Novaflier,

The World Models ARF kits are excellent kits, both in build quality and covering. Most of tham also are very good flying planes.

The clear plastic cowls are cheap alternatives of the painted ones to give you the ability to do your initial cutouts on something that allows you to make a couple of mistakes without ruining your nicely painted cowl.

Make the usual templates from paper or cardboard and transfer to the plastic cowl. Cut it till you are happy with the fit, then use that as a template to transfer the patterns to the finished cowl.

Best regards and happy flying
