Hoverthings FLIP dihedral 3D printed motor mounts

After watching the Flitetest video of the NAZE32 setup and the use of dihedral on the arms used with the rotorhub I decided I needed to try putting some dihedral into my next build. 

It just happened that I was in the process of looking to build a new arco quadcopter. I have been using my ZMR250s mainly for LOS flying and acro, but wanted something a little larger.

Part of that process was looking for a frame. I was also on a tight budget so the starting point was almost decided for me. I ready had the ESCs and some motors and the FC. So wanting to limit the investment I chose to use what I had.

• Turingy D2830 1000kv with prop adapters (requires cutting shafts)
• RCTimer prop adapters
• AFRO 30amp speed controllers
• NAZE23 FC
• 8x4.5 - 10x4.5 props

So with these parts the options were limited. So I finally dececided on a Hoverthings FLIP sport. It was in budget, and I already have a Hoverthings frame so if nothing else it can be used for spares for my main camera ship.

I designed the mounts to add 5 degrees of dihedral. I use tinkercad for my simple designs. 

The first part was to get the standard motor mount holes in the right orientation to to allow the 5 degrees of angle. The mounts also had to be recessed so that they were out of the way when bolting to the arms.

The Hovethings arms also have 3 holes around the edge of the arm which were perfect to use as mounting holes for the completed motor 3D printed parts. It took a little bit of figuring out angles and getting everything lined up. But once done I printed 5, (For WHEN I crash and break one) 

Here is one full mounted up on the Hoverthings arm.

On a the completed FLIP Sport frame.

I also made some feet for the frame. As I was trying to make it as thin as possiable.

The complete build of the FLIP is here (Including parts used)

Next is flight testing, I have only had a chance to run a couple of batteries through the FLIP since its completetion. Heres a video of its first flight.(Sorry about the lighting)

The next step is to make some mounts that have the right angles to add to other Hoverthings frames that are not standard x configurations (FLIP 360, FPV, FPV Pro)

UPDATE :

Next day, better light second test flight and first crash. The frame is strong and the 3D mounts held up well.

Some raw footage with a 2200mah 25c battery. this time with balanced props and lock nuts instead of the prop adaptor cones which are badly balanced.
