I found some time and space to test the bird.
It hovers nicely, but only with Horizon mode in iNav as i found i have COG problem depending the batteries used.
With a 115mm long 3S 2600mah there was serious forward leaning in ACRO mode and i couldn't get it off the ground at all.
Enabling the Horizon mode though it hovered like a charm.
I also tested with 2 x 1000mah 3S Nanotechs connected in parallel that were placed in the back of the battery space.
The COG problem was very light, almost gone.
Again with Horizon mode was perfect.

I couldn't keep it in the air more than 5 minutes cause all the batteries are very old and do not keep much juice.
Actually i had them stored in my refrigerator for around 5 years !!!
They survived but they cannot hold anymore in such demanding usage.

I wait for a couple new 3S 3000mah batteries.
With the changes i have done to the body they will fit if the declared sizes are correct but i have to solve the COG problem somehow.

For now the total weight with the 2600mah battery is 850 grams

Hey Alexa, could you possibly upload your modified components? I am planning on building one fairly similar spec wise as your build. I would really appreciate that.

BTW, a month ago i had a crash.
One of the front feet was broken.
But the actual problem was with the base at the point of the screw that holds the rear feet.
The strength of the hit was there and as the weak point is there the base broke.
I designed a support under the rear feet to split such hit to bigger area and i hope will hold better.
And also extra feet that will be screwed at the front of bottom
