Our methods for cowl cutting are similar. I use card stock reather than clear. I am going to try your method of transferring the template to the cowl. That sounds easier. I've been leaving the template on the plane and sliding the cowl in place to mark the cut outs. Your way sounds like I wouldn't need a third hand!

I'm glad the spinner is a little larger than scale, I absolutely hate grinding out spinners to fit the prop.

Is the bottom of the wing in the typical Decathlon fore and aft stripes?

Thanks for all of your good work.
