THANK YOU to our friends and suppliers at Aires/Quickboost for this excellent improvement set for the Tamiya P-51 series! And thanks also to the reviewer corps leaders for making the set available to me to review.
This set takes the kit components and improves them in a major way. If you follow the Tamiya P-51 kit instructions, the kit prop blades are cemented to the spinner back half, then you cement the front half of the spinner to the back, trapping a poly-grommet in the spinner so you can press everything onto the front of the model at the end. It works, but there is a seam at the front of the spinner, and how to paint the whole thing comes into play. I have assembled the spinner and painted it and the props separately in the past; it worked, but the propellers are difficult to set at the proper angle using this method.
