Coming along very well!

See if you can give 1-2 degrees toe in ie both the motor shafts pointing towards each other. Improves stability a lot. I did it for my Twin Challenge

looks awesome!
I have built this plane before!
Please Strengthen the wing more that what FT suggests! MY wing Snapped!
and use diagonal braces on the tail (bamboo skewers) as the tail on this is quite fragile.
I also would recommend to  add wood braces where the Landing Gears go. Otherwise, with every landing, they keep digging in the foam, structurally weakening the fuselage box.
Regards

FT mini trainer is my first beginner plane as of now, though I am trying since 3-4 days in heavy wind condition, here in Orissa wind is pretty strong, monsoon winds, been crashing for a while because panic throw control.

Though I had a lucky few airborne moments a few days back, I observed similar thing, the depron sold here in India is pretty different or lets just say shit quality than the US counterpart, the wing was kind of flapping like a fish in mid air, I can literally see the space between the fuselage and wing lol.

its not like that. you are comparing two different things. their depron is covered with virgin brown paper, which makes them strong.
you can achieve the same, with sticking paper to your depron.

not
thanks prabal trying to backward cg
not backward, you have to move forward. to make it nose heavy.

Your plane has amazing lift , find some open area to fly, or you will bang in trees and trimming will be impossible.

Because you will struggle.
