Alright so after doing a second testing session on water it was a decent success. The remote works really well (no intermittent problem like with the last one) even though the cruise control function isn’t that great since it cuts down to zero immediately afterturning it off to regain control of the throttle which causes you to significantly slow down before being able to re-accelerate. The power bank for the receiver and the water pump worked very well so that’s good. However, I still couldn’t fly. The motor wouldstart studdering/shaking at around 12 km/h before cutting off. I wouldn’t be able to restart right away since the output of the bms would get disabled but after restarting it, the same issue would happen at the same speed. Then I decided to bypass the BMSon discharge and the same thing happened except that I could restart right way without resetting anything. I have a 80100 APS 80KV motor with a 7.5in diameter/8in pitch alu prop and a 14S14P li-ion battery pack, flier 400a boat esc and smart 150a BMS. So basically,the main problem is that the motor starts studdering at around 12 km/h before shutting off if more throttle is given. At first, I thought my propeller had too much pitch but then I mounted it backwards to reduce its efficiency and the same problem occurred.Now I’m thinking it might just be a setting on my ESC. Any suggestions? Can it be something else? It spins really well out of the water and it can fly by itself on the water.
