I think one piece would be nice. I would like to see that scoop incorporated into the cowl somehow. I realize that different motor and muffler combos might interfere, but I like spraypainting a cowl and being done with it. Maybe the scoop could be epoxied to the bottom as a seperate piece once the muffler was positioned. What do I know? The kit is out of the kids hands now. I took it home to finish it up. It took them exactly 5 weeks. That's only a half hour a day and we had 4 snow days. That's pretty impressive. Usually it takes at least 7 weeks. I will take components back for some finishing. I have not made the sccop yet. They will also make the struts. But for now, I getting her sanded for covering. Also bought my wheels today. Excited that they were only $3.99 until I figured out that was for each one. I hate visiting the hobby shop and spending over $60 and not walking out with a plane or an engine, just a bunch of little things. Hope Roger is OKAY. Let us know soon.
