Dave's comment: "Ultralight 2mm frame for experts only"

Ultra-lightweight 100mm frame with super narrow arms for minimal wind resistance and thrust blockage. Quick and agile when built light using 1102/1103 motors, 300mAh 2S 45-90C Nano-tech battery, and a lightweight 6A 20x20mm esc. Recommended props in no particular order are RX2535, Racerstar Pro 2435, DYS 2435, 3020's cut down. 2 blade versions of the 4-blade props work well too.

Due to the ultra-light nature of this frame, motors less than around 4gm each are recommended to avoid crash damage.

This "true x" frame is cut so that the grain of the carbon fibre sheeting runs down the length of the arms, rather than the conventional layout which has the grain running at a 45 degree angle. This dramatically increases the strength of these super-thin-arm frames, and requires a different, less efficient layout for AP to cut the frame, and thus is more costly. We consider our frames to be premium and cutting-edge, and that the extra cost of these unconventional frames is justified.

The motor center holes may be too small for some motors and might require countersinking, or drilling to a larger size, just enough to relieve any binding. Please check the circlip is not binding as the motor is rotated by hand. This is done to maximise the frame strength in this area.
