Hi All,

I am beginner to drones. We assembled one drone using STEVAL FCU. 002. board , recommended set. of motors and. propellers along with battery.

We Chose different. frame. than. one recommended . It is smaller in size.

While flying , vertical take. off. could. not be achieved.

Can someone guide please ?

Motor connections , Clock wise. , anti clock wise in reference. to alignment. of. the boards are checked. already.

It is ST board. so. come equipped with all driver , frimware etc.

Thanks in advance.

Early and accurate response is. appreciated.

Welcome @mmdave1, to the community!

You can't see much on your video (start of the motors at 0:2.366 > 0:2.399), but it looks like the propellers are not mounted correctly.

What is their direction of rotation?
Can you please show a photo from above where you can see the tilt of the propeller blades?

Regards

This doesn't make sense: you have to take off before you can be flying!

Do you mean that you didn't achieve enough lift with the motors?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

STEVAL-FCU001V2 is F4, not F0.

What firmware?

The stock firmware basically used to work.

Form the video it looks like a wiring / coordinate system issue.

Hi Peter,

Thanks. for prompt. revert.

We have cross checked with ST documentation and it is in line.

Sharing one photo , Motors. and propellers are aligned. in that way.

Hi Andrew,

That is the issue.

It does. not. take off. properly and does not achieve the lift. though motors and everry other. parts are as recommended. by ST , except frame.

@ KnarfB,

Standard ST firmware STSW-FCU001 . It has come. preloaded with STEVAL FCU00V1.

As beginners, perhaps it would be better to start with the actual frame, motors, and propellers provided in the kit by ST?

STEVAL-DRONE02: https://www.st.com/en/evaluation-tools/steval-drone02.html

That way you know for sure that everything is correct & compatible

BTW: What's. with. all. the. full. stops. in. your. posts?

The direction of rotation is correct, but which propeller with which tilt did you use where?
