Absolutely great work @yak-54 I really love it. Did you get to test it yet? If so, does the vibration of the IC engine affect Pixhawk? I have no experience in IC, but read a lot that the vibration is a big problem and people get errors due to it. I am planning to build a plane with IC as well. Thanks

vibration should not be an issue with the cube as the motor is rubber mounted from the frame
