
