Can a model of like 25 grs resist a dog of no less than 50 kgs?
Yes, it can, even if i didn´t modified at all (too small to can add counterweight excepting 6 nails each one)
This just made stronger my stereotype about Soviet and Russian things XD
Are simple, and very tough ;3

I am thinking seriously in get a 3rth one and transform it to ski units. Because, Russia= -273 C in my mind XD

Depite all, i managed to take a very few decent images of my Li-2 , aka DC-3/C-47 built in the Soviet Union
