I had this same problem yesterday. Went to fly for a commercial real estate job (yes, I have my Part 107) and the gimbal started shaking all crazy. After getting pissed about the prospect of losing the $250 for the job, I went home with my tail between my legs. THEN I remembered how important...

Of course. You're right. I'll throw in the towel on this one.

Yeah, they were even nice enough to label the test points PWM1-4

I did briefly think about simply putting in bigger or more MOSFET's. I don't know now, seems to me maybe, just maybe the nitro/gas engine, variable pitch rotor idea might be pretty epic. AND if it crashes, I'm out way more money LOL. Honestly, I'm just brainstorming here and wondering if...

Hell, thinking about it more and tending to go even more mad scientist, why not get rid of the motors all together and use nitro/gas engines and use the PWM to dictate rotor pitch on a variable pitch rotor wing?

I estimate, by my oscilloscope, approx. 62.5kHz frequency of pulses to the motors, each taking about 16uS

Interested. Let me know how it goes.

my idea was to use the PWM (what you call a servo signal) pulled directly off of the main board (4 per board, obviously) and have them run to completely separate ESC's.. each which has it's own feedback sensing. The power isn't really an issue because I had the thought of having one battery for...

The raw PWM connection from the controller to the ESC circuit

I thought that too... Until I took mine apart and attached an oscilloscope to the test points and found that it adjusts motor speed to maintain level flight in Atti mode, GPS Location in any GPS mode. Of course, DJI could have a value in it's software that says for this much pitch, change pulse...

I'm just brainstorming here. Let's say to design a drone sized where the motors form a square that would be 3 or 4 feet square, for instance. Something bigger. To replace the main board on a Phantom 3 Pro for example is about 130 dollars. This and my own frame with new ESC's, motors, and...

Correct, but if I wanted to put larger motors on it.... to be able to lift more weight

Hi everyone, I have been reading in the "shadows" for sometime now, and decided it was time to speak up. Where my head is at ATM: Has anyone ever entertained the notion of hijacking the electronics on a phantom to drive larger ESC's and thus create a larger QC? In theory, you could use all...
