Note: Gimbal housing, trim cylinders, and propellers are sold separately.

The item I bought was one to replace something I thought I had accidentally thrown away. A couple days after the boatplicity item arrived I located the like item I already had. I initiated the return process with boatplicity, as I no longer had need of the item. I completed the return request stuff and it said I would be contacted to continue the process but no one has contacted me.

I Called and asked basic question but was told I can not be helped and was referred to sales, which was closed or out of office. I emailed sales and received zero response. Not what I expected.
