ok so AG7 opens the flaps
this is how u land with it
around 340-290 km/h open the flaps and glide a bit toward the runway at around 250 km/h u need to start using Pitch and Roll to land smoothly.
also, I noticed u bleed a lot of speed when u try to maneuver at high speeds this can be fixed with a bit of work.
another thing I noticed is that you have a lot of drag
your original build had around 9k and mine has 10k
again this can be fixed if you want it to be lower

you can use Xray mode to see how I made it work like this
also i did a bit of my own style modifications hope u ok with it
need more help just ask

@XxRxX on my mig-15 if you want

gimme a link to ur build i can make flaps for you if u want
or here a tip:
if you want a landing flap for example,you just make the thing out of fuselage and then put a wing part inside your built body
you can resize wings into like 1% of their original size they still function as normal-size wings
the flap on wing plays a cosmetic role and the actual wing part does the job.
for a flap such as langing flap to give you massive upward lift (helping you to land and take off with low speeds) without turning your nose up or down you need two wings that turn the same way up or down one on front and one on the far behind of your build (i assume its an aircraft).
just ask if you need more help i am here most of the times

here is an example on how i do flaps

if you just want flaps you could just
clamp01(Activate1)
it's what I usually do

@Hiimakeplanes k

clamp(Pitch+(Roll0.6)+(Trim0.25),-1,1)
Here’s the code, put it at input on a rotor

Make custom wings
