Hello,
That's all right, everybody is a little stupid, I'm too. Learning helps, but just a little bit
OK, jokes over. If You can find a sitting pilot figure,made out of styrene, then it can be converted with a little surgery. The sequence is as follows: cut the figure at the joints (hips, knees, ankles), file a little, join again, optionally reinforcing the joints with thin wire. Then you correct the pose (look in the mirror for reference) and fill the gaps. After everything dries take a fine file and redo the surface with all the clothes. That's it, easier said than done! But it's worth a try. You learn and nobody's gonna have a figure like Yoursafter You're done. So, I wish You success and a nice day
Pawel
