These parts are all to be used in conjunction with the Lama Cargo Hook Frame - They are printed in Polished material - the frame is too big to polish!
The hook has been designed to work with a Savox SH-0255 Micro Size Digital Servo that will fit inside the hook assembly perfectly. 2mm & 3mm bolts are required to complete the assembly including 5mm x 2mm Grub Screws.
I suggest that you buy some 1.5mm Wire trace from a Fishing Tackle to suspend the Cargo Frame - the wire will fit into the Spelter sockets
The hook had been designed to take a load of 2.5 Kilos with dynamic loading of 4.0 kilos
