Default RE: Hobby Lobby Skylark e-Conversion

To mount my AXI 4120 motor on the Skylark, I initially tried using the PM41001 Aluminum Motor Mount but found that the frame did not fit in the custom fiberglass cowl. I then tried the [link=http://www.hobby-lobby.com/motormt.htm#AXI1]PM41002 Radial Mount Set[/link], and, although it did fit in the cowl, the length was too short.

The length problem was easily solved by using a common piece of PVC available at any home improvement store or hardware store. The 2" coupler (Schedule 40) was a perfect fit. I used 10-32 hardware with 3" long screws and Tee nuts to secure the assembly. I'm sure that #6 or #8 hardware would also work but I didn't find the 3" length screws at Home Depot.

A small ridge runs along the inside of the coupler center that needs to be filed flat where each screw passes. It is a simple job with either a round file or Dremel tool sander.

The motor mounted easily and is rock solid. I used a little Locktite inside the Tee nut threads to help keep it secure. Note that both down thrust and right thrust are built into the firewall.
