Hello Jörg,
first of all I like very much the way you painted the pilot nacelle, the rain effect is great and i will perhaps try to copy you...
oil level are great too as the "shinethrough" effect. i didn't decide anything yt in mine about this, i have to see more pictures...
Can you tell me more about the roundels? was they hard to install? where have had you to cut them?
last thing , I agree with Xmald about the turnbuckles and will use cotton tube (advantage to be the third one ;-) )
good continuation!
Xan
