Help! Drone flips when armed.

[S L Holt]

I have speedybee f7 flight controller. Have flown it a couple times. Decided to fly it recently. As soon as I arm it spins up 2 motors full instantly and flips the quad. With or without props on. If I go in to betaflight I am able to control the motors with the slides and they spin according to the amount applied. Not sure what is going on.

Make sure your props are spinning in the correct direction for each corner.

Yes I double checked everything this morning. When I arm two motors spin up all the way. If I move throttle to about half all motors are showing 1500 is. I'm thinking I might have a bad esc. The sliders will however, operate the motors just fine.

Sounds like the ESC system needs to be recalibrated. Motors should not spin on arming. Twitch a wee bit, perhaps but definitely not power up.

That's not always the case. I always set mine to spin slowly on arm so there is a visual clue that it is armed / still armed.

It does sound very plausible that board orientation is incorrect, or motor order is incorrect.

Figured out the problem. It was actually on my transmitter channel assignment. I used speedybee app and on zero throttle the model was spinning g on the app. I went through the the configuration making changes in real time. Watching the model. Then I went through transmitter settings and changed 1-4 channel assignment and the model finally stopped spinning. I disconnected the app. Armed the drone and wallah! It worked. Thanks for all you input. I appreciated it.
