PatternFlyer,
If you want more pictures with details, just tell me, is no problem...

I think that the YS110 is more than enough power, if you do not want to modify the fuselage this engine is the best choice.
I tell you that the OS91FX is too a good choice, the vertical is unlimited... think about that... [8D]
The paint I used is polyurethane bicapa, 2 components, for finishing (automotive paint).
I did prepare the colors bases with the samples of Oracover (I used Oracover films).
