F450 losing height.

Hello everyone!
I recently built a F450 with the following specifications:
1. A2212 - 1000KV BLDC Brushless Motor.
2. Mystery Cloud 30A BLDC ESC - Brushless Motor Speed Controller.
3. Naze32 REV6 flight controller with dRonin.
4. 3300mah 3s LiPo battery
I used dRonin because its easy to configure and use (and I am new to cleanflight). I have used a similar setup before and it worked perfectly. But this time whenever I increase throttle, it goes to a few feet normally, but it doesn't stay there, it comes down and after that, no matter what I do (even full throttle) it stays on the ground(the propellers keep spinning just above neutral).
I noted that in the motors tab, after running setup, the PWM frequency of the front ESCs is 400 while that of the back ESCs is 50. If I change both to an equal value, the ESCs don't spin properly at all.

I thought of flashing the ESCs with BlHeli but I am not sure if mine are compatible or how exactly do I flash them(I tried BLHeli Suite but they just won't connect).

Also, the setup runs fine with YMFC - AL by Joop Brokking but I busted my second gyro (MPU6050) and I think they are not very durable.

Please help me. Thanks in advance.

Did you use those same ESCs? Those seem to be about as basic/old school as you can get, the kind you would use in a plane. You would have to do some soldering and get an AVR tool to even try updating the firmware.

Maybe try a manual ESC calibration?



Assuming you are on a budget, and want to keep costs low, even these would be a more quad friendly with a 2012 version of SimonK.

Hello, thanks for the reply. I did not use the same ESCs on my previous setup. But I had another quad(a ZMR250) which also has simonk ESCs (12a) and I ran into the same problem, and I had used the same setup before which worked perfectly. The only difference is time. Which begs the question, could it be the battery?

PS: The budget is not a problem so much as the shipping time to India.
