XK A800 – brushless motor update

As a fist step of rebuild my XK A800 from toy to serious GPS glider is replace brushed motor to brushless.
I decide to go to small and light 1306 tinywhoop motor, and as there no way of use folding glider props, 3D printed parts will must be used to fits original props as well as adapter for motor mount.

Motor:
EMAX RS1306 2700KV:

This motor (diameter 16.8mm) together with my 3d printed adapter perfectly fits into fuselage. It is half of the original motor weight but 3x stronger. Also lifetime for a brushless motor should be much longer.

you can buy this motor here: (with few cents for me)

Just to compare original motor and brushlees EMAX:

Weight: 23g original motor with prop ws 16g EMAX
Thrust with 2S lipo: around 50g original motor and around 150g for EMAX

ESC:

FVT LittleBee 20A

…

This ESC is probably overkill with max current (20A) but is light (5g) and cheap, bidirectional Dshot can be used, so perfect for that. As A bonus can be hidden in motor holder and cooled by prop air.
