Thanks, well the thing with many aircraft is there are variations, even on the same type, if you noticed on the shots I posted the landing gear themselves were dark grey while the wells and doors were lighter grey, whereas in this photo the landing gear is much lighter and the doors darker, I think one thing you have with Flankers is variety.
As in here the doors are clearly red on the landing gear and the finish is gloss.
Here the J-15 Flying Shark or as we call it, Flanker, well Sea Flanker to be specific has also got the red doors.
Here also a Flanker with unusual for Flankers, (or any Russian built aircraft,) white wheel hubs.
Here is the guy who designed the badge for the tail art on Red 32, Linden Hill decals made a copy seen here!
This is a decent photo, shows clearly another variation.
This is the SU-35, still a Flanker, but it has white landing gear and red doors, with grey interior!
Basically, paint it whichever way looks best to you, not many aircraft have this many variations!
Then there's the other part to paint lol.
I hope to see some more photos PB! Of your model I mean.
