First of love your channel because of it me and my son started your swappable series and are now building foam planes together so thank you for your awesome father son project. That being said i love the multi rotors and just drooled all over my keyboard when the review for the stingray came out but that price tag is a bit much. i have seen some diy VPP quads and even hobbyking eluded to working on one using the kk2 board. i was wondering if the mad engineers at Flite test could build one and maybe do a scratch build on it. What do you say guys VPP Quad Scratch Build Challange?
