Hello from MavicPilots

[Cyberpower678]

I'm a total noob and just built my first racer. The next steps are to tune the PIDs. As I never done this before, I would appreciate some insight. I'm using betaflight on an F7 controller.

From what I understand P is stick responsiveness, I is how stead the drone is in flight, and D helps to control the oscillations. Do I have this correct?

Welcome to FPV and the forum. Is there a reason you feel you need to tune? That board/gfu should have a great stock tune. If you have oscillations, it may not be due to tune. This video is one of the simplest tuning videos i've seen

Maybe. I haven't actually tried to bring it up into the air just yet. When I applied minimum throttle, the motors turned on and off so quickly, it rattled the screws out of the motors. Yikes. Maybe my throttle settings are a bit off?

Have you adjusted your end points? If you used ibus receiver signal, its not needed

Also, if you have your flight controller orientation wrong, it'll go nuts. You can set the orientation in betaflight under configuration, if i'm remembering right. Been a while since i've used betaflight. I use raceflight

I did definitely make sure that the orientation is correct, I'll check the reciever endpoints. I use SBUS though.

Sometimes with no props, they'll act funny. With a finger on the arm switch (you can set arm to a switch in betaflight), try it with props on outside, just make sure you can quickly disarm it

Sbus requires endpoint adjustment to work properly

Will do, but I won't be able to report back until tomorrow. When it rattled some screws loose, I lost them. Getting more tomorrow.

I will look into getting them adjusted.

You can use two screws per motor, its all i ever use. Good luck, let us know how it goes. The first build includes a large learning curve but is well worth the trouble

Indeed.

Welcome to DRP Cyber .

What frame, motors and esc did ya use?

What frame, motors and esc did ya use?

Mach 1 Frame and the DJI snail propulsion system. When I armed it in Betaflight, and sent a signal to the ESCs, the motors spun just fine.

 

[VirtueViolater]

Haven't seen much on the snail, it shouldn't be the problem. Set your endpoints, set a switch to arm/disarm, put some props on it and go outside for a test, just make sure you can disarm quickly

 

[VirtueViolater]

How much is a set of props for the snail motors?

 

[Cyberpower678]

I think the entire package is $99

 

[Cyberpower678]

The ESC programmer is an additional $10.

 

[VirtueViolater]

Thats awesome, you are the only member here that I know of with the snail. You may be able to help someone out with it in the future
