You can find cheap modules containing all 3 of those sensors on one single board on eBay. Just attach that to SPI instead of the old sensors. Also, mwii 2.0 is way, way outdated.

She flies.. however, after a few seconds, yaw will start either continue rotating (left) or when yawing right, it will pull hard to the back and crash. Up until then it flies stable.

Yes, and those are not just defective, they're the wrong part for the job.. only rated for 500 mA and probably the wrong pinout.
The residue is some sort of flux.

Replace them with IRLML2502. Cheap to get off ebay and handle up to 4.2A.

Your throttle stick has to be centered at around 1500, and centered when you switch to althold if you want it to stay at that height. Below 1450 or above 1550, it will go down or up.

Tricopter motor directions really don't matter, but having the front two go cw and ccw (or ccw and cw) will take out some of the rotational force because they cancel each other out, so the tail doesn't have to lean as far just to maintain a straight hover.

You have it set up as a serial PPM receiver, but wired up as a parallel pwm receiver.
Undefine both serial_sum_ppm and ppm_on_throttle and it should work, given that you don't have even more receiver options active.
