This is mainly a transplant build from a 5" Merica. I really like using the Gemfan Flash 5552 props on all my 6" frames so that is why I wanted to convert the Merica this way too. Unfortunately, it was not a simple switch of the arms. I guess I could have done that, but the bottom plate is a little thicker on the 6". Good thing I also swapped out the motors to a set of brand new Emax Lite Spec 2207 2400kv because I did not have to extend the wires to accommodate the longer arms. I also made a slight modification after seeing the newer version of the Merica-X 5 where they place the cross brace on top of the arm instead of below. Since I cannot do the same thing with the crossbar that I have, the only option is to add a spacer to lift the motor even higher. I 3d printed a 6mm spacer to lift the rear motor a little higher so I can get a larger offset between the front and rear motors.

Take a look at the images below and you will see how much bigger the 6” frame is. The only difference I noticed between the 5” and 6” frame is the thicker (6mm) and longer arms, and the thicker bottom plate. Since the Arms are 1mm thicker I had to modify the arm bumper so it will fit. I did not install the arm bumpers yet, so that is why you do not see them in the pictures.

Update (July 2019) - GoPro 7 Black and Foxeer Falkor Micro Camera

After getting a GoPro 7 Black I could not go back using a Session anymore. With Hypersmooth it makes everything look a lot better. I also switched out the Foxeer Monster camera because I upgraded my Dom v3 to a HDO, so now I need 4:3 cameras and that is why I am now using a Foxeer Falkor micro. I thought I need to switch my Gemfan Flash 5552 props to 6" but so far it flies great with the same props even though the GoPro 7 is twice as heavy as the Session. If you look at all my builds you will see I use the same Gopro 7 case, I just remixed the 3D file and adapted the different mounts that fits my quad. I uploaded the STL file to thingivese if you want a Gopro 7 mount for your Merica too. You can find the link below in the parts list.
