DEVLOG 2 - Upgraded airfoils , inner design and some touches to the ESC

Hello. This time i better isolated the airflow inside the tube, because it had leaks and low pressure zones which made the flames leaked and could potentially go straight into the EDF and its powerful suction would make completely melt itself. Also removed the previous aluminium foil that was on the tube at the end , like at the exhaust to it would create a more tight space and therefore higher velocity gasses leaving from the nozzle creating more thrust. Then i noticed that the flame tube right behind the EDF was kind off not centered so i cut some nails in half and drilled some holes into the tube from outside to inside and put those nails in a way to center and hold the flame tube in position then just glued them in place from outside. Also tried to use a servo motor to move the slide potentiometer so i could throttle the fan speed as i liked . It can go from 20k rpm up to 110k rpm. at first it starts to work as i want but then just does spins and every time it does throttle it doesnt return anymore to its starting position its like it has lag , and its maybe the codes fault because i dont know programming i fully really on ai for this one. please if someone can help me comment and let me know , i really need help because im planning to use servos and arduino which is connected to a bluetooth module and then i will use to my phone to control it from a safe range and also make it look cooler. And also the last ting i want to say is stay tunned because this thing has a lot of thrust even without the flames so its going to be crazy and im going to make the first test after all of these big upgrades soon maybe in like 3 days because im not home. thank you everybody
