I have built a new v2 frame, basically having the propellers inverted was going to cause too many issues and one of the motor plates weren’t totally level, so I scrapped that frame and made a new one. I might do the inverted build for a v3 but i don’t think it will improve efficiency more than 3 or 4% especially with such thin arms.
I also fed the motors through the top plate into the arms, this should be much stronger and looks much neater. The wire coming off it is for flashing the built-in receiver
first test flight didnt go so well, basically there was a lot of vibration and on closer inspection I could see the blade tips weren’t level on 2 motors when they were spinning, so either the motor or propellers were faulty. Moving the propellers around didnt really do much and neither did a second set, so 2 out of the 4 mini 3 po motors were defective. To fix this I have ordered another 4 from an equally questionable seller along with a set of genuine dji propellers from DJI to give them the best chance of working.
