It supports top mount and toilet tank, and has 4mm arms for maximum durability and they are skinny horizontally to reduce drag.
The frame comes with an extra arm, extra hardware and a file to 3d print my awesome canopy, but since the stand off spacing is 27mm, most generic mounts will work. There are 2 places to mount your 20x20 boards, and the motors mounts are ONLY 12X12 MM, No 11xx and similar motors won't fit.
This is a low profile frame for 2.5" props and is a breeze to build. I designed this frame with freestyle and longevity in mind, meaning that is will weigh a few grams more than some other ultralight race frames. It has large prop separation, meaning that there will be less oscillatoins, and there are 2 spots to mount your FC and ESC, allowing afor a one board stack!
Nari 18 Features:
Bottom plate with 2 sets of FC stack holes, which means the FC is not stacked up onto the the esc, allowing you to keep the stack spread out and easy to maintain.
Large canopy to allow for top mounted batteries.
Designed for 11 mm High quality textured standoffs allowing to fit micro cameras
