RE: The Wings Maker Ultimate 40
To mount the electric motor, the stock metric T-nuts were first removed and then #8-32 T-nuts installed into the new positions marked from the AXI radial mount. I used 1" (HLH8855), 1/2" (HLH8854), 1/4" (HLH8853) spacers, and 3" (HLH8875) #3-32 screws from [link=http://www.hobby-lobby.com/brushless-motors.htm#filterValuesRequest,filter_id_88=87|88]Hobby Lobby[/link]. Note that two 1" spacers would likely work here as well but I prefer to have the cowl in tight against the fuselage.
The APC 11x7 e-prop was mounted with the supplied spinner. All hardware was included for the cowl and spinner.
