I'm trying to mount my Novak SS5800 on newly acquired 2nd hand 12L3.5 (well, with lots 12L4 parts on it..). SS5800 ESC is big on my 415 but on my L3.5 it's way too huge, especially when I still have a cooling fan on top of ESC. Guess I better wait till either Novak's new ESC or LRP's Sphere released, than starting my brushless pan project..

btw, RCWORLD.ch has a very clean photo of Jon Orr's Sphere+Neo 12L4
