You say you want to save that fragile GWS prop, or that "expensive" ACP slowfly?  Well, here's the solution.  These adapters allow freedom of movement for your prop on all axis in the event of a crash, and can really reduce prop damage.  There are two hole sizes available:
3.0mm - For MP Jet Gearboxes, GWS EPS, Ultrafly Gearboxes, Hacker B20 Geared 4:1, and other 3mm-shaft motors and gearboxes
3.2mm - For AXI 22 Series and Mega 16 Series motors, and other 3.2mm-shaft motors and gearboxes

The adapters include the M2.6x8mm screws as pictured.  You can use rubber bands as you like to secure the prop, but be sure to replace them frequently.  We've tested the adapters up to 160W input power, but do strongly suggest a maximum of 100W for safety.

GWS props up to 12" fit the adapters "as is".  For APC props, glue the 4.8mm adapter ring into the prop, then open the hole to 5mm. NOTE: The rubber bands pictured are too thin for actual use (they were only used here so you can see the adapter).  Use thicker bands for actual assembly!

Disclaimer:  Air Craft will not be responsible for any prop-related injury.  It is your responsibility to maintain and operate your model safely.  NEVER place any part of the body to the side or in front of a spinning propeller!!

Air Craft EPS Aluminum Upgrade Shafts

	These shafts are made to work with the 3D Wobbly adapters above.  Note that when assembled with the Wobbly Adapter, the end has a perfect radius for the smoothest prop-saving action.  More than that, these upgrade shafts, which are made from the hardest aluminum available, are much stronger that the stock GW-EPS-6AC steel shafts.  They survive the average hard landing without flinching, where the stock shaft would be bent, yet again....  Finally, they weigh less than half compared to the stock unit!
