Note that the motor mounts on this frame are smaller than the standard 1104 mounts. This frame is designed for the cheap Racerstar BR1103 motors which use M1.6 bolts.

This frame is a pure X frame measuring 89mm motor to motor and you can use a 16x16mm FC stack or a 20x20mm. If you go with a 20x20mm stack, be careful of your ESC choice because I have seen many ESCs that have quite a big PCB that might hit the props.

The frame is made from 2mm carbon and is very minimalist which allows for light weight builds.

I suggest 8000kv or 10,000kv motors on this frame with push on 2" props

such as these ones:

For the FC stack, you can get something called the "Super S" which is a 16x16mm FC with OSD and 6A 4in1 ESC all for about AU$30.

With the 1103 motors only being around AU$5 each at the moment, you can potentially have a very fast little quad for very little money!
