Hi Massimo,
thank you for comment.
I reworked the light halo around the footsteps.
I think digits are OK. From the top - they are aligned or a bit lower than upper part of the strut beween vertical and horizonta stabilizer. And from the bottom, the space between digits and horizontal stabizer is wide as roughly half of the digits hight.
Struts between upper and bottom wings are dark on the vast majority photos I have found. So I made them dark green, not grey like on the R-5.
A have repaced the profile above with the reworked one.
What frames do you mean, plsease?
Regards,
