AlfaRC Razer140 3 Inch 140mm Wheelbase 4mm Arm Frame Kit True X for RC Drone FPV Racing

Cheap! It looks so bad! Cheap but only arm-changing style That said, there is no atmosphere that sells only arms (laughs) It's cheap, so you can buy the whole frame and spare parts (^-^) The cut surface of the frame is unprocessed The kit itself is very well done, it's free to assemble, it comes with a non-slip mat for bottom mount and a battery strap (^-^) Upper mountable up to 4S/850mAh I think bottom mount is better than that Standoff is 25mm, with 3 layers, and receivers can be combined with 4 layers (^-^) Over 200g as it should be You can't use 11xx or 12xx motors But there is room for a 3.1" prop if the motor has room for it I think it's a recommended frame (^-^) I took the photo 4S/600mAh, as you can see (^-^)
nice little frame, very well cut and the arms are really thick. p.s. make one in 4in frame pls.
