Weirder than it looks at first glance.
Since seeing Nurk's Tappers Arcade Bar shot I've been enamoured with the idea of having a cinewhoop, the Squirt V2 is a brilliantly designed frame (and I almost bought one) but in the end I opted to design one to suit my needs (and parts bin!)
Being a pilot of the crash-prone variety, I'm not a big fan of unibody baseplates, and the size of the Squirt's slightly terrified me in terms of the amount of carbon I'd burn through if I snapped a couple. As a result, I went down the separate arm route, taking the arm mounting of the SKEW_R Mk2 and rotating it 45 degrees. There's two different shaped arms to give a hybrid x form (I was gonna go deadcat until I realised that would need 4 different shaped arms and that would defeat the point), and like the SKEW_R it's rotationally but not reflectionally symmetrical. Ducts were designed using formulae from the Capolight blog post.
Component-wise, I went full size on most components, mainly whatever I had lying around. Ordered a set of RCINPower 1506 3000kv motors but I got impatient waiting for them and built it up with HGLRC 1407s instead. Made a prop cutter with a 3D printed part that fits to a Dremel tool and a motor taken off my old Wizard, works a charm.
AUW is A Lot. It's a heavy little bird, lifted fine on the 1407s without them cooking though. The maiden flight quickly revealed some undesirable characteristics, however. The quad felt very loose, with a drift on yaw and randomly yaw hitches too. Flying close to objects also caused some dramatic lurches - not ideal in a build designed for proximity flying. Research at that point revealed those problems to be relatively common, and also difficult to solve. New ESCs, new props, new firmware...none of it solved the issue.
After spending several weekends attempting to solve the issue with limited success, I decided to try a different approach altogether and design a cinewhoop style quad based on what had worked for me so far, rather than what I'd seen from others - this became the Hoverfly.
