The color scheme is what sold me too[8D]. I am ordering the engine this week. Depending on how eager I get I may rush delivery and fly this weekend. We'll see. As for the smoke system GO FOR IT! I don't think the plane is too small. One of my fellow clumb members told me tower had a deal on the magnum .90 4c. i'll check that out but I am still leaning toward gms .76
Keep me posted on your progress.
Oh yeah you may want to look at finding a taller landing gear. I think stock is waay too short.
