The SPC Maker 90NG tends to be unflyable straight from the box, as the F4 flight controller has a gyro that is ultra sensitive to vibrations, and thus will cause the motors to stutter and heat up fast. After crashing another quad with a compatible F3 Flight Controller, I decided to transplant the F3 Flight Controller of the crashed quadcopter to this 90NG.
This is the first FPV flight after this "transplant", I even forgot to change the name in the OSD settings to 90NG, and the receiver in this quad doesn't support RSSI, so it's stuck at 49 all the time.
