Hello Mindaugas,
Thank you very much for the nice word´s you spend to my F-15. 
For The realy Triky Question of Plastik or Paper Figures in Scale 1:33 or 1:32 scale
That´s a Problem that I can`t also realy find a solution.
I Prefer to use scale 1:35 scale Tamiya, Hasegawa, Italeri,,Dragon or in Your country maybe easyer to get is ZVEZDA Model Figures.
I think the diference between 1:33 and 1:35 scale is Tolerable,because in real live there are also smaler and Taller People.
In 1:32 scale I know only the Company PREISER but the offer i think like Civilian People and the are expensive.
In 1:25 scale for Tank crew´s I have to say sorry I don´t know nothing about.
In Paper: I have used from KARTONOWKA Magazin # 1/2000 Pilots
from the German Air Force WW II and from KARTONOWKA # 2/2002 some Japanese Pilots and Technick´s also WW II.
In the GPM #157 The E-2 Hawkeye Papermodel are 2 Pilot´s includet.
So that´s all i know.
Sumary i can say the best efford you can reach with 1:35 scale Plastik Figures.
1. You can glue together from diferent People diferent Part´s like leg´s and Hand´s or similar.
2. Yoy can bend them if you try to heat them carefully.
3. You can paint them.
For example I had used a Russian Tank Crew from Company ZVEZDA 1:35
for the Kamov-25 I but some Cardbord under the Co, + Pilot to seat them a little bit higher and it work´s good.
In the Short Sunderland that I have shown, there are also Pilot´s in but you can´t see them beacause the Cokpit is so big it look´s the get loose.
Sorry that I can´t help you enough.
Sincerly an best regard´s
Heinz
