4mm Prop Saver

Against my better judgement I have listed 4mm prop savers. I’m not a fan of prop savers especially on powerful set-ups and I shiver at the thought of one of these on a 300W motor that it is likely to be attached to. They are however a very neat lightweight adaptor with two sizes of collar machined on each surface with securing long grub screws that also double as the band attachment. The fitment suits GWS propellers. APC propellers will require slight modification to the hub or adaptor ring to suit. Supplied without 'O' ring. Please ensure that whatever is eventually used to retain the prop is securely attached and double checked before running your motor.
