Default Is trimming needed at all to hover a Quad?

Hi,

when I hover my Quad I notice I have to apply quit a bit of trim on pitch and yaw.

Is that normal? or maybe the gains are too low? or even the Quad wasn't stable when the board was initialized?

I'm just starting so I just wonder what is going on.

Thanks.

All things are dependent on each other.

First, the better your center of gravity, the easier to control.

Motors are critical. With power off, feel your motors, if one feels rougher thean the rest, this will cause issues.
Lube the bearings regulary.

Prop ballance is critical.

If using a round tube for arms, motor position on the tube is critical. Even the slightest twist on one motor can change the dynamics of flight.

Controller position, most require them to be on the cog.

ESC programming. Get then right.

There are so many variables, each has to be worked thru, and each depends on the other.

So you do need a bit of trim to compensate for all these factors, yes?

I actually thought the controller board would sense it is moving and compensate for that on its own...

This is embarrassing... but I figured I wanted to start with something really simple and cheap to see how it goes and learn a bit without being too worried about the thing itself.I have a KK board which I have no idea what version of the firmware I have flashed in, on a HK crappy wood frame...

I am going to flash version 4.7 of the firmware to see if it helps.

Check this youtube video. Laughs apart, you can see the actual thing on the pictures.

There are advantages to wood frames, they do an excellent job of vibration absorbtion. The down side being fragile in a crash.

Take a look inot the DJI Flame Wheel frame, $80. An excellent frame that can absorb a tremendous beating.

Making a frame is simple, Lots of folks do it. Lots of really, really great fliers prefer to do it.

If you have figured out how to flash a KK you are deffinately doing a lot better than a lot of folks!

Enjoy the hell out of what you have!
